Petra BuildCare – Wholesale Thermal Insulative Building Material Manufacturer

The path towards sustainability starts at home and incorporating sustainability with the building materials is an efficient way to be sure that our homes are not subjected to wastage of energy. Insulation is one of the most productive ways to control energy consumption at home. Energy-saving is a must in today’s environment because of the fluctuation in climatic change. Residential buildings are proving to be dominating the insulation market because with the changing climate, it has become imperative to adopt insulation methods. PETRA BUILDCARE provides several energy-saving solutions for commercial as well as residential constructions. Insulation works by maintaining and controlling the temperature inside the homes in every season throughout the year. But the question which arises is that how the insulation works? Heat flows from a warmer area to a cooler area which means that in the season of winters the heat will flow from the heating appliances to outside leaving the house cold and vice versa. The appliances also have to conduct more heat because of this and electricity bills increase as a result. But with the help of proper insulation in a house, these problems can be tackled very easily. The method of insulation is also advantageous because it helps in making the home a comfortable space and also has noise reduction and energy-saving capabilities. There are many ways to insulate a house, the first steps include insulating walls, roofs, doors, windows and floors. Insulating walls are most important because in any conventional house they are responsible for 30-40 percent heat losses. PETRA BUILDCARE has introduced several insulative building materials.

We possess special thermal insulation solutions- ThermoShield and ThermoPlast. These solutions are the future of new homes and insulation are made possible with the help of thermal insulation wall putty and thermoplast wall mortar.

Wall Putty – Past, Present and Future

Homes are not built in a day a great amount of hard work and feelings are attached to the whole process of building a home. A person puts a lot of effort into making their dream home a reality but in the midst of the whole process one usually forgets to pay attention to little details. The use of proper construction materials is very important and use of good quality wall putty plays a very big role in the construction process. The demand of construction and wall plastering materials like mortar, wall care putty, and distemper has increased largely and is predicted to emerge as a major market in future. There is also increase in competition with the increase of the wall putty market and many brands have emerged lately but the most brands have forgotten that there is a need for their products to be eco-friendly as well. Most of them are stuck with the past and lack advance building materials. There is a need to make your dream home an eco-friendly one because of the fluctuation in climatic change and the ecosystem of earth. PETRA BUILDCARE with its energy saving solutions and advance building materials have helped in evolving the wall putty market and is simultaneously contributing towards a better future as well.

The Past and Present

In the past, plaster of paris (POP) was used more than wall care putty but as people are focusing towards sustainability it was replaced. Even though, POP has its own benefits as it is mostly used for making ornamental elements and designs but wall putty is a much more cost-friendly, sustainable, and durable material. The rise in urbanisation, especially in Asian Pacific Region and South America resulted in need of a more durable and powerful material. There are mainly two types of wall putty- acrylic putty and powder-based putty. There is also use of primer and a mixer to prepare the putty. But as the evolution of Putty many new materials have emerged like matt finish wall powder, wall polish powder which have helped to make the quality of wall putty excellent. There are also products with waterproof wall care putty, primers based on white-cement and all are focused on contributing towards providing a shiny surface with no dampness. But most of the newly launched products have failed in the present because of the high fluctuation in the climatic change and global warming. The mere waterproofing technique cannot help when heavy rainfalls results into dampness and tearing of the wall surfaces. There is a demand for a more durable and efficient method in today’s uncertain times.

Interesting Facts about Advanced Building Material

For the socio-economic development of any country, the Construction industry plays a very important and crucial role. As the world is becoming technologically advanced every day, there was a need for advancement in building material for the new generation.

Advance Building Materials is the use of high-technology appliances for construction. The aim to introduce Advanced building materials is that there was a need to make building and infrastructure smarter, sustainable & energy-efficient, and more resilient. In simpler terms, ABMs are like digital engineering that is not only favorable for the environment but also increases profitability through economically viable solutions. Innovation and transformation are always important to change the cliched ways through which things are done. The use of nanoengineered materials, biomaterials, fiber optics, and super hard coating materials provides an innovative alternative to traditionally used construction material.

How do ABMs become so popular worldwide?

The traditionally used construction materials such as cement, bricks, concrete, wood, glass, and steel have provided versatility and low-cost maintenance for years. However, due to rapid growth and urbanization, there was a need to replace traditional construction materials with advanced technological units.

For example, the traditional cement is replaced with Portland Cement as it consumes a large number of scarce mineral resources and is environmentally friendly. The United States and China are the highest emitters of carbon dioxide with annual emissions of around 3.2 billion and 2.8 billion carbon emitters. It is estimated that by 2050, the demand for Portland cement will reach 6000 million tons a year as it is providing excellent results in both cold and hot regions. By 2030, it is assumed that 30% of the building units will be energy efficient.

The wave of innovation and environment-friendly construction was seen in 2015. A survey conducted by McGraw-Hill Construction reveals that 51% of the construction industry are using advanced building materials to transform their conventional way of building into ultra-modern construction. 61% of the companies in Europe and the US have succeeded in shifting their construction business towards the green building by 2019 from 13% and 28% in 2015 respectively.

One of the advanced building materials used in modern construction is Energy Saving Solutions. PETRA BUILDCARE has invented the first of its kind ThermoSolutions (ThermoShield and ThermoPlast) that are manufactured using Hollow NanoSphere Technology. This advanced technology prevents the transfer of heat which eventually helps in saving money on utility bills. These Thermosolutions protect the wall from damage and reduce the cost of maintenance. The Department of Energy recommends the use of Cool Roofs to save energy. Cool Roofs have the ability for solar reflectance, thermal emittance, and lower utility bills which provides comfort in the building. The solar reflectance index of PETRA BUILDCARE Thermo-Shield is measured 110/91 which makes it the best coating for cool roofs. ThermoShields have a greater R-value than ordinary wall putty and they can be easily applied on a flat, sloped roof or corrugated metal roof.

Another popular advanced building material is concrete admixtures. These admixtures are adding value to the walls by providing sustainable infrastructure, durability, and long-lasting protection to the walls. Their high workability, compressive strength, ability to resist high temperature, and energy conservation propensity has made concrete admixtures one of the most demanded construction unit in India, China, Brazil, Africa, and the Middle East. One of the market surveys claimed that the global market of Concrete admixtures will reach $16.32 billion by 2022.

Advanced mortar and micro silica are also among the most used advanced building material for construction. Advanced mortar is used to hold bricks or stones together. It is a mixture of cement, sand, and water which furthermore provides tensile bonding strength to the surface. It also provides great compressive strength, durability, and uniformity to the surface. Micro silica on the other hand is composed of fine solid glassy spheres of silicon dioxide. The particles of micro silica are finer than fly ash and are less than 1 micron (0.00004 inches) in diameter. Thus, advanced building materials are gaining momentum in the construction industry everywhere. They are taking the level of construction to next level along with providing comfort to the buildings.

Energy Saving Solutions – Worldwide Rising Demand

The present population of world is estimated around 8 billion and the consumption of energy is measured 17.4 Terawatts every day. From lights to laptops to cars, everywhere there is consumption of energy in a large amount. For example, an average use of laptop consumes ~40W of energy whereas a typical LED bulb consumes 3 watts energy everyday in daily household. A typical car engine exhaust ~150,000 W energy which typically accounts to 20-30% energy consumption of a person in a day. Government agencies such as Energy Information Agency (USA), International Energy Agency (OECD), Exxon, OPEC and BP conduct surveys to know the real consumption of energy in the world. They bifurcate the source of energy production from renewable and non renewable resources in the following categories: Nuclear energy (5%), oil, coal and natural gas (80%). Fossil fules such as coal, oil and natural gas produces energy ~ 110, ~ 50, ~ 50 respectively in the present day.

With urbanization and rise in population, the heating and cooling appliances are responsible for consuming a lot of energy every day. A market survey revealed that the energy consumed by the world today is 37% more energy, then it uses in 1980s. Due to innovation and technology, this percentage is increasing everyday. A lot of energy is consumed in Construction of building. The building sector accounts for 40% of the total energy consumption in the US. Major appliances such as electricity, lightning, HVACs, and miscellaneous usages consumes 11%, 18%, 35% and 36% electricity respectively. Construction and building sectors are always accused for high consumption of energy and emission of greenhouse gases. The emission of CO2 in the UK from construction sector accounts for 47% of the total CO2 emission in the entire country.

One of the recent researches claimed that with the use of advance technology and high-tech equipment, the consumption of energy can reduce to a significant extent by 2030. The commercial energy consumption would be reduced upto 21%, and the residential sector energy consumption would be lessened up to 30% by 2030. One of the efficient ways to save energy during the process of construction is to provide proper insulation to the building. Thermal coatings are highly efficient, flexible and provide thermal resistance to the building. The wall coatings are filled with vacuumed sodium borosilicate and have water-based pure acrylic resin system with less than 100 microns in size. The thermal coatings are non-toxic, environment friendly, and acts as a sealed cell that covers the entire structure

They also have the power to reduce the noise transmission with an effective range from -40 Deg C (-40 Deg F) to 375 Deg C (700 Deg F). The wall skin coats are chemically resistant, helps to maintain the temperature of the house, reduces the flow of energy and is filled with ceramic microspheres. The thermal insulation coats are four times fire resistant and provides a variety of architectural colors to the house.

PETRA BUILDCARE is one of the best companies which is dedicated to supply the energy saving solutions to the customers. Their energy saving solutions (ThermoShield and ThermoPlasts) are designed in such a manner that it provides a complete protection to the walls. The energy saving solutions are built with Hollow NanoSphere Technology which is still not discovered in the market till date by any company. The energy saving solutions are eco-friendly and reduce the flow of energy upto 35%. This in turn reduce the consumption of electricity by cooling and heating appliances. The energy saving solutions are replacing the traditional methods of construction.

Wall Insulation Coat – One Should Know Before Apply

As the world is moving fast towards modernization, the construction of skyscrapers accounts for a significant fraction of the total energy consumed in the country. The developed countries are always held responsible for the high emission of greenhouse gases as their energy consumption in commercial and residential buildings is comparatively high. For example, the construction sector in Europe and the United States accounts for 26.8% and 22% of the total energy consumption of the respective country. One of the recent research on the construction sector reveals that the use of heating and cooling appliances increased in the developed countries with an average rate of 7.5% between 1996 and 2008. With the growth of the industrial sector at a fast pace, the average energy consumption by the industrial sector is evaluated to be 63.1% in the millennium year. In the year 2008, the total energy consumption by the HVAC (heating, ventilation, and air conditioning) in the residential sectors of Mexico was measured as 9.3 TWh, which corresponds to 19.6% of the total energy consumption by the entire sector. This energy consumption was later increased by 24% which concluded that HVACs are the third-highest energy consumer’s in any country

Some of the effective measures for reducing energy emitted by HVACs (heating and cooling appliances) is through proper insulation methods which would result in the reduction of energy consumption. However, the working of insulation apparatuses (wall putty, wall mortar, wall skin coat, and wall polish powder) depends upon the R-value. R-value is the ability of insulation material to reduce the flow of energy. The greater the R-value, the more effective it is to reduce the heat flow. The concept of applying the thermal coating is becoming popular in India, China, the United States, and other European countries in recent years.

Things to keep in mind before applying Thermal Coatings

One of the primary things to keep in mind before applying wall insulation to the interior and exterior surface of the wall is the absorption of solar radiation and infrared emission to the atmosphere. During the daytime, the consumption of heat on the rooftop and exterior surface of the building is high as compared to the night. Thus, the wall skin coat must balance the heat transfer quotient in such a manner that there will be no load on heating or cooling appliances.

An ideal wall care powder exhibits thermal resistance through R-value that ranges from 0.53 to 3.52 m2.K/W. It can reduce the energy transfer up to 170 kJ/day for models with a roof albedo of 0.2. If you want to calculate the actual cost of your thermal insulation then you need to evaluate the cost of purchasing plus coating applied on the wall and then subtract it with the energy savings accrued during the lifespan of insulation.

The development of technology in the world has also affected the way the construction industry works. Today, conventional building methods are replaced with technologically advanced methods. For example, to maintain the temperature of the house, there are a variety of Thermosolutions available in the market.

Before choosing any insulating material you must comprehend the R-value of the product. Loose fibers such as fiberglass, mineral wool, and cellulose provide maximum R-value. For every 8-23 inches thick fiberglass its R-Value varies from 30-50. Other materials such as Fiberglass batt, polyurethane spray foam, extruded polystyrene foam board, and Polyisocyanurate foam board provides R-value 30, 12.6, 4.4, and 6.5 respectively.

Keep in mind to provide proper space in your attic. If there are empty corners and shallow areas where the insulation coat has not been applied or if the area is over coated, it will either result in overheating or suffocation without proper ventilation.

One of the best companies which provides the best thermal coating for walls is PETRA BUILDCARE. The wall skin coat provided by PETRA BUILDCARE can reduce the flow of energy up to 35%. The wall skin coat is easy to apply and provides resistance to water, quick bonding, high coverage, and good strength. The skin care powder has a high R-value and it prohibits the flow of energy from one direction to another if applied with proper dimensions. Thus, it is an effective solution for a residential or commercial building in warm or colder regions.

What is Composite Thermal Insulation Mortar?

One of the primary concerns in the world today is the enormous consumption of energy in the commercial and household sector. As the natural resources are depleting and fossil fuels are scarce, the need to develop energy-efficient products are in high demand. It has been observed that in household sectors most of the energy is consumed by the heating and cooling appliances to regulate the temperature of the house. Thus, there is a need to develop energy-efficient masonry units so that they provide a layer of protection around the building frame. Buildings promote the development of the national economy and provide a large number of employment opportunities to the people. In the United States and European Union, the construction sector contributes 65% and 42% respectively in the country’s economy. The concept of thermal insulation in masonry units was started in Germany during the 1950s and 1960s. It became popular after a decade to deal with the energy crisis and to provide comfort in the building. Today, the European ETICS is leading the world with approximately € 3.3 billion (material price) and around 163 million square meters are used for manufacturing masonry units. For innovation and new construction, various types of insulating material are used like extruded polystyrene XPS, expanded polystyrene EPS, mineral wool, and cork boards, etc.

It is estimated that by 2030 Skscrappers will roughly consume one-third of the global energy and water every year. Presently, the masonry units used for constructing edifice constitutes almost 40 billion tons of black carbon emission every year. By 2050, the construction of commercial and residential buildings will be three times larger than what it is today thus the need to use eco-friendly products is necessary to save the future.

In recent years, the physical and chemical properties of mortar have been the subject of intensive research. Primarily, the thermal conductivity and microstructures of mortar have been discussed to determine the aggregate composition needed for the construction. Various research was conducted on moisture content in the wall concluded that the thermal conductivity in the wall increases up to 70% when the cement mixture came in contact with the moisture. The mortar has a thermal conductivity which decreases the impact of moisture content by 38%, providing excellent thermal resistance to the wall. Mortar when added with expanded perlite exhibit 60% to 80% reduction of thermal conductivity whereas when added with fine aggregates it resulted in 75%-100% thermal conductivity in the wall.

In the saturated state, the thermal conductivity coefficient of the mortar is 70% higher than in the dry state. Hence before the construction of any new building, it is important to evaluate the proportion of fine aggregate, humidity, water, temperature, and admixtures ratio to mortar in order to yield better thermal performance. The impulse technique is also used to measure the thermal conductivity of the ThermoPlast wall mortar ranging from dry to fully saturate with water. An ideal mortar is believed to have thermal conductivity between 0.055 and 0.14 W/mK and bulk density between 600 and 1,100 kg/m³.

Benefits of Thermal Insulation Mortar

  • Thermal Insulation Mortar has high strength, strong bonding force, and good construction performance. Thus it enables trouble-free construction operation.
  • ThemoPlast wall mortar is non-toxic, fire-resistant, eco-friendly, and has low shrinkage capacity.
  • The wall skin coat provides strong adhesion, good workability, and water retention potentiality.
  • The wall care powder protects the wall from cracking and peeling issues.

Method for Mortar Preparation

  • The consistency of water is the most important step to keep in mind before mixing PETRA BUILD CARE ready-to-mix ThermoPlast wall mortar. Add 0.7-0.9kg of water to 1kg PETRA BUILDCARE wall care powder to make a smooth paste. It should be a particle-free uniform paste with semi-solid consistency.
  • When applying a layer on the flat surface, apply 6-8kg / m2 on a 15mm thick wall. No need to apply a thick coating on the surface as the wall care powder is efficient enough to produce the result in a single coat.
  • Leave the mortar for 24 hours to dry completely before applying any other coating of primer/paint.

Things to keep in mind

You must calculate the vertical and horizontal wall measurements to apply wall mortar in an appropriate manner. If the necessary proportion is not applied to the wall, it will cause a hindrance in regulating the temperature

If you are re-applying the coating on a brick wall then either you must choose hot-dip galvanized steel wire mesh or alkali-resistant mesh cloth for proper coating.

Do not add unnecessary admixtures to enhance the properties of ThermoPlast wall Mortar. The packet contains the necessary additives for providing the best result.

Study of Thermal Properties in ThermoPlast Wall Mortar

Architectural spaces played an important part in building structures. There is a demand for creative, innovative, and original architectural designs for commercial and residential buildings. It is observed that thermal insulation in buildings is the most practical and cost-effective way to improve the energy efficiency of the building. Ameliorating significant saving solutions can improve the reduction of energy consumption in the building. The role of thermal conductivity (K Value), thermal diffusivity (α value), and specific heat capacity (C-value) play a crucial role in determining the energy required for regulating the temperature of the building. The flow of energy in the building occurs through free electrons and molecular vibrations. The builders initially evaluate the location where the building is to be constructed to determine the thermal diffusivity. To terminate the flow of energy from the interior to the exterior surface or vice-versa, it is important to appropriately calculate the C-value and K-value of the masonry units.

The ThermoPlast – wall mortar used for construction is made up of fine aggregate, cement, and water. It can be categorized into plastering mortar and masonry mortar. The difference between masonry mortar and plaster mortar is that the initial product is used for binding blocks, bricks, and stones and the latter is applied to fabricate smooth and imperishable surfaces. Intending to evolve the flow of energy in the buildings, the construction industry is developing masonry units with thermal insulation capacities. To provide the best thermal resistance to the wall there is a need to calculate the energy required before manufacturing the building. All the components need to be evaluated like the mortar, concrete blocks, shelf angles, and vertical/horizontal joints.

In modern masonry construction, Portland mortars, lime mortars, and hydraulic lime mortars are very frequently used in construction. Depending upon the structural requirement and environmental conditions, the flexibility, durability, and compressive strength of the mortar are evaluated. One survey conducted on the compressive strength of mortar indicated that the ideal ThermoPlast – wall care powder should have 1.5–2.7 W/(M. K) thermal conductivity, 0.87–1.04 kJ/kg.K specific heat and 0.89–1.26 (x10-6 m2/s) thermal diffusivity. A paragon wall mortar must be porous as they have high thermal conductivity and diffusivity. The pore size of ThermoPlast – wall mortar should vary from 18 μm to 946 μm depending upon its cement-to-sand ratio. The thermal performance of the building depends upon the thermal properties of the material used while construction.

In concrete masonry construction, mortar occupies approximately 7% of the total wall area. Its contribution in providing thermal resistance to the wall depends upon the R-value. The mortar reduction effect on a wall’s R-value is directly proportional to the thermal resistance value of a concrete block. The conventional block building provides 8% heat reduction. If you decrease the area of mortar joints the amount of heat loss would be reduced by 11% in the building. Acrylic fibers and Polypropylene are added to the mortar to provide the best thermal insulation to the walls. The reason for adding Polypropylene and Acrylic fibers is polypropylene has a K value between 1.44 and 2.25 W/(M.K) whereas acrylic fibers have a K-value ranging between 0.77 to 1.4 W/(M. K) which enhance the properties of the mortar. Much research conducted on the properties of mortar also suggests that the mortar produces different results when mixed with different substances such as fly ash, coal bottom ash, and sand.

Petra Buildcare ThermoPlast – wall mortar contains excellent heat-insulating properties. It is lightweight, reduces energy cost, and is considered best for creating masonry structures.

Role of Wall Care Powder in External Thermal Insulation Composite Systems

For decades the role of wall care powder in energy efficiency has been underestimated. Earlier it was believed that strong structural buildings are those that are made up of blocks and bricks with no cavity. The durability of the wall is measured with solid dwellings of cement or wall polish. Solid walls buildings are the most common construction that can be seen everywhere. A lot of new researches have been conducted on masonry units that changed the perspective of people. Now the importance of wall care powder in conserving energy is considered as an aspect while constructing a new building.

The measurement of the thermal conductivity of the skin coat is measured with U-value. The ideal U-value for wall polish power should be around 1.3–1.4 Wm−2 K−1 to provide thermal resistance to the wall. However, this measurement differs on the type of masonry units that you are choosing for construction. Supposedly you are choosing solid bricks for constructing the wall then to provide the ideal U-value the thickness of brick must be 220 mm and it should be coated with the dense plaster of 12 mm. Today, the modern bricks are manually designed 220 mm long for bearing the load of masonry walls.

Source: Google Images (What is ETICS?)

One of the primary reasons that normal brick walls are not able to regulate the temperature of the walls is ‘Air Cavities’. It means the air penetrates the house through the sides or spaces between the bricks. As bricks are made up of different patterns to construct the walls, spaces between ‘headers’ (straight aligned bricks) and ‘stretches’ (side laid bricks) allow the air to permeate inside the house. To cease this air perforation you should apply a 5-10 mm wall joint of ThermoShield. You should keep in mind that the length of the ‘header’ by width should be more than the width of the ‘stretcher’. This will build a solid wall segment.

Some of the common occurrences in buildings are cracks, dampness, and shrinkage of the walls. The reason for this is constant exposure to the sun, water penetration, and weather intrusion. The masonry units used for construction are bricks, mortars, or sandstones which are porous thus they have water absorption capacity.

Even if there are chances of 1% water intrusion in the wall, it can cause decay in the entire building. Thus, the wall care coat is an essential thing to protect walls from external damage. The improper plaster could lead to holes in pipes and a weak drainage system. Hence, it is essentially important to use a wall care coat that is waterproof, durable, and protects from harmful UV radiations.

The modern ETICS used for the exterior walls are easy to apply, economic in cost, and protect the wall for a longer time. The thermal insulation wall polish power is equipped with expanded polystyrene (EPS) which provides continued thermal insulation to the edifice. Thus, the consumption of the energy decrease with constant thermal condensation to the wall. The exterior wall of the building requires high insulation protection as compared to the interior one due to its constant encounter with the changing environmental circumstances. However, there is no need to apply a thick layer of wall skin coat. A good quality skincare coat provides the best results with a thin layer coat applied on the wall. PETRA BUILDCARE ThermoShield and ThermoPlast is an Acrylic co-polymer silicon-based water repellent wall coating. The thermal resistant coat is a unique combination of conventional cement with Hollow NanoSphere Technology. The wall skin coat is FDA-approved, eco-friendly, and provides long-lasting protection to the wall.

Guidance for the application of ETICS components on the wall

  • The wall polish powder that you have chosen for coating on the wall must have a workable consistency.
  • The skin coat must have high compression strength and improves the mechanical property between cement and its substrate.
  • The wall care coat must be crack-resistant, impact-resistant, and tolerate seasonal changes with effective strength.
  • The wall skin coat should be applied with the suitable primer to provide a matt finishing touch to the wall.
  • Before choosing any wall care coat you must check whether the product is following International safety standards or not. The chemicals used in the wall skin coat should not harm the environment.

Thermal Insulation Mortar Mixture for Fire Protection

In the modern world, there is a great demand for improvements in the energy efficiency of the buildings as they are accountable for significant energy consumption and emission of CO2 in the atmosphere. As the construction industry plays an important role in the development of society there is a global call for amelioration in the thermal operation of the masonry units. Today, there is a huge demand for the construction of new buildings or refurbishing the existing ones. External Thermal Insulation Composite Systems (ETICSs) consist of all the masonry units used in construction. One of the important aspects to keep in mind while constructing commercial and household buildings is its fire-resistant properties. A lot many surveys were conducted on ETICSs to understand the possibility of fire safety, fire spread, and elements that have fire-resistant power.

When any building catches fire its concrete mixture gets completely dismantle and the steal embedded in the building further acts as a catalyst in the transfer of heat. Hence, the temperature of the building rises to the extreme which results in the complete collapse of the building. The tensile strength of steel gets reduced around 20%-30% once it is exposed to a temperature above 250 degrees Celsius.Looking at the situation, earlier there was a huge demand to install firewalls for active fire protection. The firewalls can automatically detect fire when the warmth rises above the prescribed temperature. However, not only such appliances prove costly but they also do not prove durable due to their truncated lifespan.

With years of experience and dedicated research in the field of construction, PETRA BUILDCARE came up with a pre-configured fire-resistant cement-based mortar. The pre-bagged mixture is imbibed with Hollow NanoSphere Technology and can be used for building concrete structures and buildings. The ThermoPlast – wall mortar is thermal resistant and provides protection from extreme heat. The mixture consists of ceramic beads which is hydraulically bound and expands when exposed to high temperature. If the building is exposed to extreme temperature (above 700 degrees Celsius) the beads will expand up to twenty times its original size thus forms a protective shield around the wall. The ThermoPlast- wall mortar is specifically designed to provide strength to the wall under unexpected loads. We have taken into consideration additional safety for the structural building. It is important to keep in mind to secure the adhesive strength of the wall mortar so that it remains indifferent from the seasonal changes. If the ThermoPlast – wall mortar is not water-resistant then it might get affected by the outside air. If you are using cementitious surface insulating mortar then it should have a water absorption coefficient to be 0.2 kg/m2 h 0.5 or less. The external insulation should be 1.1 N/mm2 so that it retains the thermal conductivity and prevent moisture permeation into the wall. To suppress the heat penetration into the wall, there should be a coating of 3mm ThermoPlast – wall mortar so that the building remains ineffective from the extreme heat.

Advantage of Fire Protection ThermoPlast - wall Mortar

  • The pre-packed wall mortar mixture is easy to apply
  • No need to form a thick layer around the wall. A thin layer of wall mortar is effective enough to provide heat resistance to the wall.
  • Eco-friendly, approved by FDA thus it does not harm the environment
  • It is a pre-bagged mortar mixture hence there is no need to add extra additives for fire protection.
  • It is already tested according to the international general rules and standards.
  • Cost Performance: No compromise in quality or quantity
  • The wall mortar mixture is durable and long-lasting which reduces the idea of future maintenance.

What to keep in mind while using ThermoPlast - Wall mortar

  • You should not add additional toxic gases to the mixture which could muddle the configuration.
  • The process of application is already prescribed with the mixture. Do not apply more than the advised coating on the wall.
  • Apply the ThermoPlast – wall mortar on an even surface. A patchy, rough, or uneven surface will not provide the desired results.

How to Increase Thermal Resistance (R-Value) of Your Wall?

R-value is basically the thermal resistance of the wall which prevents the flow of heat from one direction to another. If the R-value of any building is high thus it has the ability to slow down or resist the energy flow from the interior to the exterior surface or vice-versa. It also depends upon in which area you are living. For instance, colder regions require a greater R-value than the warmer regions to maintain the temperature of the house.

What should be the ideal R value for the house?

Nowadays the masonry units are equipped with thermal resistance power. Its main aim is to regulate the temperature of the house along with providing a strong structural building. Typically the exterior surface of the house has an R-value ranging from R-30 to R-49 including attic spaces and ceilings of the house. To reduce the energy of the house or regulate the temperature the R-value should be in between R-12 to R- 22.

Many people prefer blocks over bricks wall due to their cost-effectiveness. There is no denying in the fact that concrete blocks are more cost-effective than brick walls but they can never be ingrained with thermal resistance power. Thus, you can save money while constructing a building but will pay an extra charge on utility bills throughout your life. An ideal block wall typically has thermal resistance power ranging from 1.9 to 2.5. The reason for this is concrete block walls have cracked joints which allows the flow of air from the exterior to the interior surface. The rim joint at the top of the basement wall in block walls is another part through which air penetrated inside the house. Thus, Block walls can never be considered best for providing thermal resistance ability to the house For increasing the R-value in the house you need to add extra appliances like rigid foam, seal, furring strips, and mortar to airtight the boundaries of the wall.

Factors determining R value

  • Quality of insulating material that you are using for your house.
  • The region where you are living as colder regions has a lower temperature than the milder ones. Hence, the arctic provinces require a greater R-value than the warmer suburbs.
  • The lifespan of the insulating material that you are using as a means to enhance the R-value of the house.
  • The amount of moisture content in the house or in the insulating material that you are making use of.
  • The way of installation. Even if you are using high-quality premium grade insulating material and it has not been installed properly it will not increase the R-value of your house.

Tips to increase R-value of the wall

  • Reduce the air Infiltration in your house
  • The insulating material that you are using must provide a thick shield around your house thus you need to calculate the amount of material required to insulate the house.
  • Use that insulating material which does not become compress when applied to the walls. The compressed material will not render maximum R-value to the house.
  • You can use products such as vacuum Insulated panels, aerogel, phenolic foams, and polyurethane to provide insulation to the house.
  • You can also use ThermoShield – wall putty to provide thermal resistance to the walls.

How to increase R-value with ThermoShield – wall putty?

A wall made up of bricks and cement can provide energy resistance by applying ThermoShield – wall putty. The wall coat manufacture by PETRA BUILDCARE has thermal insulating properties that help in resisting the heat flow from one direction to another. This ability to prevent the energy flow helps in maintaining the structural dimension of the house. It further helps in decreasing the electricity consumption by 30% – 35% depending upon the type of insulating wall polish powder you are using.

PETRA BUILDCARE ThermoShield – wall skin coat is FDA approve, eco-friendly, easy to apply, and provides complete protection to the house. None of the companies till now have manufactured ThermoShield – wall polish powder using Hollow NanoSphere Technology. The skin care coat can be used on brickwork, conventional building, precast, and gypsum boards. The wall polish powder not only proves cost-effective but also provides shielding from hairline cracks, chemical reactions, and weather changes.
