Removable and environmentally friendly fire-resistant and airtight solution for limited cavity width (up to 50 mm).

The Firetight®-Firetape is in fact a modified Airtape that is produced as fire-resistant. It is surprisingly easy to realize both an airtight and a thermal seal between building components in one operation, which is then fire-resistant for 60 minutes. Patented Firetight®-Firetape consists of a vacuumed strip of mineral wool wrapped in a vapour barrier PE-foil, supplemented with intumescent tape and is available in various lengths. After installation, the wool expands and Firetight®-Firetape completely fills out the entire gap between the construction parts. The realized connection is thermally insulated, airtight and fireproof.
