Tenmat’s RTF and RRF Roof Tile/Ridge are roof cavity firestop products and are manufactured from low smoke zero halogen intumescent material. They are designed to provide fire resistance performance between roof/ridge tiles and the party walls or spandrel panels below the roof covering, which separate different properties within roof spaces or provide lines of compartmentation.

The RTF and RRF are manufactured from a flexible highly intumescent material allowing it to be provided in a roll format, they are also covered with a protective layer of polythene for ease of handling and to protect from water. In the event of a fire the RTF and RRF intumescent material which makes these roof cavity fire stop products will expand to close the gap between the top of the wall/spandrel panel and the roof/ridge tiles, whilst also separating the roof batten and ridge tile timbers, providing effective fire resistance for 60 minutes, depending upon the non-combustibility of the roof covering (tiles) and the construction of the compartment/party wall.
