Description
Insulated Boards and method of installing same This invention relates to insulated boards for insulating the inner and/or outer faces of the walls, preferably the external walls, of a building and to a method of installing such boards.
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 desire to reduce the impact caused by energy use in buildings and there is a continuous drive to improve the thermal efficiency of both old and new build buildings.
It is known to attach composite insulated boards to the inner faces of the exterior walls of a building to improve thermal efficiency of such walls, such insulated boards comprising a core of thermally insulating material sandwiched between substantially rigid outer layers. A plasterboard or other substantially rigid layer may be provided on an outer face of at least one side of the board, preferably the side forming an exposed face of the board.
A problem with such known composite insulated boards is that the various layers may not be completely aligned at the edges of the board. This can cause gaps to be formed between the insulating cores of adjacent boards when the outer layers are in abutment, leading to cold bridging and/or vapour and/or air infiltration through such gaps.
An object of this invention is to provide an improved insulated board and method of installation that will minimise any cold bridging, vapour and/or air infiltration between the masonry substrata and the inner face of the substantially rigid outer layer.
According to a first aspect of the present invention there is provided an insulated board assembly for attachment to a substrate, comprising at least two boards each comprising an insulating core having an least one outer layer, wherein said outer layer terminates short of the peripheral edge of the insulating core on at least two opposite sides of the board to define respective border regions devoid of said outer layer, at least one bridging piece being provided to be applied to said border region of adjacent boards to overlie the join between the insulating cores of said adjacent boards and to infill the gap between the outer layers of the adjacent boards formed by said border regions.
The outer layer may comprise a layer of plaster or a similar substantially rigid layer, such as fibre cement, Calcium Silicate or Magnesium Oxide board. Such layer may define an outer finishing layer of the assembly.
Said outer layer may terminate short of the peripheral edge of the insulating core around the entire periphery of the board to define a peripheral border region around the sides of the board.
In one embodiment, a peripheral edge region of said outer layer is of reduced thickness adjacent the respective border region of the board. Preferably the bridging piece is similar in thickness to said reduced thickness region of said outer layer.
A filling compound may be provided for application over the at least one bridging piece. A reinforcing mesh may be provided to be applied beneath the filling compound. The reinforcing mesh may be provided with an adhesive to permit attachment of the reinforcing mesh to the bridging piece. The filling compound is intended to be applied over the reduced thickness region of the outer layers of adjacent boards, where provided, to provide a substantially smooth and continuous bridging surface between the outer layers of adjacent boards.
One or more layers of tape may be provided to be placed below the or each bridging piece over the join between adjacent boards. Said tape may comprise a double sided adhesive tape for securing said at least one bridging piece to said border region of adjacent boards. Said tape may be provided with a release film removable prior to use. Said tape may be provided a rear face of the bridging piece for securing the bridging piece to the boards. Said tape may comprise a vapour and/or air impermeable membrane. Said tape may comprise a metallic foil. The tape may be provided with a release layer removable prior to use.
A further layer of tape, such a foil tape, may be applied over the join between adjacent boards before the bridging piece is applied thereto.
The bridging piece may comprise plasterboard, fibre cement, Calcium Silicate or Magnesium Oxide board. The bridging piece may comprise or incorporate a thermally insulating material.
According to a second aspect of the present invention there is provided a method of installing composite insulated boards, said boards comprising an insulating core having an least one outer layer, wherein said outer layer terminates short of the peripheral edge of the insulating core on at least two opposite sides of the board to define respective border regions devoid of said outer layer, said method comprising abutting at least two of said boards in side by side relationship and applying at least one bridging piece to said border region of adjacent boards to overlie the join between the insulating cores of said adjacent boards and to infill the gap between the outer layers of the adjacent boards formed by said border regions.
Said method may comprise applying a layer of tape over the join between the insulating cores of adjacent boards, beneath the at least one bridging piece.
A filling compound may be applied over the at least one bridging piece. A reinforcing mesh may be applied beneath the filling compound. The reinforcing mesh may be provided with an adhesive to permit attachment of the reinforcing mesh to the bridging piece. The filling compound may be applied over a reduced thickness region of the outer layers of adjacent boards, where provided, to provide a substantially smooth and continuous bridging surface between the outer layers of adjacent boards.
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 a join between adjacent insulated boards in accordance with an embodiment of the present invention; and Figure 2 is a detailed view of a bridging piece of the assembly of Figure 1.
As shown in the drawings, the present invention provides an improved method of joining adjacent insulated boards to minimise cold bridging through the join between adjacent boards.
Each insulated board 10a,10b comprises a laminated composite structure comprising a core 12 of thermally insulating material, such as expanded foam, aerogel, wood fibre or other high u value insulating materials, sandwiched between foil layers 13 and coated on at least one side with a plasterboard or MagnesiumOxide outer layer 14 to form a finished external surface of the board lOa,lOb, preferably an exposed surface of the board facing into a room of a building.
As can be seen in Figure 1, the outer layer 14 terminates short of the edge of the insulating core 12 on at least two opposing sides of the board to define a peripheral border region devoid of said outer layer 14. A edge region 15 of the outer layer 14 adjacent such border region is formed from a reduced thickness, as will be described in more detail below.
An elongate filler piece 16 is provided for overlying the border regions of adjacent boards 1 Oa, 1 Ob to cover the join between they insulating cores 12 of the adjacent boards. The filler piece 16 is formed from plasterboard or Magnesium Oxide board and is provided with a vapour and air impermeable double sides tape 18 on a rear side thereof covered by a removable release layer to enable the filler piece 16 to be attached to said border regions of the adjacent boards lOa,lOb between the respective outer layers 14.
In use, adjacent boards lOa,lOb are brought together so that there insulating cores 12 are brought into edge contact with one another. Such tight contact avoids cold bridging through the joint between adjacent boards lOa,lOb. The edges of the insulating cores 12 of adjacent boards lOa,lOb may be provided with cooperating tongue and groove formations or other interlocking or cooperating formations to provide an enhanced joint between the insulating cores 12.
Next a layer of tape 20, preferably a foil tape, is applied over the join between the adjacent boards lOa,lOb in said border regions of the boards. Next one or more filler pieces 16 (arranged end to end where more than one is required) are placed over the border regions of the adjacent boards lOa,lOb to overlie the join between the insulating cores 12 of the boards and to infill the gap defined between the outer layers 14 of the adjacent boards. The thickness of the filler piece 16 is substantially equal to the thickness of the reduced thickness edge regions 15 of the outer layers 14 of adjacent boards lOa,lOb.
Next a self adhesive reinforcing mesh 22 is applied over the one or more filler pieces 16, preferably overlapping the edge regions lSof the outer layers 14, and a filling compound 24 is applied to border regions of the boards 1 0a, I Ob to cover the joint between the adjacent boards and to create a smooth and continuous outer surface, the filling compound covering the filler piece 16 and the reduced thickness edges of the plasterboard layers of adjacent boards I Oa,1 0b.
The present invention provides a method and apparatus for assembly and forming joints between insulated boards that substantially presents cold bridging and provides a strong and seamless join between adjacent boards.
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.
