Intumescent gap seal for the tops of walls.
Flexible, water resistant, intumescent linear gap seals that expand when exposed to heat. They provide a versatile means of sealing junctions between building elements against fire penetration.
The compressible foam core accommodates different joint widths to allow for structural movement whilst additionally meeting requirements for cold smoke seal, thermal and acoustic properties. Standard sizes are available to suit gaps up to 150 mm and to provide either a two or four hour fire rating to BS 476-20. The material can also be used as an effective, adaptable fire stop inside cable trunkings; allowing for the installation of further cables.
