PIROSILICON 240 is a non-flammable and self-adhesive silicone mass, intended for restoring the fire resistance of rigid walls with expansion joints. It is used to fill expansion joints together with PIROFOAM 240 or mineral wool in rigid walls made of concrete, aerated concrete, reinforced concrete, bricks or blocks with a density of not less than 600 kg/m3. The silicone mass can be applied directly to PIROFOAM 240 G fire-rated expanding foam, PIROFOAM 240 W fire-rated expanding foam or mineral wool according to EN-14303 or EN-13162 used as a gap filling material.

PIROSILICON 240 is intended for fireproof sealing:
•    Horizontal expansion joints in building partitions constituting fire partitions with a possible displacement of up to ± 7.5%
•    Vertical expansion joints in building partitions constituting fire partitions with a possible displacement of up to ± 7.5%

Works with silicone should be carried out on a clean, degreased, dry surface at an ambient temperature above +5°C, with proper ventilation.
