Abstract
The base rail 2 comprises a base layer formed of thermally insulating material 4 and an outer protective layer. The outer protective layer includes a first planar 6 portion bonded to and covering an outer face of the base layer. A second portion 10 extends orthogonally and outwardly from the first portion such that it is co-planar with an upper face of the insulating material. The upper face and second portion form a base for an external wall insulation to be supported on. The rail may also include a third portion 14 extending upwardly from the second planar layer to form an outer lip that, in use, covers and retains a portion of the wall panel insulation. A water impervious damp proof layer 16 may be provided covering the upper face of the base layer and at least a portion of the second portion. The damp proof layer may be a plastic membrane or a settable liquid.
Description
Insulated Base Rail for Supporting External Wall Insulation This invention relates to an insulated base rail for supporting external wall insulation.
Insulation is added to buildings to conserve energy by preventing heat loss through floors, walls, ceilings and lofts.
With ever increasing fuel and energy costs there is a continuous drive to improve the thermal efficiency of both old and new build buildings.
It is known to attach composite insulated panels to the exterior walls (facades) of a building to improve the thermal efficiency and appearance of the building, such insulated boards typically comprising a core of thermally insulating material sandwiched between substantially rigid outer layers. A weatherproof render or other substantially weatherproof layer may be applied to or may be provided on an outer face of at least one side of the panel, preferably the side forming an exposed face of the panel.
External wall insulation by such external panelling is especially done in the field of modernising buildings. This solution leads to excellent heat insulation with a non-destructive intervention which is relatively rapid and economically advantageous.
Further, installation is done outside of the building and therefore does not interfere with normal activities inside the building and does not reduce the internal area of the building, unlike panelling applied to the interior walls.
Typically the external wall insulation panels are supported by means of a base rail, formed from either metal or PVC, which is attached to the wall to support a lower edge of the panels. Such base rails are typically formed with a U shaped profile, with a rear wall adapted to be attached to the wall, a bottom wall for supporting a lower edge of the external wall insulation panels and a from wall arranged to protect the front edge of the panels. A mesh may be attached to the rear wall to aid render adhesion.
It is important to make sure that the external wall insulation layer does not bridge the damp proof layer in the wall. The support rail must be located above the damp proof layer of the wall, otherwise water may be able to use the insulation to climb above the damp proof layer in the wall, causing rising damp where it wasn't a problem before. However, this leads to an uninsulated strip below the damp proof layer in the wall, leading to thermal bridging. Such uninsulated strip below the support rail may be covered by insulated panels after the base rail has been fixed to the wall. However, this is a difficult and time consuming process and can still lead to problems or moisture ingress past the damp proof layer of the wall. Even where additional insulation is installed below the base rail, the base rail itself may still cause cold bridging, particularly where the base rail is formed from metal.
An object of the present invention is to provide an improved base rail for supporting external wall insulation panels that overcomes the abovementioned problems.
According to the present invention there is provided an insulated base rail for supporting external wall insulation panels, said insulated base rail comprising a base layer formed from thermally insulating material and an outer protective layer formed from a weatherproof material, said outer protective layer having a first planar portion bonded to and covering an outer face of said base layer, and a second planar portion extending outwardly from said base layer perpendicular to said first planar portion such that said second planar portion is substantially coplanar with an upper face of said base layer such that said upper face of the base layer and an upper face of said second planar portion of the outer protective layer define a support surface for an external wall insulation panel when the base rail is secured to a wall.
Preferably said outer protective layer further comprises a third planar portion extending upwardly from an outer edge of said second planar portion thereof defining an outer lip adapted to overlie an outer face of external wall insulation panel supported by the base rail.
A water impervious damp proof layer may be provided covering the upper face of the base layer and at least at least a portion of the upper face of the second planar portion of the outer protective layer. The water impervious damp proof layer may coat said upper face of the base layer and the upper face of the second planar portion of the outer protective layer. The water impervious damp proof layer is formed from a plastic membrane or may be applied as a settable liquid.
Preferably the base layer is formed from a material having a higher u value, and therefore substantially lower thickness for a given level of thermal insulation, than the insulating core of adjacent insulating panels.
The base layer may be formed from one or more of high density expanded polystyrene, extruded polystyrene, Aerogel or vacuum insulated panels.
The outer protective layer is formed from a metal, such as steel or aluminium, or may be formed from a plastic or composite material, such as unplasticised polyvinyl chloride (uPVC) or glass reinforced plastic (GRP).
An insulated base rail for supporting external wall insulation panels in accordance with an embodiment of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:-Figure 1 is a perspective view of an insulated support rail in accordance with an embodiment of the present invention; and Figure 2 is a perspective view of the support rail of Figure 1 in use.
As shown in the drawings, a support rail 2 for supporting external wall insulation panels in accordance with an embodiment of the present invention comprises an elongate base layer 4 having a rectangular cross section formed from a thermally insulating material, such as high density expanded polystyrene, extruded polystyrene, Aerogel or vacuum insulated panels. Bonded to an outer face of the base layer is an outer protective covering 6 made from a metal, such as steel or aluminium, or a plastic, such as uPVC, or a composite material, such as glass reinforced plastic (GRP). The outer protective covering 6 has a first planar portion 8 dimensioned to fit over and cover an outer face if the base layer 4 to which it is bonded, a second planar portion 10 extending perpendicularly from an upper edge of the first planar portion 8 away from the base layer to extend in coplanar relationship with an upper face 12 of the base layer 4, such that the upper face 12 of the base layer 4 and an upper face of the second planar portion 10 of the outer protective covering 8 define between them a common support surface upon which external wall insulation panels may be supported, as will be described below in more detail.
The outer protective covering 6 includes an upwardly extending third planar portion 14 extending upwardly from an outer edge of the second planar portion 10 thereof to define an outer lip arranged to overlie an outer face of the external wall panel supported on the base rail.
A water impermeable built in damp proof layer 16 is provided on the upper face 12 of the base layer 4 and the adjacent upper face of the second planar portion 10 of the outer protective covering 8 to prevent the passage of moisture past the base rail 2. The damp proof layer 16 may be defined by a suitable polymeric membrane or sheet or may be applied to the base layer and outer protective covering as a settable liquid which subsequently dries to form said water impermeable layer.
In use, as shown in Figure 2, the base rail 2 is affixed to a lower region of an external wall 20 of a structure above the pavement or outside ground level 22 with the upper face 12 of the base layer 4 adjacent or slightly above the damp proof layer (damp proof membrane) 24 of the wall 20, and with the insulating base layer 4 of the base rail 2 in contact with and adhered or affixed to the wall.
External wall insulation panels 26 may then be affixed to the wall 20 with the lower edges of the lowermost panels resting on and being supported by the base rail 2.
The thermally insulating base layer 4 of the base rail 2 prevents cold bridging in the region below the damp proof layer 24 of the wall 20 while the built in damp proof layer 16 of the base rail 2 prevents damp from rising up past the base rail 2.
The invention is not limited to the embodiment(s) described herein but can be amended or modified without departing from the scope of the present invention.
