As a country near the equator, it is not a big shock that Pakistan is one of the hottest countries in the world. Its high temperature has taken so many lives due to dehydration and heat stroke and is continuing to do so. Even with air conditioners on, it is hard to be always kept safe from this scorching heat because of the lack of electricity in our country. So to be able to have a liveable temperature in homes other places is not just a luxury but a necessity.
Here’s where roof heat proofing comes into the scene! There is no doubt that roof heat proofing has been doing so well since ever. So let us get to know more about roof heat proofing and why is it so effective!
What is Roof Heat Proofing?
Humanity has always been using different methods to prevent excessive heat. In a hot climate, the greatest source of heat is solar radiation. Roof heat proofing can prove to be a great help in keeping the excessive amount of heat away.
Roof heat proofing is a popular and very effective method to make your building more bearable to live in. Roof heat proofing uses various materials and designs to prevent the heat from entering and leaving the building. To maintain and ensure thermal comfort for the people in the building, roof heat proofing uses appropriate techniques. The main reason for heat transfer is due to conduction, convection, and radiation.
In simple words, roof heat proofing uses a thermal barrier of some specific material and applies it to your building. That material helps in reducing the heat by not allowing it to enter the building. With a good roof heatproofing system, we may not even need an air conditioner. This can help us in saving so much money.
How Does it Work?
Now you may have a general idea of what is roof heat proofing but how does it even work? Now we know that our buildings can get exceptionally high due to solar radiation. This heat can enter through our windows, roofs, and doors. But for the topmost floors of the building, the roof can be the biggest source of rising temperature.
Roof heat proofing can also include coating the roof with a certain chemical. It can be cheap and easy to apply. That chemical reflects heat and traps it outside the building causing the temperature to lower significantly. Hence, being the reason for the heat insulation. It can also be applied to concrete, wooden, and metal structures.
We can also apply it to the inside of the walls to be more cautious
Ways of using roof heat proofing
After evolving so much in heat insulation, we can say that there are a lot of ways in which we can trap the heat outside the building. Let us know more about the popular and effective insulation methods. So, you can know what type is more suitable for your environment and needs.
The best Roof Heat Proofing techniques you can try are
- Roof Cooling Chemical or Paint
- Built-up Roofing (BUR)
- Metal Sheets
Roof Cooling Chemical or Paint
Roof cooling chemicals or paint can be one of the simplest and most economical techniques. Seemingly white paint is applied to the area. This white paint is a chemical that reflects the sun’s rays. This can happen due to two properties. Firstly the white color does not absorb much visible light and secondly, the chemical is specially used for keeping the surface cool.
This paint is easy to use because it can be applied by any kind of brush and on any type of surface.
Built-up Roofing (BUR)
The built-up roofing technique, also known as BUR, is being used for hundreds of years now. The only things that are changed are the materials being used its manufacturing. It is still the most commonly used roofing method used for low-slope roofs.
The reason for its preference for a low-slope or flat surface is its continual plane. It uses alternating layers of asphalt and reinforcing fabric. Then lastly topping it off with stone or gravel.
Metal Sheets
Metal sheets are more preferred for slanted roofs as they can reflect sun rays. But these metal sheets can absorb heat which can also be a huge problem.
To get over this problem, we use roof cooling chemicals on them. This can add up to the properties of metal and bring out more reflectivity.
Final Thoughts
Roof heat proofing services can benefit you more than you think. They are not only used for cooling purposes, but they can also provide you with better conditions for the building. It stops the building from reaching a certain level and forming a mold-type surface. It is also responsible for maintaining the temperature and making it more liveable. They are a better option than air conditioners because they are not much effective when the roof is way too hot. People living directly under the roof can benefit so much from roof heat proofing as the roof exerts 90% of the heat during its peak.
The roof heat proofing technique is worth a try as they are very beneficial for people living in Pakistan.
