PIR insulation boards, also known as rigid polyisocyanurate boards, are employed throughout all construction areas. Compared to previously utilised polyurethane (PUR) boards, they provide many glaring benefits. To further inform our consumers about PIR Insulation and all of its advantages, we have put together this guide.
What Are They?
The thermoset plastic used to make PIR, or polyisocyanurate, is created by blowing agents as foam insulation before being moulded into solid boards. Even though PIR and PUR are made from comparable materials, PIR has a different chemical makeup. For several reasons, PIR insulation boards have grown popular in the industry.
They provide a high degree of thermal performance, preventing heat transfer. They may also have foil facings to prevent moisture from passing through. When put inside, PIR insulation boards can function well while being thinner than conventional materials, giving you more floor space.
PIR insulation boards are extremely durable, maintaining their strength and form throughout time. They may be constructed with fire-resistant qualities depending on the manufacturer. Builders only need to trim the boards to size, making them simple to work with and install.
Where Can It Be Used?
Across a building, standard PIR insulation boards can be employed. It is suitable for use in pitched roofs when installed between the joists. In a heated flat roof, they can be put to provide a strong and reliable insulating layer. They may be trimmed to size and put in between studs to be installed as wall insulation for timber frames. They can also be utilised in the space between floor and ceiling joists.
PIR insulation boards provide a high degree of thermal support and quick and simple installation, making them suitable for most conventional insulation applications. As previously mentioned, specialised PIR Insulation materials may be utilised as dry lining, flat roof insulation, and cavity wall insulation. PIR insulation provides effective thermal support and may be applied throughout a structure.
Is It Flammable?
Although PIR Insulation normally has a low fire rating, you should always verify the manufacturer’s paperwork to confirm this. Despite not being combustible, PIR insulation may emit poisonous fumes when it burns, which should be considered in construction projects. Any building project should put fire safety first, and you should ensure that all materials have acceptable fire performance and that flammable elements be avoided.
Can It Get Wet?
Unless particularly created for moisture resistance, PIR Insulation should be maintained away from water and have foil facings. If boards become wet, they must completely dry off before being fitted inside a structure. Solid PIR insulation shouldn’t absorb much water, especially when compared to alternative insulation choices such as mineral wool.
