Celotex CW4000 Cavity Wall PIR Board

Celotex CW4000 Cavity Wall PIR Insulation Board offers an environmentally-friendly solution for enhancing thermal efficiency in buildings. Made from polyisocyanurate (PIR), a sustainable insulation material, it boosts energy performance while minimising environmental impact. Designed for straightforward installation, the board delivers exceptional thermal properties and features a low emissivity foil facing. Available in thicknesses from 40mm to 100mm, it is perfect for partial-fill cavity wall applications, offering both efficiency and sustainability.

Key Features:

• Outstanding thermal performance with a thermal conductivity of 0.022 W/m.K, allowing for a thinner insulation layer to meet target U-values.
• Low emissivity foil facing enhances thermal performance in sealed cavity air spaces, improving the overall U-value.
• Lightweight and rigid, making the boards easy to transport, handle, and fit. They are sized to match standard wall tie spacing, ensuring effortless installation.
