Fire Performance

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 boards should be mechanically fixed to the parapet wall using the recommended through fixings. Fixing centres should not exceed 600mm. Fixings should be positioned at least 50mm from the top of the board, but not exceed 200mm. In the event that the roof deck is not supporting the bottom of the upstand board, additional mechanical through fixings should be used to compensate.

Mechanical fixings

AIM recommends Speedline DDS fixings or similar approved when installing this product. Ensure that the fixings penetrate the parapet wall by at least 25mm. These are available from SIG Fixings and other approved distributors.

Decoration

The external grade board can be decorated if required. The board does not require priming and can be painted with alkali resistant paints such as acrylics, chlorinated rubber, epoxy, PVA, PVC, polyurethane and silicate.
