Thermal mass and insulators are the best materials that help absorb the heat and gradually release it to make the building cooler. These materials help to slow down the heat transfer and control the temperature.


Leaving home is as challenging as staying home without any heat insulation on these intense heat days. Air conditioners can resolve this problem and beat the heat, but the expensive electricity bill makes it difficult to use this effective equipment. Despite being a helpful gadget, AC is bad for the environment. So, everyone must use cool building materialsåÊwhile building their sweet home.åÊ

Some people forget about this material at the building time, and some have barely any idea about it. Thus, if you are planning to build your dream home or make your home naturally cool and cut the extra expenses on air conditioners, you must read this article till the end to learn about the material that effectively absorbs the heat and makes your home cool.åÊ

How To Build A House That Stays Cool In India?åÊ

A building constructor uses various materials that help absorb the heat from the wall’s surface. Below are some of India’s beståÊenergy-efficient building materials in India; youåÊmay opt for your house to reduce the heat.

Use Eco-Friendly Building Materials

Eco-friendly material helps to cool the building without affecting the environment. Materials like bricks, stone, and concrete are good heat insulators because of their higher thermal mass, which helps absorb the heat and release the heat gradually to make buildings cooler. But some people use low thermal massåÊmaterial, which does not help absorb the heat.åÊ

Thus, you need to use these materials in bulk to make your home cooler on the heat days. The thermal mass property of these materials helps to make night warmer and day cooler. Besides these materials, timber also acts as a good insulator of heat.åÊ

Window Placement And MaterialåÊ

We all know well-positioning windows are the best way to welcome the air and keep heat out, which helps cool buildings. But in summer, the air from the windows is also very hot. Hence, you should choose the right glass for your windows, which helps reduce heat transmission and make the building cooler.åÊåÊ

Thermal InsulatoråÊ

When designing buildings in modern times, constructors mainly use high insulation material. But traditional buildings are only made of thermal mass. However, materials like phenolic foam, polystyrene, cellulose, polyurethane foam and styrofoam are good heat insulators.åÊ

These materials have higher R-values, which are thermally resistant. They slow the heat transfer to keep buildings cool and reduce heat loss. So it would be best to use these materials while constructing your home to keep it cool all day long.åÊ

Glazes And PaintsåÊ

During summer, the sun remains at its peak, and the intense heat rays directly fall on the roofs. However, if your budget is insufficient to install ceiling insulation in your building, glazes and paints are the best choices to reflect solar radiation and reduce heat.åÊ

High-performing roof paints help absorb the surface temperature by 10‰ãÄ of the roofs. Compared to ordinary paint, solar glazing on windows is also very effective in letting the sunlight inside the room but obstructs the sun’s heat.åÊ

ALC Wall PanelsåÊ

The composite material of ALC wall panels is the best way to retain and maintain the home’s temperature. The excellent thermal insulation helps keep indoors cool even on intense heat days.

AAC BlockåÊ

While discussing the best materials that help reduce heat in the home, AAC blocks are one of the best options. Its exceptional thermal insulating quality helps absorb heat and offers solid insulation without thermal bridging. Thus, you can make your home cooler and reduce electricity expenses.

Fiberglass Insulation

Like other thermal insulation materials, fibreglass is also very helpful in minimizing heat transfer. Fibreglass is a tiny shard of glass made of glass powder and finely woven silicon, the best heat-absorbing material for the room. You can install fibreglass in your building because it is the best insulation to keep heat out.åÊ

How To Reduce Heat From Concrete Wall?åÊ

We all use concrete while constructing any building as it is its foundation. Despite being a high thermal mass, concrete does not work as it is covered withåÊlow thermal mass materials.åÊHence, the following ways help the concrete to do its best job.åÊ


The sun generally remains on the top in summer, so the heat directly falls on the roof. The concrete absorbs the sun’s heat, which makes your home hot. Thus, an external horizontal shading like louvres and overhangs are the best material to block the heat waves. These materials help eliminate sun exposure and protect the roof of your house.åÊ

Ceiling InsulationåÊ

Ceiling insulation materials like tiles, panels, forms, and grid suspension are the best way to enhance thermal comfort and reduce the heat of the entire floor. Buildings with ceiling insulations offer incredible thermal performance and significantly save energy. Concrete walls can work effectively when your roof is thoroughly insulated, absorbing the heat and slowly releasing it.åÊ


Besides protecting the exterior covering of the roof, waterproofing of concrete roof is one of the effective ways to keep the top and terrace cool. The practical formulation of the material used in waterproofing helps reduce surface temperature and cool the building.

How To Keep A Building Cool Without Air Conditioning?åÊ

Suppose you are tired of the costly bills of your air conditioner and want your home to be naturally cool. These ideas act as a homemade insulator and will help you resolve your issues.åÊ

  • Cool your roofs by installing ceiling insulators.åÊ
  • Grow more plants and trees to shade your home.åÊ
  • Use thermal isolation materials in your home.åÊ
  • Open your windows and use cooling curtains.åÊ
  • Use light colours or cool colours in your home.
  • Use evaporating cooling gadgets.åÊ

How To Reduce Heat In Buildings?åÊ

If you have already built your house but unfortunately missed these materials during construction, don’t worry. Here are some practical ways to resolve your muddles and reduce the heat of your building.åÊ

  • Use material that stays cool in the heatåÊor low-solar transmittance glazings.åÊ
  • If your window faces south, you can shade your window with awnings and overhangs. For west or east-facing windows, you can use ells, porches, and wind walls for shading.åÊ
  • Do not use inappropriate ventilation fans.åÊ
  • Install radiant barriers in attics to provide air space.
  • Use a light colour for walls and roofs.åÊ
  • Allow roof ventilation or attic.åÊ
  • Use energy-efficient electric appliances.åÊ


Now that you know the best ways to beat the heat wave and stay cool this summer, apply the tips to keep your home cool. Instead of using low thermal mass materialsåÊfor your building, use high thermal mass and insulator materials to cool your building naturally. These materials not only help to reduce the heat but also help to make your home warmer on cold days.åÊ
