Roof heating is one of the most common concerns among Pakistanis. During the summer season, when the temperature is high, it becomes unbearable for people to live in their houses. Their houses become heated because of the trapped heat by the roof. If you are also worried about the rising heat during the scorching summers, then you are on the right page. In this blog, we will discuss the anti-heating solution ‘Roof Heat Proofing.’ Stick with us.
What is a Roof Heat Proofing System?
The roof heat proofing system is a type of system where more than half of the roof is not directly in contact with the heat. In a country like Pakistan, where we experience four seasons, our homes must be made according to the temperature. During summer, Punjab and Sindh regions are extremely hot with over 40 degrees. However, we have a monsoon season, which is between July and September. We experience heavy rainfall, and the chances of flooding are also higher. Due to these different seasons, our homes must be durable, and the construction should prepare them for our weather conditions.
Heat Treatment on Roof
As we discussed, the weather conditions in Pakistan and many other countries are extremely hot. To mitigate the heat effect, people use air conditioning, which consumes a lot of energy. Air conditioners also produce harmful gases, and not everyone can afford to have one. There are many methods used in Pakistan for heat treatment on roofs, which help the citizens a lot. Moreover, you will easily find many heatproofing contractors whenever you decide to hire one.
Let’s learn about the most common ways used for roof heat proofing in Pakistan.
Elastomeric Paint
Elastomeric paint is a high-build coating that is made to protect masonry surfaces. These coatings protect your stucco from rain and can also create a waterproof system. It is a high-build, water-resistant, and durable coating for exterior surfaces like roofs and walls.
The best feature of elastomeric pain is its ability to expand and contract as heat is applied to it. This process helps to prevent the roof’s trapping heat and also reflects around 60–70% of sunlight into the atmosphere.
White paint has amazing solar reflectivity, which reduces the energy consumption of your homes. It also keeps your house pleasant and cool. The application of this paint is done by using special heat-proofing equipment like sprayers, rollers, and buckets.
Important: Note that specialist personnel are required to apply this paint to your roof. The professional person will know how much paint is required to mix with water, and how many layers of paint should be applied in the most feasible way.
Foam Insulation
This is another effective way to protect your home from immense heat. By installing layers of foam on your flat rooftops, you can see the difference. Foam is a solid insulation material that can be directly installed over the roof, or you can also install it between layers during the construction.
Interestingly, foam insulation is one of the most used methods for roof heat proofing treatment in Pakistan. The materials used for this foam insulation are aluminium oxide foam, wood foam, cementitious foam, fibreglass insulation, and polyethene plastic foam.
Thermocol Sheet
Many people knew thermocol as the Coca-Cola of roof heatproofing. Thermocol is completely synthetic, and it is also called polystyrene. Polystyrene is also extracted from petroleum products and is easily accessible.
Thermocol is usually situated as a false ceiling, and the heat entering into the roof is unable to be trapped effectively. However, it has a low melting point, so it can get burnt over excessive duration in the summer season. This sheet is still among the top heat treatments on roofs in Pakistan.
Polyurethane Foam
It can be the last resort in terms of roof heat proofing in Pakistan. It is an expanded foam that is applied through spray equipment with a highly secure suit to protect oneself. The properties of polyurethane are used as an insulation material. It is used as a flat roof, sloped roof, steel roof, or corrugated sheet roof.
It can also be applied either to the exterior or interior of homes and on the walls. It can be easily applied either in semi-liquid, solid, or liquid form.
Reflective Foil Sheet
The best things in the world are the most simple, accessible, and basic ones. The same can be said for heat treatment on roofs in Pakistan. Simply applying white paint, form, or insulation may seem more scientific or advanced, but what if reflective foil is used instead? It is known without a doubt that heat is reflected on a silver body, or if it is mirror-like. The use of reflective foil sheets is a great option that helps to prevent heat from entering your house and gets a cooling sensation without turning on the AC, thus saving energy.
Lastly,
During the summer season, the heat is always unbearable, and even air conditioners consume so much energy. In Pakistan, electricity bills during summers skyrocket and put a significant financial burden on them. Keeping this condition in mind, people tend to find ways they cool down their house roofs to minimise the heat effect. Here comes the famous roof heatproofing system. It can help you a lot to cool down your house a bit, which will make it less hot than usual. The air conditioners also work well when the house is not burning with direct sunlight heating the house.
