Concrete roofs are embedded in Pakistani culture. They play a significant role in hosting family gatherings, enjoying rain showers and playing cricket in every season. Despite being an important aspect of the house, a concrete roof can be a trap for heat and solar energy. Hence, it can transfer solar energy to your home’s interior. In such a case, it is essential to heatproof your concrete roof.
The process if heatproofing in Pakistan ( https://www.heatproofing.pk/heat-proofing-services/ ) is extremely thorough. Handling the project, all by yourself, is near impossible. As a result, you must hire a professional service to assist you with the task. Although, if you are curious about the art of heat proofing a concrete roof, you can go through the ensuing guide.
Avoiding Thermal Bridging
Thermal bridging is the first thing that is considered. Thermal bridging refers to the situation, where your house has direct contact with the sunlight, hence, it holds the capacity to conduct heat into the interior of the home. To avoid thermal bridging, you can lay down a layer of polystyrene analytic strips between the metal frame and its facing, such as a styrene board. This should be done on the external and internal surfaces of the frame.
Adding Vapor Barriers
Vapor barriers can act as a protective shield against condensation. In a concrete roof, adding vapor barriers is essential to avoid any setbacks in the future. Pakistan’s extremely hot weather conditions make it necessary for you to add a vapor barrier on the surface of the insulation. This ensures that the insulation remains intact, even after undergoing harsh and humid weather conditions. Vapor barriers can be created with polythene material, reflective foil, foil-backed wallboard, as well as with waterproof painted surfaces.
Fill All the Cracks and Holes
In order for the insulation to be effective, you are required to fill any cracks or holes within the roof. If your concrete roof has any cracks that create a cavity between your roof and your home, it is imperative to fix it right away. In the case that the cracks are not fixed, your insulation would become ineffective, due to the increasing rate of condensation. You can do this by adding roof tiles, or by layering a foil-backed building blanket (anti-condensation blanket) underneath the concrete roof.
Heat proofing is only effective if every inch of the house is covered. Hence, you must fill all the gaps in your insulation, so that the heat does not pass through!
