BCO / FSK Foil

Bright Class-O (BCO) aluminium foil is reinforced with bidirectional glass fibre scrim. FSK is a 7μm aluminium foil facing, reinforced with glass fibre scrim and comes with a polythene vapour barrier, mounted to Kraft paper. Foil-Scrim-Kraft (FSK) is more durable than simple foil facings and is classified to a Class 1 fire rating. These products are available as a reflective facings on most insulating products and is far more durable than standard foil facings.
