Description
SPECIFICATION
Insulation board
This invention relates to boards for use in building, and in particular to insulation boards suitable for use in the insulation of cavity wall constructions. In practice the present invention, although not restricted to such use, has particular application to insulation board of expanded polystyrene or similar insulation material, for example insulation board as sold under the very well known Regis"tered Trade
Mark AEROBORD.
The present invention provides a board of insulating material provided with a plurality of spaced apart wall tie location indicator means disposed along at least one edge of the board. Preferably the indicator means are slots which are equally spaced apart along the said at least one edge, and wherein the length of the said at least one edge is an integral multiple of the spacing between adjacent indicator means.
The insulation board used is preferably expanded polystyrene board and the insulation board, for the insulation of cavity wall constructions, is provided with the slots along one longitudinal edge thereof. In use at least selected slots locate and accommodate the stem members of respective wall ties, the number of slots provided allowing one to correctly space apart the wall ties used to com- ply fully with the appropriate official building regulations governing the use of wall ties in the construction of cavity walls. Building regulations relating to the use of wall ties in cavity wall construction vary from country to country. Accordingly the length of the insulation board may vary and the spacing between the slots may also be varied as appropriate to comply with local practices and regulations.
The invention will be understood from the following description of embodiments thereof given by way of example only with reference to the accompanying drawings in which:
Figure 1 is a perspective view of an insulation board according to the present invention;
Figure 2 is a front view of the insulation board of Fig. 1;
Figure 3 is an end view of the insulation board of Fig. 1;

Figure 7 is a schematic drawing similar to
Fig. 5 in which different wall tie spacings are indicated;
Figure 8 is a front view of a wall of insulation boards as assembled in use within a cavity wall, in which the wall tie positions are based on the slot spacings of Fig. 5; and
Figure 9 is a view similar to Fig. 2 showing another embodiment of the present invention.
The insulation board illustrated in Figs. 1-4 of the accompanying drawings is a moulded expanded polystyrene board 10 of rectangular shape provided on edges 11 and 12 with grooves 13 and 14 respectively and on edges 15 and 16 with a continuous tongue 17 and a slotted tongue 18 respectively. The tongue 18 has a plurality of equally spaced apart slots 19. The tongues and grooves are of complementary construction, permitting a plurality of boards to be arranged edge to edge in both the horizontal and vertical directions, each tongue 18 entering a groove 14 of a board immediately above it and each tongue 17 entering a groove 13 of a board immediately to the left.
In the construction of an insulated cavity wall it is usual to use both insulation boards and wall ties. In the present case a slot 19 in an insulation board 10 in a cavity wall can locate and accommodate the stem member of a wall tie of known construction, with the anchor ends of the wall tie on each of the inner and outer leaves of the cavity wall.
In the construction of cavity walls there are a series of building regulations governing all aspects of the construction work including the use of wall ties. The appropriate regulations currently in force in the Republic of Ireland may be stated in general terms as recommending the following guidelines on wall tie usage, namely:
(a) Where the cavity wall has a cavity width in the range 50-75 mm, the recommended horizontal wall tie spacing is 900 mm; the recommended vertical wall tie spacing is 450 mm; and there should be 2.5 wall ties per square metre.
(b) Where the cavity wall has a cavity width in the range 75-100 mm the recommended horizontal wall tie spacing is 750 mm; the recommended vertical wall tie spacing is 450 mm; and there should be three (3) wall ties per square metre.
(c) Where the cavity wall has a cavity width in the range 100-150 mm the recommended horizontal wall tie spacing is 450 mm; the recommended vertical wall tie spacing is 450 mm; and there should be five (5) wall ties per square metre.
Referring to Figs. 5 and 7 of the accompanying drawings there are illustrated in schematic form an appropriate wall tie spacing for a cavity wall of category (b), Fig. 5, and for a cavity wall of category (c), Fig. 7. If slots 19 are provided at 150 mm spacings on a 1200 mm long insulation board as shown in Fig. 6A then the correct combination of slots may be selected for locating wall ties at the correct spacing for either category of cavity wall.
Thus, if the spacing for cavity wall (b) is to be met then a wall tie is provided at every fifth (5th) slot (750 mm spacings), while if the spacing for cavity wall (c) is the criterion then a wall tie is provided at every third (3rd) slot (450 mm spacings).
Referring to Fig. 6B of the accompanying drawings, this drawing exemplifies wall tie spacings where the first wall tie slot 19 is provided at any point in the range 0-150 mm in from the left hand top corner of the insulation board as shown in the drawing. In Fig.
6B the first slot 19 is at 50 mm spacing from the said top corner of the insulation board and each further slot is at a spacing of 150 mm from the previous one. This format of wall tie slot spacings has the advantage that no slot is provided at the abutting joint of two adjacent insulation panels.
Referring to Fig. 8 of the accompanying drawings, there is shown a wall of insulation boards 10 assembled together, with the complementary tongue and groove engagement previously mentioned. The positions 20 of a plurality of wall ties are shown located in selected slots 19 and held in position by the engaging board edge 12. The provision of the slots 19 for location and accommodation of the stem members of wall ties allows a closely knit assembly of the insulation boards 10-with the tongues 17/18 of one board in proper engagement with the grooves 13/14 of the appropriate abutting boards. It will be readily appreciated that in the construction of a cavity wall, in order to ensure the proper construction of the cavity wall one should preferably provide a wall tie configuration having the staggered arrangement as illustrated in Fig.
8. The present invention with the slots provided at 150 mm spacings allows one to achieve the staggered configuration of wall ties while complying fully with the relevant building regulation relating to wall tie usage.
A further embodiment of the present invention envisages that the slots 19 may be provided along the grooved edge 12 of the insulation board 10 and that in this instance the tongue 18 be continuous. Referring to Fig. 9 of the accompanying drawings, it is also envisaged as a third embodiment of the present invention that rather than provide slots 19 in one or more edges of the insulation board there be provided a plurality of pairs of cuts 22 along the tongue 18 of the edge 16 of the insulation board 10, whereby the portions 21 of the tongue 18 between the cuts 22 may be broken off as appropriate to provide the required slots to locate and accommodate the wall ties. In this embodiment, in use, slots 19 are therefore made or formed on the insulation board on site by breaking away tongue portions 21. The cuts 22 may alternatively be formed along the grooved edge 12.
It is also envisaged that each board be provided, at say the mid point of its in use vertical edges, with a clear mark 23. These marks 23 may be used in practice, once the bottom insulation boards are properly bedded and aligned, to assist the brick/block layer to ensure that the wall under construction is correctly aligned and that the correct brick/block line is being followed. It is also envisaged that the wall tie location indicator means may simply consist of marks along the edge(s) of the board where wall ties may be placed in use.
It will be readily appreciated that while the embodiments described above make reference to the provision of slots along one edge only of the insulation board and that edge being a longitudinal edge of the board, the present invention is not in any way limited to such a slot configuration. The insulation board may be provided with spaced apart slots on more than one edge of the insulation board namely both the in use assembled horizontal and vertical edges of the insulation board.
The present invention has a number of important advantages for both the building of a cavity wall and the insulation of the cavity wall. It will, for example, be readily appreciated that the provision of the slots or other wall tie location indicator means in the insulation board provides a ready means to properly locate the wall ties, as the wall is being constructed, resulting in the correct location and use of the proper number of wall ties without the need to measure off, on site, the distances for spacing apart the wall ties. The position and number of wall ties used can be easily checked by the site supervisor or the architect. Greater safety is achieved by substantial elimination of possible errors in providing the correct number of wall ties and a reduction in wastage by substantial elimination of over usage of wall ties.It will be further appreciated that, in the preferred embodiment, the brick/block layer does not have to interfere with and possibly damage the insulation board by having to cut slots in the board on site.
The provision of the slots on the insulation board allows all known types of wall ties to be used-for example the well known wall ties sold under the Registered Trade Mark
AEROTIE. The tongue and groove engagement of the insulation boards with the slots provided, allow proper engagement between the insulation boards, without any holes or gaps in the insulation board assembly resultant upon poor on-site cutting of slots or holes to accommodate wall ties. This means that heat losses are minimised and that instances of cold bridging are substantially eliminated.
It will be understood that if the first slot is placed 75 mm from one corner of the board and each of the other slots are positioned 150 mm apart, then one can achieve the required wall tie positioning to comply with the stated building regulations and achieve an advantageous result that no wall tie is positioned at the joint of two engaging or abutting boards.
If an insulation board according to the present invention is produced from expanded polystyrene using a moulding process, the insulation board has an overall skin which renders the board to a large extent water resistant, including a skin in the moulded slots for the wall ties. The use of the moulding process improves the water resistance of insulation board which is provided with preformed slots to locate and accommodate wall ties.
It will be readily appreciated that while the described embodiments relate to insulation boards provided with tongue and groove edges to facilitate engagement with other similar insulation boards, the present invention may also be applied to insulation boards having plain edges and/or rebated edges or where assembly of the insulation boards in use is a simple abutment or interlock of one edge of one board upon an edge of the immediately adjacent board. One or more of the plain edges of an insulation board may according to the present invention be provided with spaced apart slots or provided with spaced apart cut away portions which may be broken away to provide slots.
