Description
- The present invention relates to a firebreak roof divide system for preventing the spread of fire between adjacent structural members and more particularly to a barrier for use in a gap between a roof and a party wall of a building.
- A variety of solutions have been proposed to overcome these problems.
GB Patent No. 2 082 647 - The problem to be solved by the present invention is to reduce the overall size of such a barrier and facilitate its efficient storage and transportation.
- The present invention provides a barrier for use in a gap between a roof and a party wall of a building to prevent the spread of fire, the barrier comprising a channel section for mounting on top of the party wall dividing two areas of the building and for receiving a barrier element which extends upwardly to abut the roof to seal the gap between the wall and the roof, a wing mountable on each side of the channel section, wherein the wings are formed as v-sections and are adapted to receive roofing felt from both sides of the building. Supplying the channel section and wings as separate parts reduces the overall size of the barrier and alleviates difficulties associated with their transport and storage.
- Ideally, the channel section, comprising a base and two side walls, rests on its base on a gasket layer of mineral wool fixed to the top of the party wall, preventing smoke from spreading under the barrier into the adjoining building through small gaps between the top of the party wall and the base of the channel section.
- The wings of the barrier are formed as v-sections. This allows stacking of the sections during both storage and transport thus reducing the floor space required for them.
- Ideally, one web of the wing includes an attachment means on its free end for mounting the wing onto a side wall of the channel section.
- Ideally, both webs of the wing include an attachment means on their free end for mounting the wing onto either side wall of the channel section. An attachment means on both webs of the wing allows one part to be mounted on both side walls of the channel section. This reduces the number of parts to be manufactured thus reducing the overall cost of the barrier.
- In one embodiment, the barrier element is provided by a block of mineral wool in the form of a cockscomb vertical brush.
- Preferably, the channel section is provided by a number of separate overlapping sections or parts. Division of the channel section into parts reduces the difficulties encountered during installation and removes problems associated with handling, transporting and storing unnecessarily long sections of construction material.
- In a particularly preferred embodiment, the channel section comprises an eaves section, a main section and a ridge section.
- Ideally, the eaves channel section has a crinkle portion incorporated to allow the installer to tilt it to the required angle to a fascia board and guttering to suit specific requirements.
- Preferably, the ridge channel is formed with a crinkle portion to allow a user to bend the section over a ridge at the top of a roof and down along the pitch on the opposite side. This allows a continuous section of channel to extend around the ridge of the roof.
- The wings can be manufactured from polyvinyl chloride, aluminium or steel.
- Preferably, a chimney unit is provided at the junction between an upper portion of the party wall and a chimney for receiving the channel section and wings which are mounted on this portion of the party wall.
- Ideally, the chimney unit comprises a tray and a wall extending around a substantial portion of the perimeter of the tray defining a gap, the tray having an outlet located adjacent the perimeter wall opposite the gap and a flexible pipe attached to the outlet underneath the tray.
- Preferably, the chimney unit is mounted on the gasket layer with the outlet adjacent the chimney wall and the gap facing towards the ridge of the roof for receiving the channel section and wings which are mounted on this portion of the party wall. In this orientation, the tray receives water from the wings that has leaked through the tiles unto the felt and passes it towards the outlet. It is passed back onto the felt at the side of the chimney via the flexible pipe.
- Advantageously, the channel section is of a dovetail cross-section with a wider base and a narrower opening.
- The invention will now be described with reference to the accompanying drawings, which show, by way of example only, a number of embodiments of a barrier according to the invention in which:
