  • an insulating panel 1 used in the invention comprising a first sheet 2, a second sheet 4 with an insulating body, in this case an insulating foam 5 therebetween.
  • the foam may, for example be a polyisocyanurate foam or a phenolic foam.
  • the panel 1 is a roof panel 1 comprising a profiled external sheet 2 which may be of painted galvanized steel.
  • the profile in this case comprises a plurality of projections, in this case raised crowns 3.
  • the crowns 3 in this case are of generally trapezoidal form and extend longitudinally along the length of the panel.
  • the panel also comprises an inner metal liner sheet 4.
  • the foam defines a plurality of longitudinally extending conduit means 7 through which a suitable heat exchange medium such as air is circulated.
  • the panel thus has an integral heat collecting means provided in some of the crowns 3 of the external sheet which are devoid of insulation 5.
  • the conduits 7 extend through the crowns 3 and air is circulated through the conduits 7.
  • the conduits 7 run through the roof and/or wall in the external envelope of the building and the air absorbs solar energy.
  • Conduits 7 may alternatively or additionally be provided in floor panels for heat circulation.
  • the warmed air may be pumped back into the building to provide heat to the building space. Once the heated air passes through the building and transfers its energy, it may flow back to the conduit in the roof and/or wall and/or floor panels and the process may be repeated in a closed loop.
  • Barriers in this case in the form of a membrane such as a tape or foil 10 are located below the crowns 3 to prevent foam entering the crowns 3 and in this case also to create additional foam-free voids below the crowns 3. This creates an enlarged void space through which air may be circulated to enhance the solar collecting efficiency of the panel.
  • the barriers 10 in this case have projecting side portions or legs 1 1 which may be attached, for example by adhesive to the inner face of the outer skin 3 of the panel.
  • the barriers 10 may be any suitable material such as foil or tape.
  • the barrier 10 is not planar and can be used to define conduits of any desired size and/or shape.
  • the barrier 10 has a pair of longitudinally extending transversely spaced-apart sides, 11 defining a plane therebetween and the barrier extends outside of said plane.
  • the barrier can therefore be extended into the main body of the foam.
  • the barrier can extend inwardly of the first sheet 2 and/or the second sheet 4 to provide a conduit of any desired size and shape.
  • the first and/or second sheets may be profiled and at least some of the profile recesses may form a conduit.
  • the conduit may be larger than the recess defined by the profile of the sheet.
  • the foam recess part is of a shape which is substantially a minor image of the profile recess part.
  • the cross sectional area of the void space 7 created between the crowns 3 and the barriers 10 is relatively large for optimisation of air flow and heat transfer.
  • the void area can be adjusted to suit the particular requirements of a building.
  • an underlap crown 8 is filled with insulation foam so that when overlapped on assembly with an overlap hook 9 of an adjacent panel (see especially Figs. 3 and 4), the panels at the joint can be readily jointed or stitched together. The compressive strength at the joint is enhanced.
  • Composite panels may be manufactured on a continuous production line by leading the outer sheet 2 along a flat bed with the recesses defined by the crowns 3 facing upwards.
  • the sheet 2 may be of metal such as thin gague steel.
  • the profiled sheet 2 is led to a lay-down area at which liquid foam reactants are spread across the sheet 2 using a lay-down poker or the like.
  • As the foam rises a backing sheet is applied over the foam and the sandwich thus formed is then led through an oven and subsequently cut to length.
  • the backing sheet 3 may be of metal such as thin gague steel.
  • the manufacturing technology is described in our UK-A-2227712, UK-A-2257086, and UK-A-2325640, the entire contents of which are herein incorporated by reference.
  • longitudinal conduit means 7 are defined by the foam.
  • a panel according to the invention is manufactured by leading an external sheet 2 along a flat bed defined by a conveyor having rollers 20.
  • a transverse support 21 is mounted by brackets 22 above the bed.
  • four anchor blocks 23 are mounted to the support 21 and a former 25 is mounted to each block 23 by screw threaded rods 26.
  • the longitudinal extent of a former 25 may be adjusted by moving the rod 26 relative to the associated anchor block 23.
  • the formers 25 remain static with respect to the moving profiled sheet 2.
  • Barriers which in this case comprise foil strips 10 are applied over the formers 25 and in this case are bonded to the inside face of the sheet 2 on each side of the profiled recess.
  • Adhesive 30 is applied to the inner sheet face by nozzles 31 which are supplied from a supply tank 32.
  • a suitable lubricant 35 is applied to the underside of the barrier strips 10 by brushes 36 supplied from a supply tank 37.
  • the lubricant assists the movement of the barrier strips 10 on the static formers 25.
  • Shaping rollers 40 shape the strips 10 to conform with the exposed profile of the formers 25.
  • liquid foam reactants are laid down over the applied barrier strips 10 and the upper face of the sheet 2.
  • a backing sheet 4 is applied and the foam is allowed to expand to fill the space between the sheet 2, barriers 10 and the sheet 4.
  • the formers 25 only extend for a length sufficient to allow the foam to at least partially set whilst supporting the barrier 10.
