Celotex boards are often PIR boards with foil facings to improve insulation levels. Celotex boards are made using a lamination process, where aluminium foil facings are flued together in a laminator, with an added blowing agent which causes the adhesive to expand into foam. The product is then cut into boards.

What is Celotex used for?

Why does Celotex have foil?

Celotex GA4000 insulation boards are manufactured from polyisocyanurate, and have low emissivity foil facings to aid with reducing heat transfer. The R-value denotes the resistance to heat flow – the higher the R-value the more insulating the product is.

Can Celotex be used outside?

Celotex insulation boardsmust be protected from prolonged exposure to sunlight and stored dry, flat and raised above ground level (to avoid contact with ground moisture). Where possible, packs should be stored inside. If stored outside, they should be under cover, or protected with opaque polythene sheeting.
