• the panel element 2 comprises a translucent panel or rooflight of the type described in our GA-A-2413808, the entire contents of which are incorporated herein by reference.
• the panel 2 comprises a single body of translucent polycarbonate material, the single body comprising a profiled outer weather skin, an inner liner skin, and a multiwall support between the inner liner skin and the outer weather skin.
• the inner liner skin, the outer weather skin, and the multiwall support are all of translucent polycarbonate material.
• the rooflight 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 element 2 has an integral overlap portion at one end of the panel element 2. This is used for overlapping with other panels such as composite insulating roof panels or wall panels of similar profile.
• the overlap portion has a substantially reduced thickness with respect to the overall thickness of the panel element 2 and in this case the thickness is reduced to close to the thickness of the outer weather skin. This is achieved by collapsing and/or forcing the inner liner skin and the multiwall support in the region of the overlap towards the outer weather skin.
• the inner liner skin is notched with a cutting tool.
• a heated pressing tool of complementary profile to that of the outer weather skin is then pressed against the inner liner skin and the multiwall support which are melded to the inner surface of the outer weather skin. We have found that this is a very efficient method for manufacture on a large factory scale.
• the panel element 2 further comprises a border extending between the main panel portion and the overlap portion.
• the border has a depth comprising the overall depth of the multiwall support and the inner liner skin, and extends substantially at right angles to the outer weather skin and the inner liner skin. Formation of the notch prior to pressing provides for the border on pressing. In a preferred embodiment, the notch extends across the width of the panel element 2, however, it will be appreciated that the depth and/or extent of the notch may be varied as required.
• the border and the overlap portion together define a connection means for connection of the panel element 2 with adjacent panels having a similar profile.
• the adjacent panels may be rooflight panels 2 or insulated building panels 22 having the same profile as the outer weather skin.
• the adjacent panels may be of a similar or greater thickness than the panel element 2.
• the panel element 2 is configured so that in use the overlap portion overlaps an adjacent panel of a similar profile and the border 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 the border.
• the overlap portion and the border provide for an improved connection between the panel element 2 and adjacent roof panels and also for improved sealing and insulation of the roofing system.
• the pressing tool has the profile of the outer weather skin so that the inner liner skin and the multiwall support are compressed against the outer weather skin, but the overall profile of the outer weather skin is maintained.
• the overlap portion extends laterally across the width of the panel element 2.
• the outer weather skin is profiled and the overlap portion is formed in such a way as to maintain the profile of the outer weather skin at the overlap portion. This provides a good aesthetic finish to the roof and ensures that an improved seal and connection is achieved between the panel element 2 and adjacent panels.
• the panel element 2 further comprises a side lap which extends longitudinally along one side of the panel element 2.
• the side lap in this case comprises only the outer weather skin and provides a means for connection with adjacent profiled building panels or adjacent like panel elements 2. If necessary the side lap may be formed in a process similar to that for forming the overlap portion.
• the spacer 4 extends between the outer surface of the inner liner skin of the translucent panel 2 and the roof purlin 3.
• the spacer 4 is magnetic.
• a ferro-magnetic material may be incorporated into the material of the spacer or the spacer may be rendered magnetic by, for example, a magnetic strip.
• the spacer 4 is provided in this case in the form of a beam, and may for example be of hollow PVC double box- section.
• the spacer 4 is used to bridge the gap in thickness between the relatively shallow rooflight 2 and the purlin 3.
• the location of the purlins 3 is set to accommodate the opaque insulated panels which are thicker than the translucent panels.
• the rooflight 2 is thinner than the opaque panels 22 because of the high thermal insulation efficiency of the translucent panel element 2.
• a fixing pin 5 is used for attaching the translucent panel element 2 to the spacer 4, and attaching the spacer 4 to the roof purlin 3.
• the fixing pin 5 has a shaft 6 with a drill point 7 for drilling through the panel element 2, the spacer 4, and into the purlin 3.
• the spacer 4 and the panel element 2 are formed separately, and are not attached to each other during production.
• the spacer 4 and the panel element 2 are provided to the intended site of use detached from one another.
• the spacer 4 is magnetically coupled to the purlin 3 on-site, due to the spacer 4 being magnetic and the purlin 3 being of a metallic material.
• the translucent panel element 2 is then placed resting on top of the spacer 4 with the longitudinal axis of the panel element 2 substantially perpendicular to the longitudinal axis of the spacer 4.
• the fixing pin 5 is then extended through the panel element 2 into the spacer 4, and through the spacer 4 into the purlin 3 by means of drilling. In this manner the panel element 2 is attached to the spacer 4 on-site, and the spacer 4 is attached to the purlin 3 on-site. Overall the panel element 2 is effectively attached to the purlin 3 on- site via the spacer 4 by means of the fixing pin 5. Because the spacer 4 is not attached to the panel element 2 during production, this enables the user to adjust the position of the spacer 4 relative to the panel element 2 on-site, and to adjust the position of the spacer 4 relative to the purlin 3 on-site to ensure that all of the components: the panel element 2, the spacer 4 and the purlin 3 are in the desired position.
• the magnetic coupling of the spacer 4 to the purlin 3 provides a convenient means of temporarily retaining the spacer 4 in place while the steps of positioning the panel element 2 and drilling of the fixing pin 5 take place.
