- The invention also provides a roof or wall structure incorporating a panel of the invention.
- The invention will be more clearly understood from the following description thereof given by way of example only, with reference to the accompanying drawings, in which:—
-
FIG. 1 is a perspective view of a translucent panel according to the invention, in use; -
FIG. 2 is a perspective view from the underside of the panel; -
FIG. 3 is a side view of the panel; -
FIG. 4 is an end view of the panel; -
FIGS. 5( a) to 5(g) are side views illustrating the collapsing of inner liner skin and multiwall support at an overlap portion; -
FIG. 6 is an enlarged end view of an overlap portion prior to collapsing of the inner liner skin and multiwall support; -
FIG. 6( a) is an enlarged end view of the overlap portion after first stage collapsing of the inner liner skin and multiwall support; -
FIG. 6( b) is an enlarged end view of the overlap portion prior to second stage collapsing of the inner liner skin and multiwall support; -
FIG. 6( c) is an enlarged end view of the overlap portion after second stage collapsing of the inner liner skin and multiwall support; -
FIG. 6( d) is an enlarged view of part of the overlap portion, after collapsing; -
FIG. 6( e) is a cross-sectional view of the overlap portion showing the end collapse/sealing; -
FIG. 7 is a perspective view of a fixing used with the panel; and -
FIG. 8 is an end view of the panel, and a spacer fixed to a purlin using the fixing ofFIG. 7 . - Referring to the drawings there is illustrated a translucent panel or
rooflight 1 comprising a single body of translucent polycarbonate material, the single body comprising a profiledouter weather skin 2, aninner liner skin 3 and, amultiwall support 4 between theinner liner 3 and theweather skin 2. Theinner liner skin 3,outer weather skin 2, and the multiwall support are all of translucent polycarbonate material. Therooflight 1 may be of Lexan Thermoclear multiwall polycarbonate sheet from GE Structural Products. This material is highly resistant to sheet covering discoloration, loss of light and loss of strength due to weathering. - The
panel 1 has anintegral overlap portion 10 which is illustrated in this case at one end of the panel. This is used for overlapping with other panels such as composite insulating roof or wall panels of similar profile. Theoverlap portion 10 has a substantially reduced thickness with respect to the overall thickness of the panel and in this case the thickness is reduced to close to thickness of theouter weather skin 2. - Referring in particular to
FIGS. 5 and 6 this is achieved by collapsing and/or forcing theinner liner skin 3 and themultiwall support 4 in the region of the overlap towards theouter weather skin 2. In a first step (FIG. 5( a)) theinner liner skin 3 is notched at 11 with a cutting tool 12. A first heatedpressing tool 15 of complementary profile to that of the outer skin is then pressed against theinner liner skin 3 and multiwall support 4 (FIGS. 5( b), 5(c)) which are melded to the inner surface of the outer skin 2 (FIGS. 5( d), 6(a)). The meldedmaterial 19 is shown in exaggerated form and thickness inFIG. 6( a). In the invention, part of the overlap portion, in this case theend edge 60 is sealed to ensure that there is no possibility of water ingress at the end edge. The meldedend edge 60 is particularly shown inFIG. 6( e). This is achieved in this case by a second stage pressing/heat sealing using a secondpressing tool 21 which is pressed against thecollapsed end edge 60 to further meld/seal the polycarbonate material. The melded/sealedend edge 60 ensures that there is no possibility of moisture, dirt or other ingress at this edge. Using a pressing tool is a very efficient method for manufacture on a large factory scale. - The
panel 1 further comprises aborder 25 extending between the main panel portion and theoverlap 10. Theborder 25 has a depth comprising the overall depth of themultiwall support 4 and theinner liner skin 3 and extends substantially at right angles to theouter weather skin 2 andinner liner skin 3. - Formation of the
notch 11 prior to pressing provides for theborder 25 on pressing. In the preferred embodiment shown thenotch 11 extends across the width of the panel, however, it will be appreciated that the depth and/or extent of thenotch 11 may be varied as required. - In use, the
border 25 andoverlap portion 10 together define a connection means for connection of thepanel 1 with adjacent panels having a similar profile. The adjacent panels may be rooflight panels or insulated building panels having the same profile as the outer weather skin. The adjacent panels may be of a similar or greater thickness than thepanel 1. Thepanel 1 is configured so that in use theoverlap 10 overlaps an adjacent panel of a similar profile and theborder 25 lies side by side in close abutment with the side edge of the adjacent panel. A sealing member for example, a tape covering may be applied to theborder 25. Theoverlap 10 andborder 25 provide for an improved connection between thepanels 1 and adjacent roof panels and also for improved seal and insulation of the roofing system. - As noted above, the pressing tool has the profile of the
outer skin 2 so that theinner liner skin 3 andmultiwall support 4 are compressed against the outer skin, but the overall profile of the outer skin is maintained. Theoverlap 10 extends laterally across the width of thepanel 1. In the embodiment shown theouter skin 2 is profiled and the overlap is formed in such a way as to maintain the profile of the outer weather skin at theoverlap 10. This provides a good aesthetic finish to the roof and ensures that an improved seal and connection is achieved between thepanel 1 and adjacent panels. - In addition to the
overlap portion 10 which in the embodiment shown extends laterally, thepanel 1 further comprises a side lap 26 (FIGS. 1 and 2 ) which extends longitudinally along one side of thepanel 1. Theside lap 26 in this case comprises only theouter skin 2 and provides means for connection with adjacent profiled building panels or adjacent likepanels 1. If necessary theside lap 26 may be formed in process similar to that for forming theoverlap 10. - The
panel 1 also comprises at least one and in this case a number ofspacers 20 for extending between the outer surface of theinner liner 3 and a building frame element such as aroof purlin 40. Thespacer 20 may for example be of hollow PVC section. For ease of use on-site, preferably thespacer 20 is attached, for example by bonding such as adhesive bonding, to thepanel 1 at the production stage. Thespacers 20 are used to bridge the gap in thickness between theshallow rooflight 1 and an adjacent thicker composite insulated panel. The rooflight is shallow because of the high thermal insulation efficiency of the translucent panel. - It is noted that the
border 25 provides a clearly defined attachment region to enable attachment of spacers directly adjacent to theoverlap portion 10 of thepanel 1. In this way aspacer 20 can be located side by side with the side edge of an adjacent panel so that theborder 25 and thespacer 20 together overlap portions of the side edge of an adjacent insulated panel. The insulated panel may have a thickness greater than the thickness of thepanel 1 at the border. This provides for a good seal and good insulation at the connection. - Referring in particular to
FIGS. 7 and 8 there is illustrated a fixing 30 which is used for fixing thepanel 1 to a building frame element such as theroof purlin 40. The fixing has ashaft 31 with adrill point 32 for drilling through the panel, thespacer 20, and into thepurlin 40. The fixing also has sharpenedside flanges 33 which provide reaming elements for reaming ahole 35 in thepanel 1 that is larger in diameter than the diameter of theshaft 31 of the fixing. Suchlarge holes 35 in the panel facilitate any thermal expansion that may occur in the panel without adversely affecting the integrity of the panel at the fixings. - The rooflights of the invention have excellent U-value ratings, do not suffer from the effects of thermal expansion and provide excellent light transmission properties.
- In the embodiment described the panel is comprised of a translucent polycarbonate material. It will however, be appreciated that the panel may be comprised of any suitable thermosetting material.
- The process of forming the
rooflights 1 of the invention as described has advantages including being efficiency and cost effectiveness. It will however be appreciated that the rooflights of the invention may be formed by other suitable means. - The rooflights of the invention have advantages over prior art rooflights including the following. The provision of an overlap portion enables the rooflight panel to be securely connected to adjacent profiled structural roof panels. The profiled form of the rooflight overlap provides a good aesthetic finish and a positive connection between the panels and for an improved weatherproof sealed finish.
- The rooflight of the invention comprises connection means to enable secure connection with adjacent similar rooflight panels and/or insulated building panels which may have a thickness greater than the thickness of the rooflight. The rooflight is configured to provide for a side by side connection of the rooflight with the adjacent panel by virtue of the overlap and border features. This arrangement provides improved sealing and insulation between the rooflights and adjacent roof panels.
- The spacer and fixing features of the rooflights of the invention provide further advantages. The spacer provides for an improved structural connection between the panels and the roof system which provides a roof having improved insulation properties. The panel of the invention is formed to facilitate any thermal expansion that may occur in the panel.
- The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
