Rigid non-flammable perlite foam insulation board.
Biologically inert, Eraboard insulation boards do not emit gases or toxic substances, and do not allow static electricity to build up. Eraboard's main constituent is perlite, a naturally occurring volcanic stone found in surface beds that is so environmentally safe it is even used to filter drinking water. Through a high-tech manufacturing process, perlite is ground into granules, expanded and then mixed with cellulose fibres, glass fibres, binders and special additives. The resulting conglomerate is formed into sheets of varying thickness which are cut into boards with constant dimensions. The range also includes the Eraboard S version, whose upper face is coated with blown bitumen and covered with burn-off film to ensure that torch applied bitumen-polymer membranes are easier to bond to the board and adhere more effectively.
Complies with BS EN 13169.
