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. Petra Buildcare wall skin coat gives the best result even with single layering on the wall. It protects the wall from extreme weather conditions, chemical reactions, noise, and fire-related problems. It is a ready-mixed, lightweight, and eco-friendly product with high density and tame shrinkage behavior. It can be applied to cement blocks, bricks, and concrete units. The wall care power has no greenhouse gas emissions and is the most natural energy-saving substance for your wall. The skin care coat provides esthetical higher-level finishes to the wall along with removing any peeling or blistering in the wall. The Wall mortar is a simple and powerful solution for less energy consumption with cost reduction. The ready-to-mix solution can save your energy bills up to 35% when applied with necessary masonry units during construction.
