For the longest time, polyurethane foam has been in use for the insulating buildings. Currently, polyurethane foam is used to insulate larger regions like foundation walls. It can also be used on smaller levels like insulating door and window perimeters, et cetera. There are multiple advantages to using polyurethane foam.

If you know how insulation works and the materials used for insulating, you must have heard of the R-value. R-value is a measurement unit that reflects the heat transferability of a material. The calculation of the R-value depends on the thermal conductivity and thickness of the material that is being checked. The more the value of R is, the higher levels of insulation the material will provide.
Polyethylene foam insulation has an R-value that is higher than other insulation types. The R-value of polyurethane foam is 3.5 – 4, while the r-value in the case of EVA foam, r-value is 1.515. If you wish to purchase EVA foam, check out EVA foam Malaysia.
Waterproof and airtight
The reason polyurethane foam is used for making envelopes is that it is airtight as well as waterproof. It also provides seamless insulation. Since there is no gap between the substrate and the insulation, polyurethane foam can act as a vapor barrier and act as an external insulator as well. If you choose to use foam insulation, you will save a lot on expenses. The cooling and heating of the building will need less amount of energy, and there will be no need to install house wrap between the exterior walls and drywalls.
Moisture and mold resistance
Polyurethane is an inert plastic. It does not absorb water or moisture. Thus, it does not promote the development of mildew or the growth of any microorganism. It also protects other building materials from mild water damage and mold by foaming a water barrier that is 100% waterproof.
Good dimensional stability
A lot of insulation materials are used in the business, like cellulose and wool sag over time. This tendency can lead to the formation of thermal bridges in regions where enough insulation is not available. If this happens, the susceptibility of the building towards heat loss increases. Polyurethane foam insulation is very well recognized for its dimensional stability. Once it has been cured, the volume does not decrease or increase no matter which type of weather condition the foam gets exposed to.
Easy to use
Possibly the biggest advantage in the case of polyurethane foam is that it’s very easy to apply and use. It easily gets adhered to most materials that are used for building exteriors and interiors like metals, wood, concrete, etcetera. It allows the mold to fit perfectly into the shapes and gaps. All one needs is a foam gun to apply this insulation. Therefore, this product can fill up the smallest gaps, prevent messages and be very easy to handle.
