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.
Celotex XR4000 insulation boards provide the second layer solution for two-layer installations such as between and under rafters and joists, and between and over studs. This insulation is suitable for a number of applications, including:
Shelf life: please see the manufacturer’s date of expiry. Keep in a dry place, in the original packaging. Avoid excess heat or UV light exposure.
Wear eye protection, gloves and a mask. Take extra caution when using cutting equipment.
