How to Keep Cement Sheet Roof Cool?

My sister stays in Delhi. Last summer when I visited her house, I realised that she was trying to take steps to keep the cement sheet roof of her home cool. I asked her how to cool cement sheet house, as learning this is crucial to preserve energy efficiency and indoor comfort.

What is the Process of Cement Sheet Roof Cooling?

My sister mentioned some effective strategies which are as follows;

• Reflective Roof Coatings: 

Apply a reflective roof coating that has been specially formulated to lessen heat absorption. Coatings that are white or light in colour work well to reflect sunlight and cut down on heat input.

• Insulation:

Install enough insulation on the roof to stop heat from the outside from entering the building. Foam or reflective foil insulation are other viable options.

• Roof Ventilation: 

Installing ridge vents and soffit vents will ensure adequate roof ventilation. By encouraging ventilation, warmer air can go out and cooler air can come in.

• Shade Structures:

To prevent direct sunlight from reaching the roof's surface, construct shade structures like pergolas, awnings, or shade sails.

• Cool Roof Tiles or Sheets: 

If you're thinking about replacing your roof, choose cool roof tiles or sheets that are made to reflect more light and retain less heat.

• Green Roof: 

Install a green roof, also known as a living roof, to capture solar radiation and use it as a natural cooling and insulation system.

• Ceiling Insulation: 

The internal ceiling should be insulated to stop heat from escaping into the living area.

• Regular Maintenance: 

To guarantee that the roof functions at its best, keep it clean.

By combining several strategies, you can minimise the need for excessive cooling methods like air conditioning and maintain a cooler cement sheet roof, improving the comfort of your living area.

As the temperature continues to rise in different parts of our country, people are finding different ways to escape it. To beat the heat this summer, I installed aluminum insulation on my terrace using Thermocol sheets, aluminum foil, and gunny bags. The aluminum foil helps reflect light, which makes it suitable for insulation. Let me tell you how I made this cooling roof sheet:

First, you need to buy aluminum foil, gunny bags, and thermocol sheets (of the thickness of 1-inch each). The amount will depend on the space that you are looking to cover.

On the roof, spread the gunny bags evenly just above the room that you are looking to keep cool.

After that, place Thermocol sheets above the gunny bags and cover it all with aluminum foil sheets. You need to make sure there is not any air gap between the Thermocol and aluminium foil.

Don’t forget to keep some bricks on the sides to ensure stability.

I hope now you know how to make cooling sheet for house.

This way, the heat absorbed by the aluminum foil will get further reduced by gunny bags and Thermocol sheets. You will be able to achieve a temperature drop of about 5° Celsius with this process. By lowering the temperature, you will be able to lower the amount of power used by an AC in the room.

You may find the use of this concept in different places, such as on the roof of a train compartment that is painted silver to reduce heat absorption. You may also find it in many auto-rickshaws, buses, and cars too.

This is all about the house cooling sheet.
