Houses will always lose heat; heat loss will not only harm your comfort levels but will also make a dent in your pocket and the planet. This is where Celotex GA4100 100mm comes in. 100mm Celotex is the most popular Celotex insulation thickness on the thermal insulation market. It is a high performance, versatile insulation solution, which can be used for roof, floor, wall and timber joist applications.


The 2.4m x 1.2m boards are manufactured with a specially designed blowing agent that has a low potential to cause global warming. This is demonstrated in the fact that the boards have zero ozone depletion potential (ODP) and low global warming potential (GWP). What's more, 100mm Celotex PIR boards showcase low-emissivity foil facings on either side which increase their thermal performance in sealed air cavities; producing a superior U Value to other insulation solutions on the market with a thermal conductivity of just 0.022 W/m.K.

Celotex GA4100 Insulation Storage & Handling

As they are super light and portable, 100mm Celotex boards can also be handled and transported easily; making them a doddle to install. If you need to store 100mm Celotex insulation boards for a while before installation, you should choose a cool, dry space.

Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, pop them on a level surface and under a protective cover, just for good measure.
