Abstract

Extruded plastics roof tiles are of hollow cross-section to allow for roof ventilation. Openings 'B' may be formed in the underside to provide a ventilating path, and slots A throughout the length of a tile may allow for concealed fastening. The tiles may be transparent, and have double or treble skins. <IMAGE>

Description

EXTRUDED PLASTIC ROOF TILES This inventions relates to extruded hollow plastic roof ventilating tiles, which may be used in conjuction with standard solid tiles without disturbing roof profiles, which may also be used as the primary roofing tiles, and can be used in an elongated form to meet industrial roofs requirements.
Building regulations require the roof voids of new buildings to be ventilated. Standard solid roof tiles do not allow the required ventilation consequently special vents which interface with the solid tiles have been used to meet the ventilation requirement. These vents have broken the lines of the roofs and to overcome this patent applications GB 9313434.4 and GB 2262285A have disclosed alternative types of ventilating tile which do not break the lines of the roof.
All proposals for ventilating tiles previous to this application have contained some structural features common to standard solid tiles - such as nibs to engage with roof battens - and other mechanical features which constrain the type of manufacturing process which can be used and constrain the design options.
This invention removes these constraints and extends the options and applications beyond that of any previously known design.
According to the present invention hollow roof ventilating tiles which have constant cross section throughout their length to permit manufacture by a continuous plastic extrusion process are proposed. This invention allows the variation of tile length during manufacture to meet the requirements for longer tiles for industrial roofs. The invention also allows for the use of secret fixings Fig.l is a perspective underside view of a constant section tile suitable for manufacture by a continuous plastic extrusion process. The cut outs 'B' in the extruded tile allow it to engage the roof battens. When installed in a roof external air flows, or is drawn into ducts 'A' and deflected into the roof void when it meets the batten. Insect grids 'C' may be added in the air path.
Fig.2 Shows a section of an installed tile with ventilating tile 'E', battens 'F' and the air flow path 'D' solid tiles 'G'.
Fig.3 Shows a basic embodiment of the invention in a long, hollow, constant section, extruded plastic, interlocking tile suitable for use on industrial roofs.
Ventilation of interior of a roof is through cut-outs in the under surface The The upper end 'B' of the tile can be closed by an add-on plate to prevent the ingress of falling rain.
The tile of fig.3 can also be used as a non-ventilating tile and it can be produced in either opaque or transparent plastic. In its transparent plastic form it becomes a double glazed roof light and may be used without ventilation cut outs in its underside. It can also be extruded as a triple skin unit, as shown the end section shown in fig.4, to reduce heat loss through the roof. Fig.5 Shows the end section of a constant section tile with slots 'A' which run the full length of the tile. The section is suitable for secret fixing. Fig.6 shows a partial end section with a fixing bolt 'B' in position, the shank of this bolt sliding ' the slot 'A'.
