Definitions

  • the present invention relates to the provision of an improved insulation panel suitable for use in the external thermal insulation of buildings and other structures.
  • the insulation of such low-cost buildings can be improved by applying secondary insulation.
  • the secondary insulation may be applied as an internal layer. This has the disadvantage of reducing the space within the structure requiring the provision of new wall and ceiling finishes
  • insulated rendering may be applied to the external walls and/or roof of the structure. These are of varying effectiveness and can be difficult to apply.
  • Conventional external insulated rendering panels are required to be at least 60mm thick to provide reasonable levels of insulation and require additional decoration after fitting.
  • Existing methods of internal or external insulation also have the disadvantage that they require modifications to be carried out to the structure of the existing building, increasing the cost and inconvenience to the occupant.
  • the present invention provides a planar laminated insulating panel, particularly suitable for use externally in the insulation of a building structure, comprising a layer of aerogel fibre composite material, sandwiched between first and second layers of a relatively flexible, in isolation, protective plastic sheet material, by bonding with an adhesive, said laminated insulating panel having sufficient rigidity in use so as to be self supporting.
  • the term self supporting in this context means that the insulating panels have sufficient rigidity to support their own weight without buckling or sagging, in use.
  • the panels when insulating (cladding) a wall, the panels have sufficient rigidity, resistance to bending, so as to present a smooth, generally non- undulating or sagging appearance even if the wall to which they are attached is somewhat uneven.
  • Insulating panels of the invention can be made in sizes up to 5m x 1.35m, or greater, and still be self supporting.
  • the insulating panel of the invention is particularly suited for the external cladding insulation of an existing structure, for example a 'mobile home' or a caravan.
  • the panels can find other uses, for example in internal insulation of a building.
  • the insulating panel of the invention comprises a sheet of an aerogel fibre composite.
  • Suitable aerogel fibre composite materials are available from Aspen Aerogels Inc of Northborough MA United States of America and sold under the trade name SpaceloftTM. These products combine a silica aerogel with reinforcing fibres to produce a flexible water repellent sheet material with exceptional insulating properties.
  • the use of aerogel fibre composites as insulation generally is described in W02006/091812 (Aspen Aerogels Inc. ) .
  • Aerogel fibre composite materials tend to be soft, deformable and somewhat friable and so susceptible to damage in handling and in use.
  • the layers of protective plastic sheet material provide weather resistant, waterproof, protective outer layers to the insulating panel.
  • the aerogel fibre composite sheet is protected from damage and wear which would reduce its effectiveness as insulator.
  • the plastic layer adjacent the wall provides a firm smooth substrate for the adhesive bonding between the wall and the panel. This makes fixing the panels to a structure, in on-site conditions, much easier than if the aerogel fibre composite sheet was to be itself directly bonded to the wall.
  • the sheet of aerogel fibre composite may be used in any thickness to produce the desired insulation level for the panel of the invention.
  • the insulating panel may include more than one sheet of aerogel fibre composite bonded together to provide an increased thickness .
  • Preferably a single 9mm thick sheet of aerogel fibre composite is employed. Sheets of this thickness have been found to produce the desired levels of thermal and sound insulation when panels of the invention are used to insulate a typical static 'park' or mobile home as described hereafter with reference to specific embodiments.
  • the first and second layers of plastic protective sheet material are thin, to minimise the overall thickness of the insulating panels.
  • each layer have a thickness of 4mm or less. More preferably they are 3mm thick or less. Desirably they are of 2mm thickness. Thinner layers may be employed provided the panels that result retain the required rigidity characteristics and provide appropriate insulation levels and durability for the intended use.
  • the first and second layers of protective plastic sheet may each have a different thickness. For example a thicker layer may be provided on the side of the panel that faces outwards, in use, to provide enhanced weather protection.
  • the protective plastic sheet material is of a PVC plastic material, desirably of a recycled and recyclable PVC plastic material.
  • Suitable 2mm thick PVC material is available from Novafloor of Co FIFA, Calais, France and sold under the trade name NovacladTM. This material has the advantage that it can be painted or coated with decorative rendering, to increase its durability and present an attractive appearance.
  • Particularly preferred insulating panels of the invention comprise a 9mm sheet of aerogel fibre composite with a 2mm layer of a PVC flexible plastic laminated to each face. This provides a 13mm thick fully water repellent insulating panel with excellent thermal insulation and sound attenuation properties.
  • the first and second plastic layers and the aerogel fibre composite sheet are bonded together by an adhesive to form the planar laminated insulating panel.
  • the adhesive employed is a polyurethane adhesive. More preferably the adhesive is a one component, water curable, polyurethane adhesive.
  • a suitable adhesive is used to bond the relatively flexible plastic layers to the, highly flexible, aerogel sheet a rigid panel is obtained. Thus panels particularly suited to cladding the exterior of a structure are obtained.
  • Suitable polyurethane adhesives include Sikaforce R TM - 7120 L40, a one-component, polyurethane based adhesive available from
  • a layer of adhesive of from 0.5mm to 1.0mm thickness is used.
  • the layers of adhesive provide a strong bond between each layer of plastic sheet material and the aerogel fibre composite, to give a suitably rigid panel.
  • the rigidity or stiffness of the panel means that simple overcladding of horizontal or vertical surfaces (walls or roofs) can be achieved without needing to remove or modify existing features such as window and door frames, fascias, soffits or vents.
  • the panels present a smooth planar finish to a structure, overlying any minor irregularities. They can readily be cut to fit round features such as window frames. When fitted the appearance of a smooth continuous wall or roof is obtained.
  • the panels of the invention are lightweight and easily attached by a suitable adhesive to the walls of a structure such as a mobile home, without adding substantially to the overall dimensions of the structure. Furthermore, a panel of the preferred materials has been shown to have good fire resistance (one hour prevention of frame spreading) and complies with the relevant building regulations. Use of other possible materials for the protective layers has been found to be less satisfactory for various reasons. Surprisingly, even when using the preferred type of adhesive, both 2mm plywood layers and 1.8mm glass reinforced plastic (GRP) layers produced panels that tended to buckle or give an undulating appearance when used to clad a wall. Furthermore, a panel with a plywood surface would require weatherproofing (e.g. by painting) . GRP layers present the additional problem that they cannot readily be painted to produce a desired decorative finish.
  • GRP glass reinforced plastic
  • the present invention provides a method of manufacturing a planar laminated insulating panel, particularly suitable for use externally in the insulation of a building structure, and having sufficient rigidity in use so as to be self supporting, comprising the steps of: providing a layer of an aerogel fibre composite material and bonding first and second layers of a relatively flexible, in isolation, protective plastic sheet material to each face of the said layer of aerogel fibre composite material.
  • the adhesive is a water curable, one component polyurethane adhesive, which is applied to one side of the first layer of protective plastic sheet material and wetted with water to activate it.
  • the layer of aerogel fibre composite is then applied to the activated adhesive layer and the second layer of protective plastic sheet material applied with the adhesive in similar fashion.
  • the method further includes the step of vacuum pressing the insulating panel assembly during the curing of the adhesive.
  • the vacuum pressing is carried out at a pressure of about 5 bar.
  • the vacuum pressing has the advantage of applying a consistent even pressure to the insulating panel during curing of the adhesive and has been found to result in a strongly bonded, rigid panel with even external surfaces.
  • a curing time of about two hours is required to fully 'set' the bonds between the layers of the panel .
  • the present invention provides an insulating system for a structure comprising: planar laminated insulating panels, particularly suitable for external use in the insulation of a building structure, comprising a layer of aerogel fibre composite material, sandwiched between first and second layers of a relatively flexible, in isolation, protective plastic sheet material, by bonding with an adhesive, said laminated insulating panel having sufficient rigidity in use so as to be self supporting; and edging sections, said edging sections being formed and arranged to frame the edge of a said panel in use of the insulating system.
  • the edging sections frame the edge of a panel, in use on a structure, enclosing the edge to prevent or reduce the ingress of air or moisture, thus maintaining the high thermal insulation properties of the aerogel fibre composite sheet.
  • the edging sections may be formed from any suitable weather resistant material. Extruded PVC section is preferred.
  • the edging sections may be snap-fit, channel or 'T' section in form to suit the framing required at any particular panel edge. For example, where a large expanse of wall is being clad with a number of insulating panels of the invention, they are laid substantially adjacent to each other on the wall to present a substantially continuous cladding surface.
  • the edging sections between panels may then be of a ⁇ T' section shape with the cross bar of the 1 T' forming a bridge between the edges of adjacent insulating panels as shown hereafter with reference to specific embodiments.
  • the insulating system of the invention may further comprise an adhesive for bonding the insulating panels to a structure in use of the system.
  • the adhesive employed is a single component, elastic, MS-polymer universal bonding adhesive such as SABATM Seal-tack 750 MC-
  • the present invention provides a method for insulating a building structure comprising the steps of: providing planar laminated insulating panels, said panels comprising a layer of aerogel fibre composite material, sandwiched between first and second layers of a relatively flexible, in isolation, protective plastic sheet material, by bonding with an adhesive, said laminated insulating panel having sufficient rigidity in use so as to be self supporting; and attaching said insulating panels to external surfaces of a said building structure.
  • said insulating panels are framed by edging sections and are laid on the external surface adjacent to each other so as to present a substantially continuous insulating layer.
  • said panels are attached to an external surface of the building structure by adhesive bonding.
  • Other means of fixing for example, screws or bolts passing through the panels may be employed, but these will tend to lead to some loss of insulation performance due to "thermal bridging" across the fixings employed.
  • a discontinuous layer of an adhesive is used to bond the insulating panels to the structure.
  • an adhesive may be applied in lines or discrete portions ('blobs') to either the panel or a wall or roof being insulated. The panel is then pressed to the wall/roof to attach it.
  • By applying the adhesive in a discontinuous layer an air gap is formed, where the adhesive is not present, between the surface of the wall or roof and the insulating panels. This has the effect of providing enhanced thermal and acoustic insulation to the structure.
  • Figure 1 shows schematically an insulating panel of the invention
  • Figure 2 illustrates the attachment of insulating panels and edging strips to a wall.
  • Figure 1 shows on insulating panel 1 of the invention in cross section.
  • the panel 1 comprises a 9mm thick sheet of an aerogel fibre composite sheet 2 sandwiched between two 2mm thick sheets of a recycled PVC plastic sheet material 4,6.
  • the PVC sheets 4,6 are bonded to the aerogel fibre composite sheet 2 by layers of a polyurethane adhesive 8,9 which has the effect of making the panel 1 sufficiently rigid so as to be self supporting.
  • the panel 1 has a total thickness of only about 13mm but provides the highly effective thermal and acoustic insulation properties indicated in the test results given hereafter.
  • FIG 2 shows schematically the use of two insulating panels 1, of the same form as that shown in Figure 1, in the insulation of a wall 10.
  • the panels 1 are bonded to the wall 10 by means of adhesive portions 12, leaving an air gap 14 between the wall 10 and the insulating panels 1 to give enhanced insulation.
  • a PVC 'T' section edging strip 16 provides a bridging seal between the two panels 1 and is attached to the panels 1 by means of a suitable adhesive (not shown for clarity) .
  • the insulating panels 1 and edging strips such as the T section example 16 constitute an insulating system of the invention.
  • Insulating panels of the invention of the form shown in Figure 1 and described above were fitted to the exterior walls of a typical static "mobile home" by the means shown in Figure 2 and described above. A layer of conventional internal loft insulation was also installed. Before fitting of the panels the external walls of the home were 60mm thick, comprising 10mm internal plasterboard, 20mm loose polystyrene in the timber frame void and an external facing board with cementatious render.
  • the mobile home fitted with the insulating panels of the invention was found to have a U value of 0.410 W/m 2 K, close to the currently accepted requirement for a conventionally constructed building of 0.35 W/m 2 K.
  • the panels and insulating system of the invention can provide exceptional thermal insulation to a structure, even those with such poor original insulation as found in a typical mobile home.
