| An intumescent expansion joint filler for gaps from 7 to 150mm
with a fire integrity of up to 4 hours.
Description
Gap Seal incorporates the very best quality open cell fire resistant
foam bonded to a unique high performance graphite intumescent material.
Achieves class '0' spread of flame as specified in British Building
Regulations. It does not flame but slowly degrades and expands to
leave an inert self insulating char.
Application
Gap Seal is designed for ease of installation. A cost effective
solution for stopping flexible gaps in fire rated building elements.
It can accommodate any gap from 7 to 150mm, even irregular joints.
Useful in cable trunking because it allows addition or removal of
cables without damaging the seal.
Product approvals
Tested following the principles of BS 476 Parts 20 and 22 (1987).
Product benefits
- Fire rated for up to four hours in both horizontal and vertical
joints.
- Easy to install.
- Very flexible.
- Usable in joints up to 150mm wide.
- Unaffected by water or moisture.
- Maintenance free.
- Lightweight.
Installation as a gap seal
Compress Gap Seal between fingers and push into place. Ensure the
foam core recovers and it is flush with the face of the joint. Gap
Seal can easily be cut using a sharp knife or a fine toothed hacksaw.
Installation as a trunking seal
Cut Gap Seal to fit tightly into the width of the trunking. Lay
the first piece below the cables. Any gaps greater than 6 to 8mm
should be filed with small pieces of Gap Seal. Further layers of
Gap Seal build up the seal until the trunking height is full. The
final top piece should fit tightly to ensure the whole seal is under
slight compression.
