PIR insulation is a popular choice when it comes to choosing insulating material. It offers excellent insulating properties and several other advantages that help it stand out from other options. Find out why PIR often makes more sense compared to PUR and other types of insulation.
What Does PIR Stand For?
PIR stands for polyisocyanurate. It is a type of polymeric material that includes a combination of polyol and isocyanates. It is manufactured using a chemical reaction.
When the liquid polyols are combined with the isocyanates, a wet, tacky type of foam is created. The foam hardens and is used for different applications, including insulation. Some of the advantages of PIR include:
- Superior insulating properties
- Increased density
- Lightweight material
- Versatile options
Alternatives to PIR include PUR and EPS insulation. Compared to PUR and EPS, PIR has lower thermal conductivity. The thermal conductivity of a PIR panel is about 0.022 W/mK, which is lower than any other type of insulation. The low thermal conductivity means that PIR insulates better.
PIR Is Dense and Durable
The low thermal conductivity of the PIR panels is partially due to the density of the panel. The density of the panel also makes them fire-resistant, moisture-resistant, and pressure resistant.
The fire resistance of a PIR panel can hold up to fire longer compared to other types of insulation. These panels are less likely to crack or break under pressure.
PIR Is Lightweight and Easy to Work With
The density of PIR boards allows you to use thinner boards while achieving the same results. Using a thinner board means that the panels are likely to weigh less, which makes them easier to work with.
The typical PIR board weighs about 32 kg/m3. Yet, it is durable enough for use as insulation on flat roofs. The insulation on a flat roof must retain its shape after someone walks across it. PIR panels can withstand the weight of a grown person, making them suitable for use in more locations.
PIR Is a Versatile and Affordable Solution
PIR tends to offer greater flexibility compared to other forms of insulation. It can be engineered to suit a wide range of applications. It also provides a cost-effective option for most projects, as it is lighter and easy to install, which can cut down on material and labour.
If you want an effective thermal insulator at an affordable price, PIR may offer the best value. Consider using it wherever insulating boards are needed.
