Before we can go ahead and understand various types of liquid-based insulation in Pakistan, a little disclaimer is due to follow in this article. There is no liquid-based heat insulation in Pakistan that existed similar to the elastomeric chemical used as heat proofing in Pakistan. Instead, when we say liquid-based, it only comes in foam structure, which is applied through a high power spray equipment. The heat insulation in Pakistan is a highly popular industry which needs more information on various types of foam-based heat insulation in Pakistan as explained below:
Considered a low-cost polymer with has the most a very high insulation value over little thickness of the material, it is extensively used as liquid-based heat insulation in Pakistan. When we referred to liquid-based, it most probably comes as foam-based which can be applied with the help of pressure spray equipment. Polystyrene comes in a hard shape object but can be broken down into foam for better application. To properly apply this heat insulation in Pakistan, its usually applied on area which is partially constructed as a compound used for making sandwich sections into the material. In practice, the Polystyrene is made from synthetic hydrocarbon polymer and can be labeled as monomer styrene.
As dedicated heat insulation in Pakistan used over roof and foundation, Polyisocyanurate is composed of thermoset plastic which can be extracted as a foam structure. By using around 102mm of thickness, Polyisocyanurate can have around R-24 for R-value. A relatively good heat insulation material used in Pakistan, Polyisocyanurate is used as a sandwich material used for foundation and unfinished walls. Since its made from the plastic compound, its application requires extensive care, such as proper safety equipment as an inhaler and proper protective gear. Using a fire-resistive layer after its application is also required since Polyiso is highly combustible.
Polyurethane is a compound made from organic polymers which are adjoined by carbamate links. Usually, the Polyurethane heat insulation is made is a thermosetting polymer, it cannot be melted with applied high temperature. Keeping this condition in view, polyurethane insulation is considered as one of the most used heat insulation material in Pakistan in any form, including liquid base, foam, or solid. Mostly, Polyurethane insulation is applied over the roof since its naturally a bad conductor, noncombustible and cannot absorb water. With every element works to the betterment for having solid heat insulation used in Pakistan, Polyurethane is used for any area where insulation is required.
Phenolic as similar to polyurethane is a thermosetting polymer used for molding and insulation of material. As for practical usages, Phenolic is relatively near heat insulation in Pakistan which can be used as liquid-based foam spray over hard to reach places. As a class of phenol, phenolics are highly combustible, hence it’s required that proper protective material is applied to protect it from the adverse effects of fire and another unwanted element. The good thing about Phenolic is that it’s cheap as compared to polyurethane compound but scarcely found as heat insulation in Pakistan.
Cementitious is foam-based insulation which is mixed with cement and thermal polymer to find against the high temperature. Usually, its use over the roof and any compound which is made of concrete, cementitious material is applied through a high powered spray which helps to reach the material on hard to reach places. Synthetically, cementitious insulation is made from magnesium oxide as a compound that relatively high R-value, similar to the fiberglass heat insulation in Pakistan. The good thing about cementitious insulation is that it can be applied openly above any concrete surface, whether it’s considered as finished or unfinished.
There is a huge potential for using liquid-based heat insulation in Pakistan because of its easy usage, high insulation value, and health-related safety, foam-based heat insulation comes a long way in protecting ourselves from high temperature, especially for people in Pakistan, where summers are usually considered as harsh. Thanks to various solutions at our disposal such as heat insulation in Pakistan as well as heat proofing chemical applications, security from high temperatures is not possible without spending a lot in electricity bills each month.
