Want a Cooler Home? Apply These Techniques When Building Walls

The temperature inside the house is not only affected by the weather outside, but also depends greatly on how the wall construction is designed. Many people try to make their homes cooler with the help of air conditioners or fans, even though thermal comfort can actually be achieved by building the right walls.

Here are some wall construction techniques that can help create a cooler home naturally:

1. Use Materials with High Thermal Insulation Power
Materials such as red brick, lightweight brick (AAC), or natural stone have better heat-absorbing properties than ordinary lightweight bricks or concrete. Good thermal insulation properties help keep heat from outside from entering the house directly.

Tips: Lightweight bricks tend to be lighter and quicker to install, while red bricks are known to be durable and provide a natural cool effect.

2. Make the Walls Thicker
Thicker walls take longer to conduct heat from outside to inside the room. This means that the temperature inside the house can be more stable and does not heat up quickly even though the outside temperature is high.

Example: A wall with a thickness of 20 cm will be much better at absorbing heat than a wall with a thickness of 10 cm.

3. Add a Layer of Insulation
Thermal insulation such as glasswool, aluminum foil, or styrofoam can be installed between layers of walls or inside the house. Its function is to retain heat before it reaches the main room.

Additional benefits: In addition to retaining heat, insulation can also dampen sound from outside.

4. Avoid Heat-Absorbing Finishes
Dark paint or wall surfaces with rough textures tend to absorb more heat. Conversely, light colors such as white, cream, or light gray can reflect heat and keep the indoor temperature cool.

Suggestion: Choose exterior paint with heat reflective technology for maximum results.

5. Add a Canopy or Climbing Plants
Walls that are directly exposed to the sun all day long will heat up faster. You can reduce this exposure by installing a canopy, secondary skin, or planting climbing plants on the outside of the wall.

Advantages: Plants not only make the house more shady, but also add to the aesthetics of the house facade.

6. Design Ventilation and Windows Wisely
Walls that support cross-air circulation and adequate openings will help remove hot air from inside the house. Fresh air can enter and replace trapped air.

Design tips: Place windows or vents facing each other so that air can flow smoothly.

Building a cool home does not always have to depend on electronic devices. By paying attention to how to build walls—starting from the choice of materials, thickness, to adding insulation—your home can feel cooler naturally. Not only is it energy efficient, but it also creates a healthier and more comfortable living environment.
