Definitions

  • This invention relates to insulation panels for use in roofing and walls for buildings, and roofs and walls incorporating the insulation panels.
  • Pre-insulated roofing and wall panels have come into wide use for the weathering and insulation of many types of building and are commonly referred to as composite or bonded insulation panels or sheets.
  • foam plastics material is injected between two layers of metal or membrane.
  • a bonded insulation panel is a profiled metal sheet with a layer of foam plastics insulation material bonded to the underside.
  • jointing sections including plastics and metal sections
  • plastics and metal sections have been utilised to join insulation panels side-by-side.
  • These jointing sections have normally been provided for aesthetic reasons in that they have hidden the joints between panels.
  • There is, however, a problem associated with such joints in providing an effective vapour seal which prevents warm moist air passing through the joint and condensing on the cold surface of the outer metal or plastics weathering sheet. When condensation occurs, the resulting liquid can drip through the joint into the building. Serious problems of condensation occur when voids in the construction are reacted as is the case in bonded panels.
  • foam plastics insulating materials which are dimensionally unstable and, when applied to metal sheets, the considerable differences in coefficients of expansion of the two materials lead to breakdowns in adhesion of the insulation to the metal sheets.
  • a major disadvantage of foam plastics insulating materials is that they are thermally decomposable to liberate toxic and noxious fumes with emission of dense smoke.
  • U.S.A. Patent Specification No. US-A-2,142,305 discloses gypsum panels having on each of two opposite edges complementary metallic elements.
  • the gypsum panels are precast and may be reinforced by mineral fibres which are admixed with the liquid cementitious material prior to casting of the latter.
  • the metallic elements are keyed to the opposite edges of the panels during the pouring of the cementitious material.
  • the metallic elements extend the full length of the panel and are flanged at their longitudinal edges, with the flanges extending parallel to major faces of the panels and lipped at their free edges to key into the cementitious material when the latter is poured to cast the panels.
  • the flanges are usually flush with the major faces of the panels but one or both of them may be embedded in the cementitious material so that it is not exposed on the outside of the slabs.
  • the complementary shaping of the two metallic elements on opposite sides of a panel is intermediate the depths of the elements, i.e. at positions spaced from both flanges.
  • a flange is not provided at the embedded edge of the metallic element shaped to provide a groove, and, instead, the length of metal at the groove opening side remote from the flush flange is bent back and splayed relative to the flush flange.
  • the metallic elements are fast with the cast cementitious material in panels in accordance with U.S.A. Patent Specification No. US-A-2,142,305. Thus there are cold bridges between the two materials with temperature transfers between the two materials.
  • French Patent Specification No. FR-A-2,317,429 also discloses metallic element used with poured or cementitious materials which subsequently sets around the metal sections, adjacent metal sections of adjacent units being set apart leaving a gap into which an elastic or non-setting material may be poured to create a movement joint.
  • the principal object of the present invention is to provide an insulated roof and wall cladding panel of a two-stage construction which eliminates the need for bonding the panel forming high density mineral fibre material to metal sections on each of the two opposite side edges thereof.
  • an insulation panel for use in the roofing and/or the cladding of walls of buildings and provided on each of its two opposite side edges with a metal section which extends the full length of the panel and is flanged at both longitudinal edges with.
  • one flange flush against a major face of the panel and the other flange penetrating the panel material is characterized in that it is made of high density mineral fibres, is formed in each of its opposite side edge faces intermediate the depth thereof with ah inwardly-directed longitudinal groove and, between the groove and the major face intended to be outermost when the panel is in use, with a longitudinal slot also extending the full length of the panel but inclined in the direction of its depth towards the other major face of the panel, and in that the web of each metal section is shaped for endwise fitment to the respective side of the panel and has intermediate its width an inwardly-directed groove which fits in the groove in the respective side edge face of the panel with one flange then flush against said other major face of the panel and the other flange fitting into
  • the metal sections are not bonded to the mineral fibre panel, they are free to move relative to the latter on expansion or contraction of the metal sections as a result of temperature changes.
  • a roof or wall cladding comprises a plurality of similar panels as hereinbefore defined arranged end-to-end and side-by-side across purlins or rails, a vapour seal in each duct formed by adjacent and mutally-complementing, inwardly-directed grooves formed by the webs of adjacent metal sections fitted to adjacent panels, a plurality of laterally-spaced and parallel bars of trapezium cross-section and of mineral fibre of full panel length overlying and adhered through their bases to the outer faces of the panels, profiled metal sheets overlying the panels and the trapezium-section bars thereon and transversely shaped complementarily to the panels and trapezium-section bars transverse configuration, each profiled metal sheet being of length to cover end-to-end row of panels and being in overlapping relationship with the or each adjacent profiled metal sheet, rivets securing the profiled metal sheets together at the overlapping portions, and means clamping the panels between the profiled metal sheets and the purlins or rails.
  • roofing consists generally of a plurality of mineral fibre panels 10, and a plurality of profiled metal sheets 11 overlying the panels.
  • Each of the panels 10 is rectangular in plan view and in cross-section and has upper and lower parallel major faces, 12 and 13 respectively.
  • On the upper face 12 there are located a plurality of laterally-spaced bars 14 of trapezium cross-section which are formed separately from mineral fibre and have their bases 15 adhesively secured to the upper face 12 of each panel.
  • the upper face 16 of each bar 14 is flat and parallel to the base 15, thereof, and the side walls are convergent upwards towards the upper flat face.
  • the bars 14 are parallel to one another and extend over the full length of each panel 10.
  • each panel 10 is covered by a sheet 17 of white-painted aluminium foil or of other metal, or of wood, or of plastics material, or of glass-reinforced cement, the sheet 17 being bonded to the face 13 possibly by adhesive, but preferably by heat sealing.
  • Each panel 10 has set into each of its side edge faces a metal section 18 extending the full length of the panel 10 and flanged at both longitudinal edges.
  • One flange 19, the lower flange in Fig. 1 is flush against the sheet 17 covering the inner or lower face 13 of the panel 10 and the other flange 20 penetrates the panel 10 at an inclination in the direction of its depth towards said inner or lower face 13 of the panel, a slot being provided for the latter purpose in the side edge face of the panel 10.
  • the flanged metal section 18 is fitted endwise to the panel 10 and is held against displacement laterally outwards of the latter by virtue of the inclined flange 20. As can be seen in Fig.
  • the metal section 18 may extend over about three- quarters or less of the thickness of the panel 10 from the inner or lower face 13 of the panel 10.
  • the metal section 18 has substantially centrally intermediate its width an inwardly-directed longitudinal groove 21 which complements the groove 21 in the metal section 18 set into the opposed side edge face of the adjacent panel 10 and provides with the latter groove a duct for a vapour seal 22.
  • Each profiled metal sheet 11 has corrugations 24 corresponding to the bars 14 on each panel so that the bars 14 fit into the corrugations 24, and each profiled metal sheet extends from top to bottom of an end-to-end row of panels 10.
  • the panels 10 are clamped between the metal sheets 11 and the purlins 23 by self-tapping screws 25 which pass through the sheets 11 and the panels 10 into the purlins 23, the screws 25 being fitted with sealing washers 28.
  • Each sheet 11 extends throughout the width of the panel 10 and has a laterally projecting extension 26 which overlaps the sheet 11 overlying the adjacent panel 10 and is of partial valley formation and engages over and around the upper face 16 of the adjacent bar 14 of the adjacent panel.
  • the overlapping portions of the metal sheets 11 may be secured together by rivets 27, or self-tapping screws.
  • Each panel 10 may, for example, be 600 mm to 1000 mm in width and max 3000 mm long, and may have bars spaced at 75 mm to 300 mm: the thickness of each panel may be 30 mm to 120 mm and the thickness of each bar may be 20 mm to 120 mm.
  • the arrangement is basically the same as the roofing shown in and described with reference to Fig. 1 and corresponding parts are denoted by the same reference numerals increased by. one hundred.
  • double-flanged metal sections may be set into the side edge faces of the panels 10 and 110 instead of the metal sections 18 and 118 shown in Figs. 1 and 2.
  • the flanges in each case are the same as those of the Figs. 1 and 2 metal sections, but the inwardly-directed longitudinal grooves are modified, for example, they may be V-shaped, the vapour seal accommodated in the resulting rectangular-section duct consequently being of rectangular section.
  • any panel 10 of the roofing of Fig. 1 may be replaced by a light-transmissive panel, the profiled metal sheet 11 and panel 10 being replaced by profiled translucent or transparent sheets of reinforced glass fibre or plastics material spaced apart by mineral fibre spacer units occurring at each purlin or rail and incorporating condensation drainage grooves.
  • An advantage of the present invention provides a two-stage panel construction which eliminates the need for bonding the mineral fibre to the metal weathering sheet.
  • a further advantage is that the metal sheets can expand and contract over the insulation panels without problems of delamination associated with fully bonded foam plastics.
  • non-combustible mineral fibre obviates the disadvantages of foam plastics materials and provides high heat-insulating qualities.
  • the integrated longitudinal metal support sections provide a novel support and vapour seal joint between panels. The construction contains no voids in which condensation can form.
  • the invention produces a simple installation procedure and ensures total insulation integrity.
  • roofing can be assembled or a wall can be clad, easily, quickly and safely by skilled or semi-skilled labour.
  • the problems associated with complex multi-component in situ assembled systems or known roof panels comprising profiled metal sheets insulated with foamed polystyrene or polyurethane are avoided, especially the danger of fire, dense smoke and toxic fumes in the event of fire.
  • the mineral fibre panels provide increased thermal and acoustic insulation, and they are proof against fire, moisture, rot and vermin.
  • the double-flanged metal sections prevent the ingress of moisture between panels, and provide a flame barrier in the event of fire.
