Polyisocyanurate (PIR) Insulation Boards: How Do They Work?

Having a long-lasting roof is a dream for most property owners as a cost-saving solution. Recently constructors are choosing insulation boards for their long-term roofing needs. The need for durable, inexpensive, and quality insulation boards has led to the increasing popularity of  Polyisocyanurate (PIR) insulation boards.

Also called ISO or Polyiso, PIR is a form like a thermoset plastic used in insulation boards to protect against external extremities. PIR’s super inherent qualities make it ideal for providing maximum value for insulation boards popularly used on roofs and walls.

How PIR Insulation Boards work

The PIR insulation board comprises a polyisocyanurate insulation core placed in the middle of high-quality aluminum foils to create a light, long-lasting, and high-quality insulation board. 

Why Use Polyisocyanurate( PIR) Insulation Board

Compared to other insulation board materials on the market, PIR has gained much popularity due to its myriad benefits. Listed below are reasons why you should opt for PIR Insulation Board.

Provides maximum insulation

The Polyiso material contains a heat conductivity value of 0.022, making it one of your roofing needs’ best performing insulation material. Besides,  the heat and pressure-resistant quality also help ensure your roof is well protected against any extremities, therefore extending its shelf life.

Ability to withstand humid atmospheric conditions

Most lightweight insulation boards absorb moisture, which ultimately affects the boards’ insulation value and weight. However, PIR insulation water-resistant quality enables it to maintain its weight, shape, and inherent value over a long time.

Resistance to heat

The innate ability to withstand heat is one of the best qualities of the PIR insulation board. This super quality makes it one of the most preferred roofing insulation materials in the event of a fire outbreak.  Similarly, being a firm thermoset enables the PIR insulation board to save energy as it can self-regulate itself during the hot and cool season. Moreover, the PIR insulation board helps keep your home with the desired temperatures, i.e., warm during the winter and cool during the summer season.

Resistance to pressure

Despite its thinness and lightweight, the PIR insulation board can withstand pressure; therefore, you can comfortably walk or stand on your roof during installation and not worry that it will break or lose its value due to surface damage.

It is thin and light

The PIR insulation board  is very thin and  light, weighing approximately 32 kg/m³; therefore, when installing it, you need not worry about your structure collapsing due to excess pressure 

Highly Versatile 

The PIR can easily be combined with other materials to provide maximum value for your roofing needs.

Durability

Once you install a  PIR insulation board, you have the assurance that it will last for a long time. As a result, you do not have to worry about the costs of carrying out re-installations.

It is safe and environmentally friendly

The  PIR insulation boards help to reduce the emissions of carbon dioxide into the atmosphere. Therefore helps in preventing environmental degradation caused by harmful gas emissions.

Similarly, the PIR material is safe to use as it does not irritate the skin when in contact.  It is light and easy to cut; thus, you can easily install it by yourself.
