Abstract

The system comprises a plurality of interlocking panels 1, each comprising a ribbed upper surface 16 for supporting roof tiles and whereby the interlocking portions 13, 17 (figure 2) of the panels form a water drainage channel 12. The system may comprise an eaves soffit board 8, draught seal, pre bonded vapour barrier, and an eaves fascia board 9 comprising pre bonded drip flashings 10, 11. Lower and upper connecting edges of adjacent panels may have a stepped and sloping joint 19 between them. The underside of the panels may be flat, or may have grooves for receiving roof joists, and the panels may span the length of the roof. There may be three types of panel, an eaves panel, an intermediate panel and a ridge panel.

Description

Combined Roof Insulation and Tile Support Panel System This invention relates to a combined system of under tile roof insulation and roof tile support which also provides a secondary waterproof layer, more normally provided in a traditional roof by the underlay. The invention is achieved by combining the individual function of traditional elements into groups of novel components which incorporate novel interlocking features.

Background

The traditional form of roof for many buildings is the pitched, tiled and for slated roof.

Typically, such roofs consist of: slates or tiles; laid onto horizontal battens; the battens are fixed to the roof structure; between the battens and the slates or tiles is a secondary waterproof underlay; thermal insulation is provided, either at ceiling level, or within the roof structule, or above the roof structure; additionally and dependant on where the insulation zone is located, systems that allow for ventilation of the space between the insulation and the roof covering are also provided.

In addition to this, in certain circumstances a finish is provided to the sloping soffit (for example, in rooms in the loof space); and the finish to this soffit may have a vapour barrier located between its upper surface and the underside of the roof structure.

In addition to this, there is also labour involved in the formation of the eaves fascia and eaves soffit boards.

So, beneath the roof covering, there are usually six elements of battens, secondary waterproof membrane, insulation, vapour barrier finishing soffit board, and ventilation products.

Statement of Invention

This invention combines the functions of the various elements beneath the roof covering, as described undel the heading, Background' above; i.e.', the six elements of battens, secondary waterproof membrane, insulation, vapour barrier finishing soffit board, and ventilation products and eaves fascia and eaves soffit.

The combination takes the form of an interlocking panel system of eaves panel 1, intermediate panel 3 and ridge panel 5 or mono pitch top panel 4. A novel feature of this invention is the way that each component connects with the other components of the system. Current under tile roof systems do not interlock in this novel way, nor do they incorporate the six elements listed in the foregoing paragraph.

The panels have a ribbed upper surface which forms the support batten' for the tiles. The ribs are located at centres that allow for the fixing of slates and plain tiles on every rib and for the fixing of interlocking tiles on alternate ribs. Thus providing a system that accommodates both slates and plain tiles, and interlocking tiles, without modification. The design can be adapted so that the rib centies are at a greater distance apart so that they accept only interlocking tiles.

The panels can be of a length that spans from eaves to ridge in one length, effectively combining the function of eaves panel 1, intermediate panel 3 and ridge panel 5 or mono pitch top panel 4.

The ridge / mono pitch top can be formed from with a special panel as described above, or by cutting an intermediate panel on site and providing either a top flashing or a sealed joint, or a combination of both.

The panels incorporate overlapping and interlocking joints so that any water that passes through the tiles or slates is led away to the eaves gutters thereby performing the function of the secondary waterproof underlay employed in traditional forms of roof construction.

These overlapping and interlocking joints can optionally include a draught seal.

The underside of the panels can either be flat, or incorporate grooves, into which the roof joists can be located.

The underside of the panels can also incorporate a soffit finish and cover strips for the roof joists which can be either flush, recessed, or project beneath the soffit.

The thickness of the panels can be increased or decreased to vary both the thermal insulation value and the required structural support centres.

The material from which the panels are made can also be varied to vary both the thermal insulation value and the required structural support centres.

Advantages The advantages of this invention are: Simplification of the design of the roof structure and covering system.

Time savings because the speed of erection is much faster than the traditional methods.

Savings in labour and specialist skills compared with traditional methods Cost savings.

Thermal efficiency.

Potential for a reduction in the number of structural supports (e.g., increased rafter centres).

Description of the Invention

There now follows, by way of example of the invention, a detailed description which should be read with reference to the accompanying drawings which are: Fig's 1 and 2 Show the arrangement of eaves panel 1.

Eaves panel 1 comprises: a moulded insulation board; a pre bonded finish 7, including but not limited to plasterboard and having the facility to incorporate a vapour barrier and which may or may not be included in the system; a pre bonded eaves soffit board 8 which may or may not be included in the system; a pre bonded fascia board 8 which may or may not be included in the system; pre bonded drip flashings 10 and 11 which may or may not be included in the system; 12 is the drainage channel at the connecting junction of adjacent panels; 13 is the edge of the drainage channel; 14 is the arrangement at the junction of drainage channel edges, it is arranged with a step so that water is directed away from the gap between adjoining panels; is the edge of the drainage channel at the lower end of the panel; 16 are the recesses upon which the nibs on the roof tiles will lodge. They are located so that plain tiles, which have a small gauge, are laid using every recess and interlocking tiles, which have a larger gauge can be laid using alternate recesses. As an alternative, the panels can be manufactured with a gauge that is specific to the type of roof tile to be used.

17 is the recess in the underside of the panel that accommodates the edge of the drainage channel 13; 18 is the recess in the underside of the panel that accommodates the edge of the drainage channel at the lower end of the panel 14; 19 is the lower part of the stepped connection between a lower and higher panel.

The combination of features and items numbered 12, 13, 14, 15, 17, and 18 form the interlocking arrangement at the side junction of adjoining panels.

A novel feature of this junction is the way in which the combined features both interlock and form a water drainage channel.

Another novel feature is that the eaves panel is an interlocking component that combines the six elements found in a traditional roof (i.e., battens, secondary waterproof membrane, insulation, vapour barrier finishing soffit board, and ventilation products) into one interlockable component. Whilst the prior art includes all of these features in the roof as a whole, it does not include them in one interlockable component, instead, each element has to be installed individually.

Figs 3 and 4 Show perspective views of the roof constructed using this invention, in particular, how the eaves panel 1, is laid onto the roof structure 20. The centres of the roof structure 18 can be set to suit the load bearing capability of the panels 1, 2, 3, 4 and 5.

A novel feature is that this interlockable component comprises the whole of the eaves assembly Figs 5 and 6 Show perspective views of the roof constructed using this invention, in particular, how the adjoining eaves panel components 1, interconnect, particularly how the upstand 13 forming the edge of the drainage channel 12 enables the panels to interlock and stops water from running inside the building. Also sown is how the arrangement at the junction of drainage channel edges 14 is arranged so that water is directed away from the gap between adjoining panels.

Figs 7 and 8 Shows the arrangement of intermediate panel 3.

Intermediate panel 3 comprises: a moulded insulation board; a pre bonded finish 7, including but not limited to plasterboard and having the facility to incorporate a vapour barrier and which may or may not be included in the system; 12 is the drainage channel at the connecting junction of adjacent panels; 13 is the edge of the drainage channel; 14 is the arrangement at the junction of drainage channel edges, it is arranged so that water is directed away from the gap between adjoining panels; 16 are the ribs upon which the nibs on the roof tiles will lodge. They are located so that plain tiles, which have a small gauge, are laid using every recess and interlocking tiles, which have a larger gauge can be laid using alternate recesses. As an alternative, the panels can be manufactured with a gauge that is specific to the type of roof tile to be used.

17 is the recess in the underside of the panel that accommodates the edge of the drainage channel 13; is an anti capillary groove which, alternatively can accommodate a sealing strip.

21 and 22 are the bottom and top edges of the panels which have overlapping edges which may or may not be tapered.

It is the combination of features and items numbered 12, 13, 14, 15, 17, and 18 which form the interlocking arrangement at the side junction of adjoining panels. A novel feature of this junction is the way in which the combined features both interlock and form a water drainage channel.

Another novel feature is that the intermediate panel is an interlocking component that combines the six elements found in a traditional roof (i.e., battens, secondary waterproof membrane, insulation, vapour barrier finishing soffit board, and ventilation products) into one interlockable component. Whilst the prior art includes all of these features in the roof as a whole, it does not include them in one interlockable component, instead, each element has to be installed individually.

Figs 9and 10 Show perspective views of the roof constructed using this invention, in particular, how the adjoining eaves panels 1 and intermediate panel 3, interconnect, particularly how the upstand 13 forming the edge of the drainage channel 12 enables the panels to interlock and stop water from running inside the building. Also shown is how the arrangement at the junction of drainage channel edges 14 is arranged so that water is directed away from the gap between adjoining panels.

Figs 13 and 14 Show perspective views of the uppermost panels. Panel 4 is suitable for mono pitched roofs, or could be joined along the vertical edge to form a ridge panel like panel 5 that shown in Fig 20.

Panel 5 shown in Fig 20 is a ridge panel.

The features of these panels include those as previously described for panels 1 and 3.
