Safety Data Sheet Celotex XR4000 should not be used in the external walls of buildings over 11 metres in height. Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility should be used in buildings of that height. ...
Installing thermal insulation below a concrete deck is not usually an option, so rigid insulation is installed above the deck. Lightweight, rigidpolyisocyanurate (PIR) foam insulation boards(such asCelotex GA4000andXR4000), are among the most thermally efficient, commonly available insulation materials...
Rigid, lightweight, polyisocyanurate (PIR)foam insulation boards (such asCelotex GA4000andXR4000) are among the most thermally efficient, commonly-available insulation products on the market. Fixed over the rafters of a pitched roof, they can help to achieve the required U-value in just a singl...
Arigid polyisocyanurate (PIR) board can be installed between the joists(Celotex GA4000andXR4000can be considered) provided the insulation is cut accurately and fitted carefully to avoid air gaps. Thinner polyisocyanurate (PIR) foam insulation boards, such asCelotex TB4000, can be considered for the...
(PIR)insulation boards can accommodate typical storage loads without compressing. Timber boarding should be laid over the boards to provide protection and maintain their performance. Screw fixings are typically all that is required to secure a product likeCelotex GA4000orXR4000in position above the ...
