TBA Firefly Timber Penowrap

FRL 120/120/120

TBA Firefly Timber Penowrap® is used to maintain the full FRL of a fire compartment wall or fire barrier when it is penetrated by timbers. Strips of Plus 60 are wrapped around the timber and extended 300mm from the face of the barrier, and temporarily held in place using a hammer tacker and staples. The Green Collar Roll is then wrapped over the top of it and stapled to itself using an R31 Staple Gun, 12mm Stainless Steel Staples and double fold jointing method. The 100mm wide skirt of the Green Collar Roll is then shaped to the face of the compartment wall/fire barrier and glued into position using Intumastic. A bead of Intumastic is also required at the other end of the green sleeve to seal it to the Plus 60 and timber. This treatment is required to both sides of the compartment wall/fire barrier. If only 3 sides of the timber are accessible then the 3 sided, treatment may be used. However a 25mm x 25mm x 0.5mm galvanised angle is then required to mechanically fix both layers to the timber.
