This Unilin PIR insulation board (formerly known as Xtratherm) is designed for high-performance insulation for use where maximum thermal resistance is needed. Manufactured with high-quality Polyisocyanurate (PIR) material, it is ideal for floors, walls, and roofs in both new builds and refurbishment projects. It minimises heat loss and ensures optimal indoor temperatures whilst reducing energy consumption.
Key Features:
Maximum thermal resistance reducing energy costs
Ensures optimal indoor temperatures
Durability: resistant to mould, fungi and rodents
Reduces energy consumption
Moisture resistance with foil facings to preserve performance over time
Applications:
Floors
Underfloor heating
General hnsulation
Walls
The foil facing on PIR insulation boards acts as a radiant barrier, reflecting heat back into the building. In the winter, it helps to retain heat, while in the summer, it reflects solar heat away from the building. This dual action helps maintain a comfortable indoor temperature and reduces energy consumption for heating and cooling.
