AIS FR Mortar- FP 305 is a dry white powder consisting of inorganic compounds and perlite.
When mixed with water, the compounds form a highly thermally insulating fire sealing compound to prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations. It will also maintain the acoustic design performance in walls and floors.
FP 305 expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures. It is easy to sand or drill. The compound dries to an off-white color which may be painted.
The sealant has undergone tests to BS EN 1366-3 for fire protection joints and tested in accordance with ETAG 026-2 to demonstrate its suitability for use in internal conditions.
Classified in walls and floors of concrete, brick, gypsum etc.
