PIR insulation boards are made of Polyisocyanurate, and they are hard boards that are used as insulation. They are made as an improvement over PUR (polyurethane) boards, and they are thermoset plastic that is made by taking particles and foam insulation and blowing them before they make them into solid boards. Both products are similar, but they have different chemical structures, and PIR boards offer greater thermal insulation.
Advantages of PIR Insulation Board
There are advantages to using a PIR insulation board. First, they offer excellent thermal performance, so it is difficult for heat to pass through. In addition, they can be made with foil on the face, which helps to reduce the ability of moisture to pass through. Because of these properties, you can use a thinner board and still get excellent performance. This will leave more floor space. These boards also last longer, and they are able to hold their shape and durability for a longer time. They can be fire resistant, and they are easy to install.
Where to Use PIR insulation Board
If you choose standard POITR insulation boards, they can be used in different parts of buildings. It is common to install them in a pitched roof between the joists, but they are also installed with a flat roof and provide insulation between the roof and the home. They can be easily cut and used as wall insulation, and you can use them under floors and above ceilings. They are easy to install, and they offer thermal protection, so they are commonly used.
PIR Insulation and Fire
A common question that people ask is, “Is PIR insulation safe?” It is commonly used in many types of buildings, and the different PIR products will have ratings for fire safety, depending on how it is manufactured. It is not normally flammable, but some PIR insulation can release smoke that is toxic when it is burned. The key is to check the fire rating and make sure that it complies with the codes of your building project.
PIR Insulation and Moisture
People also want to know whether or not PIR insulation boards can get wet. It depends on the type you choose. Standard PIR boards should not get wet, but you can get them with foil facings, and this type is designed to handle moisture. If your PIR insulation boards get wet, you should not install them until they are completely dry.
