Description

An insulating panel and a construction on a structural element of a building
Field of the Invention
The present invention concerns an insulating panel for use in a construction on a structural element of a building, such as a floor, ceiling or the like. The invention also concerns constructions incorporating such insulating panels.
Background of the Invention
A known type of floor construction, in particular for a suspended floor, is disclosed in GB 2501883 A, published 13 November 2013. The floor construction comprises a plurality of concrete beams, which provide load-bearing support for the floor. The floor then comprise multiple layers including for example a moisture-proof membrane, concrete screed, supporting mesh, carpet and the like, together providing the usable surface of the floor.
The beams of the floor construction are shaped in such a way as to have a ledge extending from each bottom edge, giving them an inverted T-shape. The floor construction further comprises insulating panels, arranged underneath the floor, of expanded polystyrene. The insulating panels are shaped correspondingly with a flange extending from each top edge, so that each insulating panel is held in place between two adjacent beams with the flanges of the panel resting upon the ledges of the beams. In addition, further infill panels are provided underneath the beams, so that a complete insulating layer is provided between and underneath the beams 2.
However, it is a disadvantage that the insulation provided by the insulating panels can be less than would be preferred. In particular, cold bridges can be formed between the concrete beams and the surface of the floor, through which heat can be lost. While it is known to place a further layer of insulating panels over the concrete beams, this makes the construction more complicated. In addition, further insulating panels with sufficient insulating properties to prevent cold bridges forming between the concrete beams and the surface of the floor can be prohibitively expensive.
The present invention seeks to mitigate the above-mentioned problems. Alternatively and/or additionally, the present invention seeks to provide improved insulating panels and improved constructions on structural elements of buildings.
Summary of the Invention
In accordance with a first aspect of the invention there is provided an insulating panel for a construction on a structural element of a building, the structural element comprising a plurality of beams, the insulating panel comprising: a first insulating portion formed of a first material, arranged to be positioned between first and second adjacent beams of the plurality of beams, and to sit upon ledges extending from the first and second adjacent beams; and a second insulating portion formed of a second material with different properties to the first material, wherein the second insulating portion is connected to the first insulating portion and arranged to be positioned over the first adjacent beam when the first insulating portion is sat upon the ledges extending from the first and second adjacent beams, and wherein the first insulating portion is fixed to the second insulating portion by means of an indentation in a side of one of the first insulating portion and the second insulating portion receiving a corresponding extended portion on a side of the other of the first insulating portion and the second insulating portion.
As the second insulating portion is positioned over the first beam, it separates the first beam from any floor layers above the beams, so improving the insulation of the floor. In particular, the second insulating portion will help prevent any cold bridges between the beams and the floor. To achieve this, no additional layer of insulating panels is required, as the insulation is provided by the first insulating portions positioned between the beams, and the second insulating portions positioned over the beams. Further, as the first and second insulating portions are formed of different materials having different properties, the materials used can be selected to suit the conditions the first and second insulating portions will undergo. In particular, when used in a flooring system the second insulating portion will provide load-bearing support for the floor via the first beam, while the first insulating portion will not provide any such load-bearing support, and so the materials used can selected appropriately. However, despite the use of different materials for the first and second insulating portions, as the portions are provided together as a single insulating panel, construction using the insulating panels is simple and the number of different types of insulating panel required to provide insulation including a layer over the beams is reduced.
Further, having the first insulating portion fixed to the second insulating portion by means of an indentation in a side of one of the first insulating portion and the second insulating portion receiving a corresponding extended portion on a side of the other of the first insulating portion and the second insulating portion, allows the first and second insulating portions to be fixed together without glue being required, as the extended portion is held within the indentation by friction between the exterior surface of the extended portion and the interior surface of the indentation, provided an "interference fit". This makes construction of the insulating panels simpler and quicker, as time for the glue to cure is not required.
The structural element may be a floor or a ceiling, for example. The structural element may be a suspended floor. The beams may be concrete beams. The surface of the structural element on which the holder is mounted may be the interior surface of a room.
Preferably, the surface of the part of the first insulating portion extending beyond the first and second beams is at the same level as the surface of the second insulating portion opposite the surface facing the first beam. This allows the insulating panel to provide a single continuous flat surface.
Preferably, the first material has a lower thermal conductivity than the second material. Further preferably, the second material has a higher compressive strength than the first material. The second material may be more dense than the first material.
Advantageously, the first insulating portion has a recess in its edge opposite the second insulating portion, arranged to receive an edge of an adjacent insulating panel.
This allows adjacent insulating portions to be more easily constructed and stay in position, and together provide a single continuous flat surface, Preferably, an edge of the first insulating portion comprises a recess in which an edge of the second insulating 20 portion is located.
Advantageously, a surface of the extended portion comprises one or more raised portions. In this case, the indentation should be correspondingly shaped to receive the raised portion(s), in particular so that the entrance to the indentation is smaller than the height of the extended portion at the raised portion(s), so that the extended portion "clicks" into place within the indentation.
The insulating panel may be formed of an insulating 30 polymer. The insulating polymer may be expanded polystyrene. The insulating panel may be profile cut from a block of expanded polystyrene or shape moulded. Alternatively, the insulating panel may be made of any material from the group of extruded polystyrene, polyurethane or polyisocyanurate. The material may have a thermal conductivity of 0.050W/mK or below. The material may have a thermal conductivity of 0.040W/mK or below. Preferably, the material has a thermal conductivity of 0.036W/mK or below. Advantageously, the material has a thermal conductivity of 0.031W/mK or below. The material may have a thermal conductivity of 0.021W/mK or below. It will be appreciated that other suitable insulating materials could be used.
In accordance with a second aspect of the invention there is provided a construction on a structural element of a building, comprising: a plurality of beams; a plurality of insulating panels as described above; wherein the first insulating portion of each insulating panel is positioned between first and second adjacent beams of the plurality of beams, and sits upon ledges extending from the first and second adjacent beams, and the second insulating portion of each insulating panel is positioned over the first adjacent beam. The first insulating portions of the insulating panels are positioned between adjacent beams of the plurality of beams, and the second insulating portions of the insulating panels are positioned over the beams.
It will of course be appreciated that features described in relation to one aspect of the present invention may be incorporated into other aspects of the present invention.
Description of the Drawings
Embodiments of the present invention will now be 10 described by way of example only with reference to the accompanying schematic drawings of which: Figures la to lb show example insulated panels; Figure 2 shows an example floor construction; Figure 3 shows a perspective view of an insulating edge barrier of the floor construction of Figure 2; Figures 4a and 4b show other example floor constructions; Figures 5a and 5b show insulated panels in accordance with embodiments of the invention; Figure 6 shows second insulating portions for an insulated panel in accordance with another embodiment of the invention; Figures 7a and 7b show insulated panels in accordance with other embodiments of the invention.
Detailed Description
Example insulating panels are now described with 30 reference to Figures la to lh.
Figure la shows a cross-section of an insulating panel 100. The first insulating panel 100 comprises a first insulating portion 1 of rectangular cross-section, with a recess la in a top edge, and a second insulating portion 5 located in the recess la. The first insulating portion 1 and second insulating portion 2 are glued together to form the first insulating panel 100. (In alternative embodiments the portions can be fixed together in other ways, as described in more detail later below.) The recess la and second insulating portion 5 are correspondingly sized so that the upper surface of the second insulating portion 5 is at the same level as the upper surface of the first insulating portion 1, so that the upper surface of the first insulating portion 1 and the upper surface of the second insulating portion 5 together provide a single flat surface. The first insulating portion 1 is formed of a low density insulating material with a low thermal conductivity, and the second insulating portion is formed of a higher density insulating material with a higher thermal conductivity than the first insulating portion, but also a higher compressive strength.
Figure lb shows an alternative insulating panel 101, comprising the first insulating portion 1, and an alternative second insulating portion 6 is located in the recess la. The material of the second insulating portion 6 is the same as the material of the second insulating portion 5. The horizontal cross-sectional length of the second insulating portion 6 is longer than the horizontal cross-sectional length of the second insulating portion 5, but they have the same vertical cross-sectional length so that again the upper surface of the second insulating portion 6 is at the same level as the upper surface of the first insulating portion 1.
Figures lc and ld show alternative insulating panels 102 and 103. Insulating panels 102 and 103 comprise a first insulating portion 2 of the same material as the first insulating portion 1, together with the second insulating portion 5 and second insulating portion E respectively. The first insulating portion 2 again has a recess 2a in which the second insulating portion 5 or 6 is located. In addition, the first insulating portion 2 has a second recess 2b on its other top edge.
Figures le and lf show other alternative insulating panels 104 and 105. Insulating panels 104 and 105 comprise a first insulating portion 3 of the same material as the first insulating portions 1 and 2, together with the second insulating portion 5 and second insulating portion 6 respectively. The first insulating portion 3 has a single recess 3a in which second insulating portion 5 or E is located. The horizontal cross-sectional length of the first insulating portion 3 is longer than the horizontal cross-sectional length of the first insulating portion 1.
Figures lg and lh show alternative insulating panels 106 and 107. Insulating panels 106 and 107 comprise a first insulating portion 4 of the same material as the first insulating portions 1, 2 and 3, together with the second insulating portion 5 and second insulating portion 6 respectively. The first insulating portion 4 has a recess 4a in which the second insulating portion 5 or 6 is located, and a second recess 4b on its other top edge. The -10 -horizontal cross-sectional length of the first insulating portion 4 is longer than the horizontal cross-sectional length of the first insulating portion 2.
An example floor construction is now described with reference to Figures 2 and 3. The floor construction 10 comprises a plurality of concrete beams 11a, fib with ledges extending from each bottom edge. A floor is formed of a concrete layer 12 upon an optional gas-impermeable membrane 13. A wall 15 is located at one edge of the floor construction 10, and an insulating edge barrier and screed rail 14 is positioned between the wall 15 and the floor layers 12 and 13. The insulating edge barrier and screed rail 14, shown in perspective view in Figure 3, is a panel of insulating material of rectangular cross-section, which can be reinforced to provide both an insulated edge to the floor after its construction, and a screed rail for use when laying the concrete later 12 during its construction.
A "starter" insulating panel 110 is positioned between the wall 15 and a first beam ha adjacent to the wall 15. The starter insulating panel 110 comprises only a single insulating portion similar to the first insulating portion 1 shown in Figures la and lb. The flat edge of the starter insulating panel 110, the edge without the recess la, is positioned against the wall 15. The bottom of the other edge of the starter insulating panel 110, the edge with the recess la, is positioned on the adjacent ledge of the first beam lla. As can be seen from Figure 2, the starter insulating panel 110 is dimensioned so that it fits exactly between the wall 15 and the first beam ha, the top of the starter insulating panel 110 is above the top of the first beam 11a, and its recess la is dimensioned so that the bottom of the recess la is at the same level as the top of the first beam ha.
An insulating panel 106a, of the kind shown in Figure lg (but oriented in the opposite horizontal direction), is positioned adjacent to the starter insulating panel 110. The first insulating portion 4 of the insulating panel 106a is positioned between the first beam 11a and a second beam llb adjacent to the first beam 11a. The second insulating portion 5 of the insulating panel 106a sits on the top of the first beam ha. The edge of the second insulating portion 5 opposite the first insulating portion 4 is located within the recess la of the starter insulating panel 110.
Again as can be seen from Figure 2, the second insulating portion 5 is dimensioned so that the top of the second insulating portion 5 is at the same level as the top of the starter insulating panel 110, as well as being at the same level as the top of the first insulating portion 4.
A further insulating panel 106b of the kind shown in Figure lg is positioned between the second beam llb and another beam (not shown in Figure 2). The bottom edges of the first insulating portion 4 of the insulating panel 106b sit upon the adjacent ledges of the second beam llb and other beam. The second insulating portion 5 of the insulating panel 106b sits upon the second beam 11b, and as can be seen from Figure 2 an edge of the second insulating panel 5 of the insulating panel 106b is located within the recess 4a of first insulating panel 4 of the insulating panel 106a.
-12 -Thus, it can be seen that the starter insulating panel 110 and insulating panels 106a and 106b together provide a complete insulated layer above the beams ha and 11b. The low thermal conductivity of the material of the first insulating portions 4 of the insulating panels 106a and 106b positioned between the beams provides a high level of insulation, while the high compressive strength of the material of the second insulating portions 5 of the insulating panels 106a and 106b positioned over the beams provides good load-bearing properties. However, as the first insulating portions 4 and second insulating portions 5 are provided as connected parts of a single insulating panel, construction using the insulating panels 106a and 106b is simple. Further, as each second insulating portion 5 sits in the recess of an adjacent insulating panel they are kept in place, making the insulated layer secure and easy to construct.
Example floor constructions incorporating differently dimensioned first insulating portions and second insulating portions, to take into account different locations of beams and walls, are now described with reference to Figures 4a and 4b.
Figure 4a shows a floor construction with an insulating panel 103 comprising first insulating portion 2 positioned between adjacent beams ha and llb which are more closely spaced, and an insulating panel 106 comprising a first insulating portion 4 positioned between adjacent beams llb and 11c which are less closely spaced. The insulating panels 103 and 106 further comprise second insulating -13 -portions 5 positioned over the beams 11b and 11c. (In other words, the insulating panels 103 and 106 are oriented as in Figures la to 1h.) Figure 4b shows a floor construction with an insulating panel 100 comprising a first insulating portion 1 positioned between a wall 15 and adjacent beam lid, and insulating panels 106 comprising first insulating portions 4 positioned between adjacent beams lld and lle, and between adjacent beams lie and llf. Second insulating portions 5 of the insulating panels 100 and 106 are positioned over the beams 11d, lie and llf.
It will be appreciated that insulating panels comprising other suitably dimensioned first and second insulating portions could be used depending on the locations of the walls/beams. For example, the insulating panels 101, 103, 105 and 107 comprising the second insulating portion 6 of longer horizontal cross-sectional length could be positioned over a plurality of very closely spaced adjacent beams. Further, insulating panels could be adapted during construction of the wall by cutting the first insulating portion to the appropriate size, for use in gaps between adjacent beams, or between a beam and a wall, of nonstandard width.
First and second insulated panels in accordance with embodiments of the invention are now described with reference to Figures 5a and 5b.
As shown in Figure 5a, as in the examples above an insulating panel 200 comprises a first insulating portion 20 30 with recesses 20a and 20b, and a second insulating portion -14 -located within those recesses. However, in this embodiment the recess 20a of the first insulating portion 20 has an indentation 20d, and the second insulating portion 25 has a corresponding extended portion 25a that fits within the indentation 20d. The end of the extended portion 25a is thicker, and the indentation 20d has a corresponding larger internal space, so that the extended portion 25a of the second insulating portion 25 is held in place within the indentation 20d of the first insulating portion 20.
Figure 5b shows a similar insulating portion 201 comprising a first insulating portion 21 of longer horizontal cross-sectional length than the first insulating portion 20, with recesses 21a and 21b, and indentation 21d in the recess 21a.
In this way, the first and second insulating portions of the insulating panels can be connected and fixed together quickly and easily, and for example do not need to be glued, which requires time for the glue to cure.
Figure 6 shows second insulating portions for insulated panels in accordance with another embodiment of the invention. The two second insulating portions 30 are cut from a single flat panel 31 of insulating material, for example a sheet of expanded polystyrene. As can be seen, the extended portions 30a of the second insulating Portions 30 are inversely shaped, so that by cutting one second insulating portion 30 from panel 31 the remaining part of the panel 30 necessarily forms the identical second insulating portion 30. In this way, the two second -15 -insulating portions 30 are constructed with no material of the panel 31 being wasted.
Figures 7a and 7b show insulated panels in accordance 5 with other embodiments of the invention.
Figure 7a shows an insulating panel 40 comprising a first insulating portion 41 and a second insulating portion 42. An extended portion on a side of the second insulating portion 42 fits within an indentation in a side of the first insulating portion 41. The upper surface of the extended portion of the second insulating portion 42 has a plurality of raised 'teeth" 42a, which fit into corresponding recesses in the upper inner surface of the indentation of the first insulating portion 41, provided a secure locking fit between the first insulating portion 41 and second insulating portion 42.
Figure 7b shows an insulating panel 50 comprising a first insulating portion 51 and a second insulating portion 52. An extended portion on a side of the second insulating portion 52 fits within an indentation in a side of the first insulating portion 51. In this case, the surfaces 53of the indentation and extended portion are flat, but nevertheless the first insulating portion 51 and second insulating portion 52 are held together by the friction between the surfaces 53. The indentation may be dimensioned to be slightly smaller than the extended portion, so the extended portion is compressed within the indentation, creating increased forces and so increased friction between the surfaces 53.
-16 -While the present invention has been described and illustrated with reference to particular embodiments, it will be appreciated by those of ordinary skill in the art that the invention lends itself to many different variations not specifically illustrated herein. The skilled person will in particular appreciate that the insulating panels could be shaped in various alternative ways while still being in accordance with the invention.
