Fire-resistant joints/flanges
Called a fire-resistant Flange or Joint or even a fire-resistant Cord, this product is made of rock wool covered in flexible glass fibre and can connect all kinds of joints – whether straight, curved or in different planes – without discontinuity.
Its elasticity means it can follow all the deformations of the joint, ensuring it is permanently sealed against smoke and fire.
Used alone, the flange provides 2 hours of fire resistance.
Used in combination with “B” sealant, it gives you 4 hours of fire resistance.
Several sizes are available, from a 20 mm to a 70 mm diameter.
