Abstract
A conservatory roof (10) has glazing bars (14) mounted on an eaves beam (16) with a thermal break (40) between the two. The thermal break (40) can be in the form of an insulating strip of plastic which snap-fits onto the head of the eaves beam (16). The eaves beam (16) may be generally L-shaped, having a double walled upstand (20) and an enlarged head. The head may have two areas (32, 34) on which glazing bars (14) can be supported depending on the pitch of the roof and the insulating strip (40) can cover both areas of the head. The insulating strip (40) may have ribs (50) on the underside to space the strip (40) from the eaves beam (16). The insulating strip (40) can have at least one location for the attachment of internal cladding (66) and the eaves beam (16) may support guttering (60).
Description
TITLE : Roof construction
DESCRIPTION
This invention concerns roof construction and, in particular concerns glazed roof construction, such as for forming a conservatory.
Conservatory roofs are generally formed from glazing panels supported at their edges by glazing bars fixed between a ridge beam and an eaves beam. The glazing bars and eaves beams are usually made of aluminium and their contact is a source of cold spot formation that can lead to condensation formation within the conservatory, which is undesirable.
An object of this invention is to improve thermal properties for a conservatory roof.
According to this invention is proposed a thermal break be interposed between glazing bars and an eaves beam in forming a conservatory roof.
The preferred eaves beam for use in the invention is generally L-shaped having an upstand and a base plate. The upstand may be double walled. The upstand preferably has an enlarged head. The eaves beam preferably has at least one location for attachment of internal cladding and at least one location for attachment of guttering or of brackets for supporting guttering. The base plate in use sits on a supporting structure, such as a wall or window frames.
The thermal break is preferably in the form of an insulator strip of plastics material that lies on the eaves beam. The insulator strip is preferably a snap fit onto a head of the eaves beam For example, the eaves beam head may have lips on opposite sides over which resiliently deformable sides of the strip can snap fit.
The head of the eaves beam preferably has two alternative areas on which glazing bars can rest depending on the roof pitch. The insulator strip matches those areas in profile but it is preferred that those areas of the insulator strip have ribs or the like on its underside to space the strip from the eaves beam to improve insulation properties.
The head of the eaves beam preferably has a depression therein to receive and guide fixing screws for securing the glazing bars to the eaves beam. That depression preferably has a roughened, say serrated surface, to provide grip for the screw point as it is being screwed through a glazing bar into the eaves beam.
The insulator strip preferably also has on its intended outer end, i. e. relative to the conservatory, a deformable web for bridging any gap between the eaves beam and the overlying glazing bars or panels.
The insulator strip also preferably provides a location for attachment of the internal cladding to cover the eaves beam. The insulator strip may have a downwardly open slot to receive a top edge of a cladding piece. The eaves beam may have a rib, such as of the so-called fir-tree type that fits into a channel or slot formed on the intended hidden face of the cladding.
The base plate of the eaves beam may also have a sealing strip applied thereto, the sealing strip having a deformable web that bridges between the base plate and the underside of guttering attached to the eaves beam. The sealing strip may also have a downstand to hide the junction between the base plate of the eaves beam and the supporting structure.
This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a section through a low pitch conservatory roof at its eaves; and
Figure 2 is a section through a higher pitch conservatory roof at its eaves.
Referring to Figure 1 of the accompanying drawings, a conservatory roof 10 comprises glazing panels 12 supported between glazing bars 14, the glazing bars being secured at their top ends to a ridge beam (not shown) and at bottom ends to an eaves beam 16. The glazing bars, ridge beam and eaves beam are all made from aluminium.
The glazing bars 14 are of inverted T-section having a cross bar and an upstand.
The glazing panels sit on the cross bar and are held down by top cappings 18 that are clip fits onto the glazing bars.
The eaves beam 16 is generally L-shaped having a double walled upstand 20 and a single walled base plate 22. The base plate 22 sits on and is secured to the underlying support structure, such as provided by window frames 24. The upstand has 20 an enlarged head 26 with a generally arcuate top surface but with a depression 28 therein.
The base of the depression has a serrated or roughened surface. Either side of the depression, the head of the eaves beam has two alternative inner and outer areas 32 and 34 respectively on which glazing bars can rest depending on the pitch of the roof. In this embodiment the roof illustrated has a low pitch and so the eaves beam 16 rests on the inner area 32.
Interposed between the glazing bars and the eaves beam and lying on the eaves beam is a thermal insulator strip 40 of plastics material. The insulator strip 40 snap fits onto the head 26 of the eaves beam. On opposite sides of the head of the eaves beam are ribs 42,44 over which lips 46,48 of the insulator can snap.
The insulator strip is formed as an extrusion and has a profile generally following the contours of the head of the eaves beam. The insulator strip is provided with ribs 50 on its underside to space inner and outer parts 52,54 thereof from the inner and outer areas 32,34 of the eaves beam head, whilst a central part 56 of the insulator strip sits in the depression in the head of the eaves beam. The inner and outer parts 52,54 of the insulator strip are provided on their top surfaces with double-sided adhesive tape 57 in order to hold the glazing bars 14 in place whilst they are being secured with screws 58 to the eaves beam.
Extending forwardly of the insulator strip i. e. towards gutter 60 on the outside of the conservatory is a thin resiliently flexible web 62. The web 62 contacts the underside of the glazing bar 14 or any bottom capping thereon or the underside of the glazing panels 12 to provide a wind break.
On its inner end i. e. the end towards the inside of the conservatory, the insulator strip has a lip 64 extending outwardly and then downwardly to form a slot which serves as a top location for internal plastics cladding 66 for the eaves beam 16. The eaves beam has lower down a fir-tree connector 68 along its length onto which a slot 70 of the cladding is a push-fit.
The eaves beam 16 supports brackets 72 for the gutter 60 and the leading edge of the base plate 22 of the eaves beam has a push-fit trim 76 thereon, which has a flexible resilient web 78 upstanding to seal between the underside of the gutter and the eaves beam. Furthermore, the trim has a downstand 80 to cover profile features.
The insulator strip provides a thermal break between the glazing bars and the
eaves beam, which otherwise, both being of aluminium, would provide a route for heat
loss leading to condensation formation within the conservatory on the eaves beam.
Turning to Figure 2 of the drawings, a similar arrangement is shown but with a
pitched roof of greater slope. The components are the same as in Figure 1 and have been
given the same reference numerals. In this arrangement the glazing bars rest on the
outer area 34 of the insulator rather than the inner area 32 and the web 62 of the insulator
strip is deformed more because of the slope of the roof.
