Abstract

A method of renovating a glazed roof comprises retrofitting an elongate aluminium component over an existing capping strip 24. The existing capping strip 24 is removed from a rafter 2 supporting the glazing panels 40. Longitudinal grooves are formed in an aluminium sheet which is then bent along the grooves to form a cover 34 engaging the external profile of the capping trim 10 and locating at least a portion of the capping strip within the metal cover 34 and then re-attaching the capping strip with the rafter. A portion of the aluminium cover may be located between the capping strip and the glazing panels.

Description

METHOD OF RENOVATING A GLAZED ROOF
Field of the Invention
This invention relates to a method of renovating a glazed roof of the type used in conservatories.
Background to the Invention
Glazing systems for conservatories and like glazed roofs may comprise rafters or like roof elements extruded from aluminium or plastics and having flat surfaces for receiving the edges of glazing panels, with an upstand which can be engaged by a capping strip enclosing the upstand and having, in section, downwardly-extending legs which contact the upper or outward face of the glaz-ing panel to hold it in place against the rafter. The upstand may be configured with a slot therealong into which formations within the capping strip may be en-gaged to hold it in place, or the capping strip may include formations which clip on to the outside of the upstand.
is In order to provide the clipping function, the capping strip is typically formed from a resilient plastics material, typically by extrusion. Prolonged ex-posure to sunlight and the weather can degrade the plastics material, adversely affecting the appearance, and in some cases leading to brittleness of the plas-tics material, in turn leading to cracking or splitting.
While failure of the capping strip is less likely if it is left undisturbed, it may be desired to replace the glazing panel with a different type of panel, for example a thermally insulating panel of the type disclosed in our earlier patent application published under GB2486296A. Removal of the capping strip to permit replacement of the panel may result in damage to the strip, but it may also be desirable to use a capping strip that will match the colour and finish of the replacement panel.
While it is possible simply to replace the capping strip with a new one, it may be difficult to source a matching strip that will engage the upstand of the rafter correctly, or is of the desired colour, for example. In addition, the capping strips can be costly.
Summary of the Invention
Accordingly, the present invention provides a method of renovating a glazed roof of the type having rafters or like supporting elements supporting the edges of glazing panels and capping strips engageable with the rafters to hold the glazing panels to the rafters, the method comprising removing the capping strip from the rafter, forming longitudinal grooves in an elongate aluminium sheet material, bending the sheet material along the grooves to form a cover engaging the external profile of the capping strip, locating the capping strip, or at least portions thereof, within the cover, and re-engaging the capping strip with the rafter.
Preferably, the cover is shaped such as to engage the capping strip at at least the highest point thereof relative to the rafter when positioned thereon, and suitably also provides portions which extend between the capping strip and the glazing panel or panels, when the capping strip is re-engaged with the rafter.
The grooves may be formed by routing and are preferably of a part-circular profile.
The method of the invention provides a simple and effective way of refit-ting or replacing the glazing panels without the need to replace the capping strips.
Brief Description of the Drawings
In the drawings, which illustrate an exemplary embodiment of the inven-tion: Figure 1 is a cross-sectional view of a portion of a conventional roof, showing the rafter and capping in place thereon holding glazing panels; Figure 2 illustrates an aluminium sheet formed with grooves in accord-ance with the invention; Figure 3 shows the aluminium sheet after bending into shape; and Figure 4 shows the same view as in Figure 1, after fitting of the bent al-uminium sheet.
Detailed Description of the Illustrated Embodiment
Referring to Figure 1, a conservatory roof has a rafter 1 consisting of an extruded member having a main portion 2 presenting on the upper face thereof a pair of flat glazing surfaces 4 and 6, separated by an upstand 8 which is hol-low and has an outwardly-directed slot 10 therein. The glazing surfaces 4 and 6 are provided with resilient gaskets 12 and 14 on which glazing panels 16 and 18 rest. The glazing panels 16 and 18 may be glass, but are more conveniently multi-layer plastics extrusions affording better thermal insulation properties, while being lighter in weight and less likely to shatter than glass. Such extruded sheets are well-known in the conservatory field. The gaskets 12 and 14 serve to seal against water ingress, as well as protecting the edge of the glazing pan-el, particularly where glass is used. Resilient strips 20 and 22 are provided on top of the glazing panels 16 and 18, and a capping strip 24 is used to hold the glazing panels 16 and 18 in place, while at the same time enclosing the rafter is upstand against the weather and preventing water ingress. The capping strip 24 is conveniently a plastics extrusion, having a generally channel-shaped form with a pair of resilient tabs 26 extending within the channel to engage in the slot 10. The tabs 26 diverge and have ribs 28 along their tree ends to help retain the strip in place. The ribs 28 are shaped so as to enable them to be force to-gether through the slot 10 when a downward force is exerted on the capping strip 24, the tabs springing apart when the ribs have passed through the slot 10.
The strip therefore requires an upward force to detach it from the rafter.
Figure 2 shows a portion of aluminium sheet 30 formed with parallel grooves 32 along one face thereof, for example by means of a router. The grooves 32 permit the sheet to be bent to form a shaped cover 34 which ap-proximately conforms with the shape of the capping strip, as shown in Figure 3.
It is not important that the cover 34 conforms exactly with the exterior of the capping strip; the upper part of the shape needs to contact the uppermost part of the capping strip 24 so that pressing downwardly on the aluminium cover causes engagement of the tabs 26 in the slot 10 in the upstand 8 of the rafter 1.
The cover 34 has inwardly-directed portions 36 which fit under the sides of the capping strip 24, completely enclosing it.
Figure 4 shows the use of the cover 34 in conjunction with the replace-ment of the glazing panels 16 and 18 with opaque insulating panels 40 and 42 of the type disclosed and claimed in 3B2486296A. The capping strip 24 is slid into the cover 34 from the end thereof. If the capping strip becomes damaged during its removal from the rafter 1, it can still be used in portions, as its function is merely to enable attachment of the cover to the rafter without the need for in-ternal tabs on the cover itself.
