- For the sealing of linear joints
- Elastic, single component silicone, for a perfect seal against the spreading of smoke, toxic fumes, heat and flames through walls and compartment floors
- To be used combined with rock wool, in order to obtain EI fire resistance values
- Excellent elasticity
- Optimal adhesion, even on porous materials such as concrete, gypsum plasterboard, etc.
- CANNOT be painted over
- Resistant to ageing and weathering, good resistance to UV rays, odourless
- Not recommended for plastic materials such as PE, PP, PTFE, or for sealing areas constantly in contact with water, or for horizontal wall joints, glueing of mirrors, marble or natural stone
- High resistance to fire, up to 240 minutes (depending on the type of joint)
- Can be used for joints of any lengths
- Long fire resistance times even in walls only 100 mm thick – other brands would require larger thicknesses which are usually not found on a building site, and that invalidates certification of those products
- Can be used not only for floors, but also for walls made of concrete, gypsum plasterboard and of solid and hollow bricks, as long as they have a minimum thickness of 100 mm
- Thanks to its elasticity, it adapts easily to the different geometries of the joints
- Simple to handle and to apply: can be applied using a classic silicone extrusion gun
- Yield of one cartridge: ca. 3 m (for a 10 x 10 mm seal)

Observe the positioning specifications in each case
Because the material is not intumescent, it is not suitable for the fire-retardant sealing of joints containing pass-through elements (pipes, cables etc.). Use other Fireseal systems
