Abstract

An insulating panel 1 comprises a profiled translucent first sheet 2, a second sheet 4 with an insulating body, in this case an insulating foam 5 therebetween. The foam may be a polyisocyanurate foam or a phenolic foam. The sheet 2 is of a polycarbonate material which is relatively strong and durable. A solar collector 10 in the form of a flexible photovoltaic material is provided between upper sheet 2 and the insulation body. The solar collector may extend into the upper sheet profiles 3 or may be laid in strips 20 along and/or across the sheet 2. The solar collector is protected by the top sheet.

Siateincutx of Invention According to die invention dvr·: iv provided s composite irmel comprising an upper sheet. a lower sheet an·.! *«·: m ·'hod) between the upper sheet and die lower sheet wherein the U|)f\ t -.he;, i is ,0 n translucent iO ituria! and a .solar collector is provided between die ;;pix 1 dice! and the insuiaiion hodv in one embodiment the solar coiled»·..- comprises a flexible material.

Ihe solar collector may extend suhsmiutaMy t!ic width of the pane! or die sola;· collector may extend in strips. ! i\; snips may extend iransvcis-eiv across the panel. Alternatively or uddifon;d|\ die Strips extend longitudinal!) aiene the panel. 1:· **k 1 mivdiment the outer sheet comprises raised portions. In i.hf- case 11.-^ collector may extend into the raised portions. Alternatively the solar collcctoi does not extend into the raised portions.

In one embodiment the solar collector is mourned to the inner lace »>f tin- tipper dleei.

In one embodiment the solar collector i.\ adhesively bonded u- the inner l ice ol the upper .sheet. The adhesive is preferably translucent. The adhesive may be ο;·>\ ided over substantially ail of the inner lace of the upper ‘Teei ίο ·λhion me >t‘lr.r collector is applied. ii one ease there is a barrier beiuevn ihc solar collector and the insulating bod).

I he harrier may comprise a film.

In a pretevred embodiment the first sheet comprises a poiycvirbo'.y.iw material.

In one embodiment the outer sheet comprises a plurality of longitudinally raised projections. The raised projections muv comprise raised οοοιίν Ί he raised objections may be of generally trapezoidal form and extend longitudinal!) along Hie length of the panel.

In one east: !tie raised projections comprise u side underlap proicctmn anti a side u efiap projection for jointing adjacent iike panels. !n one case the second sheet comprises a steel material. ! he insulating body may comprise a foam such as a polyisoevanmaie foam, or a phenolic foam.

I he panel may7 be a rool panel, a wall panel, and/or a floor panel.
