ENVIROGRAF FIROBLOK fire protection foil 40–45x300mm for non-combustible pipes, grey/aluminium

Firoblok Thermal is a foil-coated, insulating, and intumescent fire sleeve developed for use around non-combustible pipes that pass through fire-rated floors or walls. Designed for ease of use, Firoblok Thermal is flexible and simple to install: the pipe can either be pulled through the sleeve, or the sleeve can be cut open, wrapped around the pipe, and sealed with the integrated tape. The sleeve must be installed to the full depth of the wall or floor and completed with Envirograf AM Fire Mastic (p58) to ensure a proper seal. In addition to its fire protection properties, Firoblok also provides effective acoustic insulation and helps prevent corrosion on metal pipes. The product is a pre-approved solution under the Danish Building Regulations (BR18) and has been tested in accordance with EN 1366-3, achieving an EI 60 fire resistance rating at DBI.
