Is Celotex dust harmful?
Considering this, is kingspan dust harmful?
Inhalation: Dust is non-hazardous. Dust from timber facings may cause respiratory irritation. As with all cutting procedures it is recommended that a disposable dust mask be worn. Where dust is generated through mechanical cutting in confined spaces, it is recommended that extraction be used.
Beside above, is Celotex a Vapour barrier? Insulation vapour barrier instructions Extruded polystyrene (XPS) has good vapour resistance, while most other insulation boards (polyurethane et al) have aluminium facings which make them impermeable. I use Celotex or Kingspan insulation boards which are foil faced, and then I cover them with separate plasterboard.
Considering this, what is Celotex made out of?
It is made by a lamination process, formed between aluminium foil facings that are glued together in a continuous laminator, where the 'adhesive' is a mixture of MDI and polyol. An added blowing agent causes this adhesive to expand into foam that hardens and is cut into manageable board sizes.
When did Celotex stop using asbestos?
