Firespray® consists of slag wool, with hydraulic and inorganic binders. It is supplied in the form of light ﬂakes.
The thickness of the fire protection coating varies between 21 and 69 mm.
Beam height must be at least 120 mm
The assembly involves placing M48 spacers directly on the floor beams at right angles with a maximum spacing of 600 mm. Screw-fix an expanded metal sheet and apply Firespray® to the desired fire protection rating.
Firespray ® fibres are spray-applied using a spraying machine. The fibres are pressure-fed through a hose. Water-fed nozzles are placed around the hose outlet to wet the product before it is sprayed onto the substrate. The fibres are then fed into a spray gun used to apply the Firespray ® mixture.
he thickness of the sprayed layer will be defined according to the required fire resistance rating.
