SIDERISE LGS Linear Gap Seal – Facades (formerly Lamathern CW-GS)

More Information:

SIDERISE LGS is a third party certified intumescent strip designed to seal junctions between building elements to prevent the spread of fire and smoke, providing up to 240mins fire resistance.

Part of the Certifire approved range of linear gap seals, these intumescent seals comprise a flame retardant acoustic foam core with an intumescent coating. In fire conditions they maintain a close fit to prevent the spread of cold smoke. On the fire side the foam compresses and is replaced by the expanding intumescent, preventing rapid fire spread into the joint. The non-fire side retains flexibility accommodating heat induced structural movement.
