Description
The 100mm Celotex GA4100 PIR Insulation Board (2400mm x 1200mm) – Pack of 24 is a high-performance rigid insulation solution designed to improve thermal efficiency across floors, walls, and roofs. Manufactured from polyisocyanurate (PIR), these lightweight insulation boards provide excellent heat retention while helping to reduce cold bridging and energy loss in residential and commercial buildings.
Featuring a low-emissivity silver foil facing, Celotex GA4100 enhances thermal performance when installed in sealed cavity air spaces, helping achieve lower U-values. The boards have a thermal conductivity of just 0.022 W/mK and deliver a strong R-value of 4.5 m²K/W, making them an effective choice for modern insulation requirements.
Celotex GA4100 boards contain environmentally friendly blowing agents with zero ozone depletion potential (ODP) and are rated A in the BRE Green Guide, supporting sustainable construction practices. Their rigid, lightweight design allows for easy handling, cutting, and installation on-site.
