Technical Features

AF FLEX JOINT is suitable for linear sealing subject to movement, as they are compressible from their initial size. The product’s expanding movement range relates to its pre-compression degree and overall movement.
AF FLEX JOINT  is a spongy parallelepiped which is easily compressible to seal structural joints between adjacent compartments which confine the fire to its point of origin.
The product's permanent elasticity (sponge effect) seals against "cold smoke". When exposed to fire at a temperature that exceeds 200°C, AF FLEX JOINT and physically modifies itself to form a highly insulating non-combustible mass.

Specification

Supply and application of AF FLEX JOINT fireproof joint covers, made of polyurethane-based intumescent material, for EI 120 protection of linear structural joints. The joint covers can be assembled (using adhesive-coated aluminium tape) to obtain the required width depending on the size of the structural joint up to a maximum of 30 cm.

Application Method

1. Measure the dimensions of the joint to be sealed;
2. Calculate and apply the number of  AF FLEX JOINT covers required to completely seal the opening, taking into account the desired degree of compression/expansion;
3. Join the joint covers head-to-head using adhesive-coated aluminium tape;
4. Create a "spider's web" wire frame on the side exposed to the fire by placing metal plugs (e.g. 8x60 mm) on both sides of the opening with a pitch of 25 cm.

Reason to choose AF Flex Joint
