Product Description
Celotex GA4075 Insulation Board 75mm is an easy-to-install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low emissivity foil facing. It is multi-purpose and can be considered for roof, wall and floor applications.
What is Celotex GA4075 Insulation Board 75mm? Celotex GA4075 75mm is a cost-effective insulation solution that offers multiple thermal insulation options without having any negative impact on its performance. It has a thermal conductivity of 0.022 W/mK and can be easily cut to shape and installed safely and easily.
The foil facing retains warm air and prevents it from passing through the board and reaching cold space, which is essential to prevent condensation and dampness. It is made from a rigid foam core with added blowing agents which have zero ozone depletion potential (ODP) and low global warming potential (GWP).
Features and benefits of Celotex GA4075 Insulation Board 75mm:
Excellent thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value.
Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
Easy to install – Celotex boards are light and rigid assisting with ease of transportation, handling, and fitting.
BBA certified – Celotex GA4000 has been assessed by the BBA as fit for use in defined roof, wall, and floor applications if installed, used, and maintained as set out in the certificate.
Celotex GA4000 achieves a BRE Green Guide Rating of A which can assist in demonstrating environmental performance in BREEAM assessments.

Do I need to use membranes when installing GA4075 below a concrete slab or screed?
Ensure that the PIR insulation boards are laid above a damp proof membrane (DPM). The foil facings of PIR insulation boards may be damaged by wet screed or wet concrete, allowing gas to escape that may weaken the floor topping, so its recommended that an additional vapour control / separating layer is used for protection over the PIR insulation boards once they have been laid, and prior to the screed or concrete topping being poured.
What Is A U-Value? In relation to insulating the home, a U-Value is the flow and loss of heat through the materials that make up the building itself, including bricks, flooring, roofing and windows. The U-Value is measured in watts at the rate of heat transfer. The important point to note is that the lower the U-Value is, the...
