AF Brick: AF Systems' new fireproof brick

AF Systems' new AF Bricks are intumescent polyurethane sponge bricks designed for the infill of electrical and mechanical system crossings (electrical cables, cable trays, insulated and non-insulated metal pipes, plastic pipes, etc.).

Indicated wherever there is a need to create an easily removable and repositionable barrier, the AF BRICK are easily shaped to seal openings of different geometries, moreover, as the temperature increases (over 200° C) the AF BRICK begins the expansion process by forming a highly insulating fireproof mass which allows perfect sealing against cold fumes thanks to their permanent elasticity.

With AF Brick, installers always have a ready-to-use solution on building-sites

Firestop bricks are tested up to EI 180 for floors and EI 120 for walls (rigid/flexible) according to EN 13501-2: 2016. The tests were carried out according to the 1366-3: 2009 standard.

The product is sold in a parallelepiped shape in the size of 150x150x50 mm for the protection of combustible pipes of diameters up to 110 mm and for non-combustible pipes up to 108 mm and up to 40 mm of insulation.

AF Brick is suitable for the protection of cable trays both with rigid support (300x75 mm) and with flexible support (300x80 mm). The application of the product in large opening is certified up to 550x1050 mm.
