Thermal insulation in Karachi

In Pakistan, the warm climates have a reputation to become fierce and it only increases as each year pass by due to global warming. Not what types of remedies are available to take refuge from such heat intensity. If you are thinking about air conditioning, you have hit right on the spot Air conditioning does work well, but the energy consumption during summer are soaring into the highest which is almost become unbearable to experience. Not to mention the energy crisis which has been a part of Pakistan for quite some time.

Fiberglass insulation

Let’s start off with the most advanced form of material which has not one but several applications in our modern times. Being lightweight and cheap material, it can also come into play as a thermal insulation material in Pakistan which is used to keep your home cooler during warmer climates. If you are wondering, what’s so good about fiberglass material that it has secured the position to present itself as a highly versatile material of the 21st century. For that, we might need to go further to learn about its construction first. Fiberglass is a fiber-like material made from sand and recycled glass. Due to its composition, its highly resistant to fire, and doesn’t absorb moisture. Any option which has these two properties has a higher value of heat Resistivity.

Cellulose Insulation

Made from recycled newspaper, Cellulose is cheap and most popular thermal insulation material which is used in homes. But with all the advantages, there are indeed some negative points for cellulose. Since its made from recycled newspaper, it’s highly combustible, so additionally, we need to apply fire resistant chemicals to make it more reluctant to catching fire. Not only that, but it can also absorb water to a large quantity, which in return lowers the Heat Resistivity for the material. So why does cellulose insulation ever being used in our home? The simple reason is the large acceptance due to its availability in the form of recycled paper. To improve the heat insulation towards your home, we used cellulose to make it thicker to get number of R-value in its composition.

Polyisocyanurate Insulation

Polyisocyanurate insulation material is made up of plastic which as a closed cell formed. This composition helps to airtight the gases which finds it difficult to passes by the material, which secure around R-5.6 to R-8. The best thing about Polyisocyanurate insulation is it can come in the various form for its application, for example, it can be used as form spray, liquid or solid form, as per your requirement. This insulation material greatly reduces the environmental heat coming in from outdoors.

Expanded Polystyrene insulation

For solid walls or concrete buildings, similarly, in Pakistan, there is expanded polystyrene insulation which plays an integral role in preventing heat towards your home. The composition of expanded polystyrene insulation is carried out through plastic beads is fused together that looks like a transparent colored object. As per the concrete wall that has been used in Pakistan, the hollow concrete blocks are used where expanded polystyrene insulation which greatly resists heat radiation for around R-3.8 to R-5.

Spray Polyurethane form

Polyurethane has been considered to be an ultimate insulation material for homes in Pakistan as no matter what material your walls or roof is made up of, whether its concrete, steel sheets or wood, the polyurethane foam can be applied over the walls quite easily, with generally a greater amount of insulation resulted out of it. The only disadvantage is its cost, which is above the average.

Radiant Barriers

For hot summer heat that comes in Pakistan, every summer season cannot along get decreased only through insulation material, but we need to add into another form of insulation which reduces heat but also reflects the heat away from your home. One of which is called radiant barriers. These special type of blocks are available in the form of solid sheets that can be situated outside of the roof. Radiant barriers are a special type of resistant material whose main purpose is to reflect the direct sun rays back into the environment, similarly like heat proofing paint.

Does thermal insulation in Karachi protect from leakage?

The main role of thermal insulation in Karachi is to ensure that high temperature and the summer heat is unable to enter inside of our homes. But because the application of thermal insulation in Karachi is an investment many people would like to double-check on the fact that does thermal insulation in Karachi protects from leakage in the first place?

Let’s delve more into this concept and to make most people at ease that there’s surely some insulation material which helps in protecting from leakage and seepage along with securing the roof from high temperature.

Polyurethane foam spray

Also known as PU foam spray, is considered one of the highly popular solutions that one can avail of for thorough protection from heat-related issues.

With the help of polyurethane foam spray, we can have solid security from leakage and seepage over the roof as well.

The PU foam spray helps reach the small places from where the water might come inside from the roof. It’s vital to have a solid leakage proofing solution that every point is closed off from where the leakage could enter your home.

Bitumen membrane with Foil

Talking about different types of thermal insulation in Karachi that works to keep leakage and seepage at bay as well, no one can beat the material of bitumen membrane with foil.

The foil effectively secures your roof from high temperature, which the membrane sheet which is properly airtight over the external roof surface, stops all the leakage and seepage effectively.

The bitumen membrane has also one of the highest years of life for which it can protect from water-based damages over your home.

Thermopole with bitumen waterproofing

There’s always the workaround solution to apply thermal insulation in Karachi as well as make it waterproofed from all dangers of leakage and seepage.

Thermopole is a highly popular insulation material that aims to secure heat temperature even during heatwaves. Although when applied bitumen chemical over the surface, we can have a double ability homebrewed together. That includes protection from leakage and seepage from water-based damages.

Talking about other materials used for thermal insulation in Karachi, simply applying waterproofing chemicals over them will work, especially when all damaged concrete or surface is repaired.


Insulation material which is used in Pakistan helps homes to decrease the total heat radiation inside your home. Through various methods based on your preference, you can greatly benefit from reduced energy consumption as well as make your environment a better place with a low amount of carbon dioxide over the territory.
