Compressible fire-resistant linear joint seal for vertical and horizontal applications.
The Quelfire QI Intufoam Linear Gap Seal provides reliable fire stopping at the junctions of compartment floors and walls or between structural elements. This graphite-faced, compressible foam solution expands in fire conditions to reinstate compartmentation, ensuring up to 120 minutes of fire protection depending on orientation and gap width. Lightweight and dry-fitted, it is ideal for installation in linear gaps without the need for additional sealants or mechanical fixings.
