Celotex XR4000 is a high performance, rigid polyisocyanurate (PIR) insulation material, suited for use with wall, floor and roof insulation systems. This PIR insulation is manufactured using a blend of blowing agents that have zero ozone depletion potential and therefore a low environmental impact and global warming potential (GWP). Celotex XR4000 helps to maintain a thermal envelope around the entirety of the building, working to prevent thermal bridging and cold spots. Celotex XR4000 is BBA Approved and creates a durable, long-term solution that will ensure energy-saving benefits.
Celotex XR4000 has low emissivity aluminium foil facings to offer improved thermal performance. The insulation is easy to handle and can be cut to fit.
