25mm PIR Rigid Insulation Board – 2400mm x 1200mm
Our 25mm PIR Rigid Insulation Board (2400mm x 1200mm) is a high-performance thermal insulation solution designed for use in walls, floors, and roofs where space-saving and efficient thermal performance are essential. With excellent compressive strength and low thermal conductivity, these boards are ideal for both new builds and refurbishment projects.
Product Features/Specifications:
- Rigid polyisocyanurate (PIR) foam insulation board
- High thermal performance with low λ-value
- Foil-faced on both sides for improved insulation integrity
- 2400mm x 1200mm board size for easy handling and installation
- 25mm board thickness
- Suitable for floors, walls, pitched roofs, and ceilings
- Lightweight and easy to cut and fit
- Complies with relevant building regulations
Detailed Product Benefits:
The 25mm PIR board offers reliable thermal resistance while maintaining a slim profile, making it particularly useful in tight spaces or where thinner insulation layers are preferred. The foil facings act as radiant barriers, enhancing insulation performance. Lightweight yet durable, these boards are simple to install and suitable for a wide range of building applications.
Applications and Versatility:
Ideal for use in:
- Solid floor insulation
- Between and under rafters in pitched roofs
- Internal wall linings
- Timber and steel frame construction
- Ceilings and loft conversions
Can be installed using mechanical fixings or suitable adhesive systems depending on the application.
