The upside of using metal insulation fasteners is their dependability to continue to function in the event of a fire; the downside is that metal is a good conductor of heat and can provide a thermal bridge through the insulation, resulting in potential heat loss at fastening positions. In contrast, metal fixings maintain the stability of the boards in the event of a fire. Metal fixings comply with BS EN 13501 as a Class A1 non-combustible fastener. Class A1 fasteners will not contribute to a fire at in any stage nor will they present a smoke hazard. You can upload: image, audio, video, document, spreadsheet, interactive, text, archive, code, other. It is common for pragmatic designers to specify an insulation fastening system that combines the attributes of both plastic fixings and steel anchors. In external wall insulation systems for low-rise buildings, the designer may prescribe the use of the more thermally efficient plastic fasteners, supplemented by using fire-safe mechanical fixing per board. Select the Appropriate Type of Non-Combustible Mechanical FixingsAvoid fixing into mortar joints. If using chemical resin anchors, always follow the manufacturer’s instructions.

Non-combustible fixings for fastening insulation to concrete soffits Drill the stud home so that the collar of the stud is just protruding out of the hole and then leave it to set for an hour. Threaded stud drilled into the chemical capsule and left to set The use of such synthetic fasteners helps to fulfil the objective of retaining the utmost insulation values of a building by mitigating potential heat loss at fastening positions.
