25mm PIR / Thermal Sheathing Board – 2400x1200x25mm

Optimise your building’s thermal efficiency with the high-performance 25mm PIR / Thermal Sheathing Board – 2400x1200x25mm. This premium insulation panel is specifically engineered to provide market-leading insulation for modern construction and renovation projects. Designed to significantly reduce heat loss and enhance internal climate control, this rigid thermal insulation board ensures long-term energy savings while maintaining a comfortable indoor environment.

Each high-specification insulation sheet features a rigid polyisocyanurate (PIR) core that delivers exceptional thermal conductivity. Boasting an impressive U-value of 0.022W/mK, the 25mm PIR / Thermal Sheathing Board – 2400x1200x25mm stands as a highly dependable and efficient barrier against heat transfer, making it a critical component for meeting stringent thermal regulations.

Multi-Purpose Insulation Applications

The structural versatility of the 25mm PIR / Thermal Sheathing Board – 2400x1200x25mm makes it an excellent choice for multiple areas across the entire building envelope:

• Pitched Roofs: Ideal for over, under, or between-rafter insulation layouts to create an airtight and highly secure warm roof structure.

• Framed Walls: Perfect for application within timber framing, steel framing, or masonry cavity walls to eliminate thermal bridging and cold spots.

• Floors: Highly suitable for solid concrete floors or suspended timber joist configurations, offering a durable, dense base beneath screeds or floor finishes.

Key Features and Performance Benefits

• Premium U-Value Performance: Features an incredibly low thermal conductivity rating of 0.022W/mK, guaranteeing outstanding heat retention and thermal isolation.

• Lightweight and Ergonomic: Each PIR board is inherently lightweight, allowing for effortless handling, quick positioning, and safe on-site lifting by a single installer.

• Simple to Cut and Route: The rigid foam structure is exceptionally easy to cut to size using a fine-toothed hand saw or a sharp utility knife, facilitating precise edge matching and minimal waste.

• Market-Leading Brands: To maintain consistent delivery speed and supply continuity, the product supplied will be from a top-tier market leader, including Celotex, EcoTherm, Unilin, Recticel, or an approved equivalent.

• Exceptional Structural Stability: The dense, rigid polyisocyanurate core offers high compressive strength, resisting deformation over decades of constant structural loads.

• Generous Size Coverage: With standard sheet dimensions measuring 2400mm by 1200mm, each board offers broad wall and floor coverage, drastically reducing installation time and the total number of open joints.
