Firestop blocks INTU FR BRICK are made of a material that expands under the influence of temperature above 140°C. Intumescent inserts close the hole during fire, preventing the spread of fire and smoke.
- fire resistance class up to EI 120
- for use in walls and floors
- available sizes: from Ø50mm to Ø200mm
- possibility to protect the penetrations with/without cables
INTU FR BRICKs are installed in openings in walls or floors for protecting cable penetrations (cables ≤ 21mm, cable bundle up to 100mm), as well as openings alone without cables. The intumescent material that swells during a fire fills the hole completely, preventing fire and smoke from entering adjacent rooms. It is possible to run cables through an already installed block in the hole.
The wall must be at least 150mm thick and have concrete, cellular concrete structure or masonry structure, with a minimum density of 600kg/m3
The floor must be at least 150mm thick and have concrete, cellular concrete structure or masonry structure, with a minimum density of 1700kg/m3
