Description

Celotex CW4000 is a versatile polyisocyanurate (PIR) insulation board designed for partial fill cavity wall applications, offering outstanding thermal performance with a conductivity of 0.022 W/m.K. Its low emissivity foil facing enhances thermal efficiency by reflecting heat within sealed cavity air spaces, helping achieve target U-values with reduced insulation thickness.

Featuring squared edges and a size tailored to fit standard wall tie spacing, these rigid boards simplify installation while ensuring a precise and effective fit within cavity wall systems.

Certified by the British Board of Agrément (BBA certificate 16/5343), Celotex CW4000 is approved for use in partial fill cavity wall applications, provided it is installed and maintained according to the guidelines. This certification underlines its reliability and suitability for a wide range of construction projects.

Whether you’re aiming to improve energy efficiency or meet stringent building regulations, Celotex CW4000 delivers exceptional performance in a practical and easy-to-use solution, making it a trusted choice for cavity wall insulation.
