Different types of internal wall insulation methods in Pakistan

Internal wall insulation methods

Insulation for homes has been going into the discussion for more than 100 years, the times when people started to feel warm weather unbearable. Turning on the air conditioning has to become a burden and its well understood that there should be various methods that don’t require a heavy bill to pay each month. With a variety of Internal wall insulation methods used practically in Pakistan, the result is outstanding. Instantly you will feel the difference with and without the internal wall insulation is being set up. In today’s edition of our article, we want to give you an overview about various types of internal wall insulation methods used in Pakistan and to learn the expansion of this heat proofing market that has been into the spotlight for recent years.

Benefits internal wall insulation

You may be wondering, what is the difference between internal and external wall insulation, as both are the same thing? It’s true, that both mean the same thing, and they work on the conjunction of restricting the extra heat into the home. But there is a basic advantage of using internal wall insulation, which is the easiness for application for internal wall insulation. It has great benefits for solid walls as well, which is usually the case for houses in Pakistan. The important aspect to prevent the air from entering into the home. In other words, air tightness panels are a compulsory part of the internal wall insulation methods. So how to achieve that, and what components are used for this purpose, we are going to learn that below:

Vacuum Insulated panels

This is the most expansive internal wall insulation methods being used in the market. The Vacuum Insulated panels incorporate vacuum inside the hollow section of the material, which is very expensive during manufacturing. Also, the performance degrades when the panel is damaged. The thermal conductivity is around 0.007 W/mK, which is considered at the top value in terms of performance. This internal wall insulation method is indeed advantageous on locations where the house experience great heat temperature, that soars up to around 50 C.


The more advanced version of internal wall insulation method used in Pakistan is Aerogel. It is an insulation compound that is comparatively expensive than other insulation methods but has a good thermal conductivity which is about 0.013 W/mK. Aerogel is used on places where there is a thickness variable to look after but incorporate small area. Due to its compactness and expensiveness, they are purchased to cover windows reveals or other openings points inside a home, so that hot air and temperature cannot enter into the home that easily.

Phenolic foam

Phenomic foam is an all-rounder insulation method that can be used both internally and externally. The biggest advantage of Phenomic foam is its tag price, which is far cheaper as compared to Vacuum Insulated panels and Aerogel. As for the application, Phenolic foam can be placed using adhesive outside the wall, that can work as a good fire resistant compound. The thermal conductivity for Phenolic foam is around 0.022 W/mK.


Polyurethane has the tendency to be applied either through foam spray or using solid panel based application on various structure, both internally and externally. Due to it’s readily available in Pakistan as internal wall insulation methods, Polyurethane is extensively used in almost every department practically, whether its residential, commercial or industrial. The only side effect of using raw polyurethane is it’s highly combustible, but for achieving industrial safety bar, polyurethane is coated with fire-resistant chemicals which makes it safe to use for homes. It has a commendable thermal conductivity ratio, around 0.022 W/mK.


With the thermal conductivity value similar to polyurethane, Polyisocyanurate is the compound used as the internal wall insulation method in Pakistan. The best thing about Polyisocyanurate is it’s naturally fire resistant which reduces the extra cost for its application. For practical usage, Polyisocyanurate is foil coated with Celotex to have a maximum advantage for having an airtightness possibility in order to prevent heat radiation from entering into the home. It has the thermal conductivity equal to 0.025 W/mK.

Expanded Polystyrene

Expanded Polystyrene, due to its toughness and combustibility in nature, is commonly used as external wall insulation method, but can also be used for internal wall insulation. With thermal conductivity equal to 0.03 W/mK, Expanded Polystyrene helps the wall to get protected with heat and dry weather, but for preventing for burning or to make it fire resistant, a special type of compound is used to cater that in order.


With other internal wall insulation method used in Pakistan such as Glass, mineral, wool, and wood insulation, it is important to realize that these proven techniques really help improve the thermal conductivity of any structure, for both internally and externally.
