Abstract

Means and method of mounting heat insulation material on the outer surface 10 of a wall 1 [or like] (e.g. a "no-fines" concrete wall) consists of battens 3 which are affixed to the wall surface 10 in a spaced apart manner for receiving boards or panels 2 of heat insulating material (e.g. expanded polystyrene) located between them and against the wall surface (10). Outer members 30 of the battens 3 have a backing 31 of similar but more dense insulating material to maintain uniformity of insulation and also enable the composite batten 3 to bed against the wall surface. The battens (3) are secured by screws or studs 6 through clearance openings or slots 36 to permit relative movement between the battens 3 and wall 1. The battens 3 also provide mounting for outer cladding such as cement rendering 5 for which purpose mesh material 4 is secured to and spaced from the battens 3 to receive and reinforce the rendering 5. <IMAGE>

Description

SPECIFICATION Insulation mounting The object of this invention is to provide an improved method of and means for the surface mounting of insulation on walls or the like especially the exterior wall surfaces of buildings for heat insulation and also to counteract internal condensation. A particular object is to provide a mounting arrangementfor providing uniform overall insulation and which is capable of accommodating unevenness of the wall surface and which also accommodates to a considerable extent relative movement of the wall and insulation and any cladding of the latter due to temperature differences and other factors causing building structure movement. These and other practical advantages will be apparent from the following description.

According to this invention insulation mounting means is characterised by battens adapted to be affixed to a wall or like surface in a spaced apart manner for the location and retention between them of heat insulating material, e.g. in the form of boards or panels against the wall or like surface, the battens being backed with heat insulating material of a yieldable nature for maintaining heat insulation thereat and for bedding contact with the wall or like surface for accommodating unevenness of said surface.

Further in accordance with the invention the method of mounting heat insulation material on a wall or like surface is characterised by affixing the aforesaid battens in a spaced apart manner to the wall or like surface and locating between them the insulating material.

A practical example of the mounting arrangement is shown in the accompanying drawings in which: Figure lisa sectional plan view, of one form of the mounting arrangement.

Figure 2 is a detail plan view on an enlarged scale.

Figure 3 is a detail elevation prior to the application of outer cladding, Figures 4 and 5 are respectively a detail plan view and elevation showing a developed arrangement, and, Figures 6 and 7are detail views showing the mounting of alternative outer claddings.

Like parts are referred to by the same or similar reference numerals throughout the drawings.

In the practical application of the invention to the insulation of the outer surface of a wall 1 of a building such as a "no-fines" concrete wall, and referring firstly to Figures 1 to 3, the arrangement generally comprises panels or boards 2 of heat insulating material such as for example expanded polystyrene located against the outer surface 10 of the wall 1 between battens 3 secured to the latter, retaining means shown basically in the form of breather paper or as a waterproof membrane or sheathing 8 being secured to the battens 3. The paper or the like 8 extends across and retains the insulating material 2 in position and may be adhesively affixed to the insulation material 2.

The battens 3 are of composite form comprising firstly outer members or strips 30 of a material of adequate strength and durability for the purpose such as good quality wood and are shown of plywood, e.g. of marine quality or may be of hardwood. The rear or inner face of each member 30 has adhesively or otherwise affixed to it a backing layer 31 of insulating material of a yieldable nature such that the composite batten 3 is able to firmly bed against the outer surface 10 of the wall 1 and accommodate unevennes or irregularities within reasonable limits of the latter. Such bedding layer 31 may consist of insulating material of a more dense but similar nature than that of the boards 2 so that the insulation provided by the composite battens 3, is substantially the same as that afforded by the boards 2 in providing overall uniform insulation of the wall 1.The thickness and degree of insulation provided may be varied according to requirements.

The composite battens 3 are provided with holes 36 through them at suitable points along their length for receiving attachment or anchorage devices and which in the example shown in Figures 1 to 3 consist of screws 6 of stainless steel or other anti-corrosive material, each screw 6 passing through the batten 3 and into a bore 11 in the wall 1 receiving a fixing plug or resin grout 61.

Further, in accordance with this invention the holes 36 are of transverse elongate form to permit some lateral movement of the battens 3 in relation to the screws 6 in accommodating relative movement of the wall 1 and the insulation material 2 and other cladding as referred to below, e.g. due to temperature differences and/or other factors which cause movement in building structures.

The head of the screw 6 is shown accommodated in a recess or countersink 360 of corresponding elongate form in the outer face of the batten member 30 and preferably receiving an appropriate slotted washer 66 again of stainless steel or other corrosion resistant material.

The holes 36 may be other suitable form to provide clearance for limited movement of the battens relative to the screws 6.

After marking out and drilling the required screw holes 11 in the wall 1, e.g. with the aid of the battens 3, they are fixed in position and during assembly of the insulation serve to initially locate the boards 2 of insulating material against the surface 10 of the wall 1 with a side gripping action due to the elongation of the holes 36. The subsequently affixed breather paper or waterproof membrane or sheathing 8 then further serves to retain the boards 2 against the wall 1 and is secured to the battens 3 by means of stainless steel staples or other suitable noncorrosive securing devices.

The layer of breather paper or waterproof membrane 8 or other suitable sheet material is thus applied over the outer surface of the insulating material 2 and battens 3 which material 8 has either waterproofing properties or is vapour permeable/ moisture impermeable depending on the type of outer cladding selected.

Particularly where the outer cladding consists of cement rendering 5 as shown, reinforcing mesh material such as steel wire mesh 4 (Figures 1 to 3) is spaced away a distance from the outer faces of the insulating material 2, battens 3 and paper 8 by distance pieces or washers 70, e.g. of suitable material such as plastic material or "man made" synthetic fibre or resin, the mesh material 4 being also secured to the battens 3 by the staples 7 which pass through the distance pieces 70.

Also in the arrangement shown in Figures 1 to 3, the staples 7 may, in required instances, engage over a vertical stainless steel retaining wire 9 for further holding the mesh material 4 in position whilst each staple 7 preferably engages over the horizontal run 40 of the mesh material 4 about which is entwined stainless steel wire 44 in a known manner to stillfurtherensure support of the mesh material 4 having regard to the fact that the latter may be of less durable material.

The spaced away arrangement of the mesh material 4 is such that it is fully or almost entirely embedded in the cement rendering 5 so that such cladding is reinforced and firmly supported by the mesh material 4from the battens 3. The mesh material 4 may also provide secondary support of the insulation boards 2 if necessary.

At appropriate levels horizontally mounted cross members backed in the same manner may be secured to the wall to provide support for the lower edges of the boards 2 of heat insulating material and for other purposes such as prevention of fire spreading.

Referring to Figures 4and 5 the construction and arrangement is generally the same as that already described and the same or similar reference numerals are employed.

However, in this case non-metallic mesh material 4' is employed e.g. of plastic material or "man made" synthetic fibre or resin. Furthermore, each mounting device is shown in the form of a stud or bolt 6' insulated in a hole 11 containing resin grouting 61 and having a machine thread receiving a nut 60 which is tightened against an elongate plate washer 66' received by a transverse recess 360' in the outer face of the batten 3. As before the hole 36 for the stud 6' in the batten member 30 and insulation 31 is of transverse elongate form and together with the transverse recess 360' permits some lateral movement of the batten 3 relative to each stud 6'.

Local thickening or projection of the mesh material 4' i.e. at the intersections may serve to space it from the insulating material 2 and battens 3 instead of using spacing washers 70.

Instead of cement rendering other suitable cladding may be employed such as hung slates or tiles, cedar composition or other weather boarding, or protected metal and other sheet claddings or the like. Thus, as shown in Figure 6 tiles Tare hung on transverse laths or battens 300 secured to the vertical battens 3 and in Figure 7 weather boarding W is directly secured to the battens 3 with an intervening felt layer F.

As well as 5 the self accommodating nature of the batten support provided by means of this invention, the use of stainless steel mountings 6, 6', washers 66, 66' and, where necessary, other securing or retaining means resistant to corrosion ensures firm support of the insulation 2 and cladding for a long serviceable life probably of the order of twenty five years or more.
