Description
Insulation Product
This invention relates to an insulation product.
A known insulation product for use in roofing comprises a waterproof facing on which a board of relatively thick and rigid insulation material is mounted. To enable that product to be rolled up for convenience of storage and transportation, the waterproof facing is flexible and the surface of the board of insulation material remote from the waterproof facing is provided with a series of parallel slots. When the facing is rolled up with the board outermost, the insulation board breaks at the base of the slots to form a series of parallel blocks. Although the slots have the advantage of enabling the product to be rolled up, they have the serious disadvantage of providing paths through which heat can escape between the adjacent blocks of insulation material, with the effect that the insulating performance of the product is reduced.
It is an object of the invention to provide an insulation product that is simple to manufacture and can be rolled up but does not suffer from the above-mentioned disadvantage of the prior art.
The present invention provides an insulation product comprising a plurality of like blocks of insulation material secured side by side on a flexible facing so that the product can be rolled up with the blocks outermost, each block having a lateral projection running substantially the length of the block and arranged to overlap part of the side of an adjacent block when the facing is unrolled and flat.
In use, when the facing is laid on the surface to be insulated, the overlap creates a relatively long path for heat to follow, and the path does not lie normal to the surface to be insulated. As a result, heat cannot so easily pass through the insulation product and the heat loss is reduced.
In a particularly simple arrangement, the projection may simply overlie the side of the adjacent block.
Preferably, however, the adjacent block has a recess for receiving the projection. More preferably, the recess is of complementary shape to the projection. In that way, the adjacent blocks form a joint, which helps keep the adjacent blocks in position and also defines a relatively long and meandering path for heat to follow.
The projection may be in the form of a tongue projecting from either the base portion of the block or from the distal portion of the block. The tongue may be of rectangular cross-section. That is an especially simple form of joint which is easy to manufacture.
The projection may be in the form of a tongue projecting from the central region of the block.
Preferably, the tongue tapers towards its distal end.
More preferably, the tongue has a cross-section in the form of a trapezium. It has been found that this arrangement gives good performance in rolling up, unrolling and preventing heat loss. Preferably, the length of the projection is between 0.5 cm and 3 cm, more preferably between 1 cm and 2 cm. Preferably, the width of the projection is between 1 cm and 3 cm.
Alternatively, the tongue may have an arcuate cross-section. Such a section is somewhat less easily damaged by careless handling.
Preferably, when the product is unrolled flat the gap between the projection and the surface of an adjacent block is less than 1.5 mm. Advantageously, the gap is substantially zero. The smaller the gap between adjacent blocks, the less heat will escape from the surface to be insulated on which the product is laid.
One end of each block may have an end projection arranged to overlap part of one end of an adjacent block in another such insulation product when the two products are laid side by side. Again, the overlap creates a relatively long path for heat to follow and the path does not lie normal to the surface to be insulated. As a result, heat cannot easily pass through the insulation product and thermal performance of the product is again increased. Preferably, the end projection overlies the end of the adjacent block. In that way, it is easier to lay insulation products side by side, for example, on an adhesive surface. Preferably, the opposite end of each block has a recess which is of complementary shape to the end projection. Again, the recess in combination with the projection on adjacent insulation products provides a joint which reduces further the escape of heat.
The end projection may project either from the base portion of the block or from the from the distal portion of the block. Such an end projection is preferably of rectangular cross-section. Alternatively, the end projection may taper towards its distal end.
Preferably, the length of the projection is between 0.5 cm and 3 cm, more preferably between 1 cm and 2 cm.
Preferably, the width of the projection is between 1 cm and 3 cm.
The flexible facing may have a thickness between 0.05 mm and 5 mm, or between 0.1 mm and 1 mm.
The flexible facing may comprise roofing felt, or may be a polymeric material.
The insulation material may be a rigid plastics foam, such as expanded polystyrene, extruded polystyrene, polyurethane foam or phenolic foam, or it may be rigid mineral wool.
Preferably, the length of the blocks is in the range of 50 cm to 150 cm.
Preferably, the depth of the blocks is greater than 2 cm.
Preferably, the width of the blocks is in the range of 5 cm to 15 cm.
Preferably, the blocks are adhesively secured to the flexible facing. In that way, the blocks can be attached to the facing in a simple manner.
Examples of insulation products in accordance with the invention will now be described with reference to the drawings of which:
Fig. 1 is a plan view of an insulation product;
Fig. 2 is an end view of a pair of adjacent blocks of insulation material forming part of the insulation product shown in Fig. 1;
Fig. 3 is a side view of the insulation product shown in Fig. 1 and Fig. 2 after it has been rolled up;
Fig. 4 is a longitudinal cross-section of a pair of blocks, in a modified version of the insulation product shown in Figs. 1 to 4, shown laid side by side;
Fig. 5 is an end view of a pair of blocks of a second form;
Fig. 6 is an end view of a pair of blocks of a third form;
Fig. 7 is an end view of a pair of blocks of a fourth form; and
Fig. 8 is an end view of a pair of blocks of a fifth form.
Referring to the accompanying drawings, Fig. 1 and
Fig. 2 show an insulation product indicated generally by the reference numeral 1 comprising a plurality of like blocks of insulation material 2 of expanded polystyrene and a flexible facing in the form of a facing 3 of roofing felt material. The blocks 2 are arranged sideby-side and extend across the width of the facing 3 which is shown lying flat. Each of the blocks 2 is attached to the facing 3 by means of a suitable adhesive (not shown).
As can be seen from Fig. 1 and Fig. 2, each block 2 has two rectangular, parallel end faces 4, a rectangular top face 5 which is parallel to a rectangular bottom face 6 and two side faces 7, 8. For each block, the length of the block is approximately 90 cm, the width of the block on the bottom face is 10 cm and the thickness of the block is 5cm.
As shown in Fig. 2, which shows a pair of blocks seen from the end, the first side face 7 of each block is formed with a central, lateral projection 9 extending along the length of the block 2. The projection 9 is in the form of a tongue which tapers towards its distal end with a cross-section in the form of a trapezium. The width of the projection 9 at its widest point is 2.5 cm, while its width at the narrowest point is 1.6 cm. The length of the projection is 1 cm.
The second side face 8 of the block 2 is formed with a central recess 10 which extends along the length of the block 2. The recess 10 has a shape that is complementary to the shape of the projection 9 on the first side face 7; thus the recess 10 has a cross-section in the form of a trapezium with the same dimensions as the projection 9.
Each block 2 of the insulation product has a shape which is identical to the block shown in Fig. 2 and described above. As shown in Fig. 1, the blocks 2 are arranged side-by-side so that, when the facing is flat, the projection on each block is received by the recess on the adjacent board. In that way, the lateral projection 9 on each block 2 overlaps a part of the side of an adjacent block. The gap between adjacent blocks 2 is minimal when the facing 3 is unrolled flat.
Fig. 3 shows the insulation product after it has been rolled up for storage or transport. As shown in
Fig. 3, when the product is rolled up, for each pair of adjacent blocks, the facing 3 folds along the line where the two blocks meet. That causes each adjacent block 2 to rotate about that line in opposite directions and thus the centre of each block moves away from the centre of each adjoining block. The shape of the projections 9, and the corresponding recesses 10, are such that the adjacent blocks 2 disengage when the facing 3 is rolled up.
When the facing 3 is unrolled again for use, the corresponding projections 9 and recesses 10 on adjacent blocks re-engage, and the insulation product 1 reassumes the arrangement shown in Fig. 1. In use, there is little or no gap between adjacent blocks 2 and so the amount of heat that can pass through the insulation product 1 from the surface to be insulated is reduced.
In a modified version of the insulation product 1, the shape of each block 11 of insulation material is as described above with the addition of a distal projection 12 on one end face of each block and a recess 13 on the base part of the opposite end face of each block. The projection 12 on the end faces has a rectangular crosssection. The recess 13 on the end faces is complementary to the end projection 12 and thus also has a rectangular cross-section. The projection is 2.5 cm wide and 2.8 cm long.
As shown in Fig. 4, which shows a cross-section of two such modified insulation products 11 lying side by side, when two lengths of the modified insulation product are laid side by side (so that the blocks in each length of product are end to end), the projection 12 on the end face of each block 11 fits into the corresponding recesses 13 on the neighbouring block on the neighbouring length of insulation product so that adjacent blocks overlap each other. In that way, there is little or no gap between adjacent lengths of insulation product when they are laid and heat loss from the surface to be insulated is reduced.
Fig. 5 shows a pair of blocks 14 having an alternative form to those shown in Figs. 1 to 6 attached to the facing. Each block 14 has the same shape as the block 14 shown in Figs 1 to 3, except that the central projection 15 is semi-circular in cross-section. A complementary recess 16 is provided on the opposite, second side face.
Fig. 6 shows a pair of blocks 17 in a further alternative form. A projection 18 is provided on the distal portion, (that is to say the outer half with respect to the facing) of the first side face of each block. The projection has a rectangular cross-section.
A complementary recess 19 is provided on the opposite, second face of the block.
Other possible forms of blocks 20, 21 and 22 of insulation material are shown in Figs. 7 and 8.
In Fig. 7, the projection comprises merely a slanting side face that overlies a complementary face on the adjacent block.
In Fig. 8, alternate blocks 21 are formed with a respective projection 23 on each side, while the intermediate blocks 22 are formed with a respective complementary recess 24 on each side.
The blocks can be made from virtually any suitable insulation material, for example, a rigid plastic foam such as expanded polystyrene (as already described), extruded polystyrene, poyurethane foam, and phenolic foam, or rigid mineral wool batts. Similarly, the blocks can be attached to any suitable flexible sheet material, for example, roofing felt, a polymeric material, such as polyethylene, or a paper product.
The dimensions of the blocks and the flexible sheet can be chosen according to the application. The invention can be used, for example, in roofing insulation or in insulating damp proof courses. The good thermal properties of an insulation product embodying the invention enable it to be used in a damp proof course in place of the conventional relatively thin flexible insulants.
