Abstract

The present invention provides a wallboard comprising a rigid decoratable facing layer provided upon its reverse face with a vapour barrier. A moisture resistant cushioning layer is laminated to the vapour barrier, said cushioning layer having a structural integrity such that on adhesion to a wall surface it both takes up both irregularities in the wall surface and firmly secures the wallboard thereto. The cushioning material may be corrugated and formed of a closed cell material.

Description

SPECIFICATION Wallboard The present invention relates to Wallboards used in the Construction Industry. Penetrating damp is a continuing problem in the Construction Industry particularly where solid (non-cavity) walls constitute the exterior of a building. Further it is often necessary to upgrade thermal conductivity of such walls to an acceptable level. Traditionally such solid walls are provided with a lining of a vapour proofed plasterboard affixed to a suitable framework of batons fixed to the brickwork on the inner surface of the exterior wall. Alternatively, exterior work such as tile hanging or rendering are required. Both these methods of upgrading the performance of exterior walls are expensive in both time and materials.The present invention seeks therefore to provide a composite wallboard which can be applied by means of adhesive to the interior surface of a wall; said wallboard serving both as an insulative and moisture penetration resistant member.
According to the present invention, therefore, there is provided a wallboard comprising a rigid decoratable facing layer provided on its reverse face with a vapour barrier; characterised in that a moisture resistant cushioning layer is laminated to the reflective layer said cushioning layer having a structural integrity such that on adhesion to a wall surface it both takes up irregularities in the wall surface and firmly secures the wall board thereto.
The rigid decoratable facing layer is most preferably impact-resistant, but by virtue of the vapour barrier need not be itself moisture resistant unless it is adapted for use in places of high relative humidity such as, for example, bathrooms and kitchens.
Suitable facing layers include fibre-board having a thickness of between 2 mm and 8 mm and commercially available wailboards which are generally flexible and light to carry. Of course, any facing layer may be utilised so long as it has the properties of lightness and the necessary rigidity to support the other members of the composite.
The reflective layer should be selected such that it is reflective on both surfaces as this assists in retaining heat within the building while repelling heat from the exterior. Suitable materials are vacuum metalised polyester, preferably double-sided, aluminium foil (9 microns or heavier) and vacuum metalised paper. Two sided vacuum metalised po lyester is preferred.
The cushioning member is added for insulation and to take up irregularities in the wall surface.
The cushioning member must be such that it can be adhered to the wall surface with readily aval- able glues, for example, Unibond ('Unibond' is a Registered Trade Mark). The cushioning member is preferably corrugated in order to assist in taking up irregularities and to provide, in some embodi ments, a channel against the reflective layer which may be disposed generally vertically. This channel allows moisture having penetrated a brick wall to which the wallboard has been affixed to escape downwardly; since in its absence such moisture would waterlog the cushioning member. Generally a closed cell construction is utilised since this acts in part as a vapour barrier and hence is a better insulator.Whatever materials are selected, such materials must have a surface strength to withstand the tensile/sheer stresses involved when the adhesive is bonded to a plastered or brick wall. Suitable choices are expanded low density polyethylene, expanded polystyrene and expanded polyurethane.
Generally expanded low density polyethylene (LDPE) is acceptable in corrugated form since it is both cheap and suitable in itself as a moisture barrier. It will be appreciated that the composite wallboards of the present invention can upgrade 9' solid brickwork to an acceptable thermal value while simultaneously providing excellent moisture repellent characteristics merely by the act of adhering these to an existing interior wall, even if the wall is substantially irregular. Thus, the use of such composites enables the previously required batons to be dispensed with. If the wallboard of the present invention is provided with a ready decorated surface comparatively little work is required to complete upgrading to the necessary degree.
One aspect of the present invention will now be described by way of illustration only with reference to the following examples.
Example 1 A 5 mm wallboard having a white decorative surface is provided on its reverse face with an adhesive layer to which was applied a sheet of double-sided vacuum metalised polyester. The sheet was smoothed over the surface and the adhesive allowed to dry. Subsequently further adhesive was applied to the remaining surface of the reflective vacuum metalised polyester and a layer of 4 mm corrugated low density polyethylene was firmly affixed thereto. The corrugation was parallel with the long edge of the wallboard. The so formed composite was then subjected to a firm pressure as by a roller or similar means to ensure a good structural integrity as between the various elements of the laminate.
Example 2 A composite wallboard as formed in the Example 1 was introduced into a Victorian dwelling having an exterior 9 inch wall which had originally been built utilising lime mortar. A measure of moisture penetration occurred during the year particularly in winter because of the exposure of this wall to the weather. The interior wall surface had, however, a sound plaster covering and consequently after removing the wallpaper etc. the wall was coated with Unibond and after a short period a number of wallboards cut to the requisite sizes were adhered to the wall with their long edges in abutment. A paper scrim was placed over the abutting joints and thick good quality lining paper was affixed over the composite boards. The lining paper was then decorated in standard fashion and observations were made over the ensuing months.
It was found that an insulation improvement of around 37% brings the 'U' value into favourable comparison with that obtained with an unfilled 11" cavity wall. Further no moisture penetration occurred.
It will also be appreciated that with a total thickness of between 5 and 8 mm it is often possible to line walls without the need to reposition architraves and skirting boards etc.. Accordingly, the present invention provides a facile means of upgrading the quality of solid brickwork without the necessity of plastering, rendering or framing. The invention therefore extends to wallboards per se, and to an improved method of building construction utilising the same.
