Description

SPECIFICATION Insulation panels for use in roofing and walls for buildings, and roofs and walls incorporating the insulation panels Technical Field This invention relates to insulation panels for use in roofing and walls for buildings, and roofs and walls incorporating the insulation panels.

Disclosure of Invention According to the present invention there is provided for use in roofing or a wall of a building, an insulation panel made of high density mineral fibre and having set into each of its side edge faces a metal section extending the full length of the panel and flanged at both longitudinal edges with one flange engaging the inner face of the panel and the other penetrating the panel at an inclination towards the inner face of the panel.

Preferably, each metal section has substantially centrally intermediate in its depth an inwardlydirected longitudinal groove to complement the groove in the metal section into the opposed side edge face of an adjacent insulation panel and provides a duct for accommodating a vapour seal.

Alternatively each metal section may have a longitudinally extending return offset substantially centrally intermediate in its depth, one in counterpart of the other, to provide a joggle in cooperation with its counterpart in the metal section set into the opposed side edge face of an adjacent panel, or the side edge faces of the panel are complementarily longitudinally stepped and rabbetted and the metal sections are configured in conformity therewith.

Also, according to the present invention, a roof or wall comprises a plurality of similar panels as hereinbefore defined arranged end-to-end and side-by-side across purlins or rails, a plurality of laterally-spaced trapezoidal bars of mineral fibre on the outer faces of the panels, profiled metal sheets overlying the panels and the trapezoidal bars thereon and transversely shaped complementarily to the panels and trapezoidal bars transverse configuration, each profiled metal sheet being of length to cover an end-to-end row of panels and being in overlapping relationship with the or each adjacent profiled metal sheets, 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.

Brief Description ofDrawings Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig (1) is a vertical cross-sectional view through roofing or wall according to the present invention, and Fig (2) is a vertical cross-sectional view through a wall according to the present invention, the wall being turned through 1 800 for ease of illustration.

Best Mode of Carrying out the Invention Referring to Fig (1), 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 lowe parallel major faces, 12 and 13, respectively. On the upper face 1 2, there are located a plurality of laterally-spaced bars 14 of trapezoidal crosssection which are formed separately from mineral fibre and have their bases 1 5 adhesively secured to the upper face 12 of each panel. The upper face 1 6 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.

The lower face 1 3 of each panel 10 is covered by a sheet 1 7 of white painted aluminium foil or other metal, or wood, or plastics material, or glass-reinforced cement, the sheet 1 7 being bonded to the face 1 3 possibly by adhesive, but preferably by heat sealing.

Each panel 10 has set into each of its side edge faces a metal section 1 8 extending the full length of the panel 10 and flanged at both longitudinal edges. One flange 1 9, the lower flange is flush against the sheet 1 7 covering the inner or lower .face 13 of the panel 10 and the other flange 20 penetrates the panel 10 at an inclination 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 1 8 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 (1), the metal section 18 may extend over about three-quarters or less of the thickness of the panel 1 0 from the inner or lower face 1 3 of the panel 10.The metal section 1 8 has substantially centrally intermediate its depth an inwardly-directed longitudinal groove 21 which complements the groove 21 in the metal section 1 8 set into the opposed side edge face of the adjacent panel 10 and provides a duct for a vapour seal 22.

Each panel 10, at its ends, rests on top of adjacent purlins 23 of the roof supporting structure, and once the panels 10 are assembled, the profiled metal sheets 11 are placed on top of the panels 10. Each profiled metal sheet 11 has corrugations 24 corresponding to the bars 1 4 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 a 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 1 6 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.

With reference to the wall shown in Fig (2), 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.

In Fig (2) the bars 114 of trapezoidal cross section are much wider than the bars 14 of Fig (1) and the valleys between the bars are much narrower, there being indeed an interchange of dimensions between the two such that the profiled metal sheets 111 of Fig (2) correspond to the profiled metal sheets 11 of Fig (1) when inverted. Also, at each side of each panel 110 there is only a vertically and longitudinally divided portion of a bar 114, each such portion complementing the portion at the adjacent side of the adjacent panel when the panels 110 are juxtaposed in the construction of a wall. In this case, of course, the panels 110 are clamped between the profiled metal sheets 111 and rails 123 by self-tapping screws 125 which pass through the sheets 111 and the panels 110 into the rails 123.

Different forms of 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). In each case there are two double-flanged metal sections to be set into adjacent side edge faces of adjacent panels in a roofing or wall construction. The flanges in each case are the same as those of the Figs (1) and (2) metal sections, but the metal sections themselves are modified.

One metal section 1 8 or 11 8 may be formed with a centrally-located longitudinal round bottomed recess and the other metal section 1 8 or 11 8 with a centrally-located longitudinal projection of shape similar to the recess so as to enter the latter when the adjacent panels are juxtaposed.

Alternatively, one metal section 1 8 or 118 is formed with a centrally-located longitudinal Vshaped recess and the other metal section 1 8 or 118 with a centrally-located longitudinal projection of arrow-head section dimensioned to enter the recess when the adjacent panels are juxtaposed.

In another alternative, the arrangement is somewhat similar to that in Figs (1) and (2) but the inwardly-directed longitudinal grooves are Vshaped, the vapour seal accommodated in the resulting rectanguiar-section duct consequently being of rectangular section.

In a further alternative, the metal sections 1 8 or 11 8 are straight and fit flush together.

In yet another alternative, one metal section 1 8 or 11 8 is formed with a step adjacent to the flange 19 or 119 and the other metal section 18 or 118 is formed with a corresponding indent.

To provide for passage of day-light through a roof or wall, 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.

INDUSTRIAL APPLICABILITy As a result of the invention, roofing can be assembled or a wall can be built, easily, quickly and safely by skilled or semi-skilled labour. The problems associated with complex multicomponent 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. Moreover, the mineral fibre panels provide increased thermal and acoustic insulation, and they are proof against fire, moisture, rot and vermin. Furthermore, the double-flanged metal sections prevent the ingress of moisture between panels, and a flame barrier in the event of fire.
