Fire Performance

The impact resistant facing board complies with the performance requirements of Class O of the Building Regulations, is incombustible to BS 476 part 4, and is rated Class 1 Surface Spread of Flame to BS 476 part 7.

Installation

The boards should be cut using a TCT saw (ensure that FFP2 or 3 grade PPE is used to protect against inhalation of dust during cutting). The board should be fixed directly to the upstand wall using the recommended through fixings. Fixing centres should not exceed 600mm. Fixings should be positioned at least 50mm from the top of the facing board, but should not exceed 200mm. In the event that a roof deck is not supporting the bottom of the board, additional through mechanical fixings should be used to compensate.

MECHANICAL FIXINGS

AIM recommends Speedline DDS fixings or similar approved when installing this product. Ensure that the fixings are a minimum of 25mm longer than the overall thickness of the board. These are available from SIG Fixings and other approved distributors.

Decoration

Where required the facing board may be painted without any special priming using an alkali resistant paint or emulsion. Two coats of paint will usually give a satisfactory finish. Suitable paints are: Acrylics, Chlorinated rubber, Epoxy, PVA, PVC, Polyurethane and silicate.
