BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the invention will now be described in relation to the following drawings in which: Figure 1 is a cross-section of a floor structure built in accordance with the first preferred embodiment of the invention; Figure 2 is a partial cut-away plan view of the insulating material of the present invention installed between a pair of joists; Figure 3 is a cross-structure of a floor structure which shows the use of a fire rated material; and Figure 4 shows how two layers of fire rated material may be installed. DESCRIPTION OF THE PREFERRED EMBODIMENT
Figure 1 illustrates a floor structure which formed using a method of insulating a floor and a insulation material of the first preferred embodiment.
The floor structure comprises a plurality of bearers which will usually be supported on stumps (not shown) inserted into the ground. The bearer 1 illustrated in Figure 1 is one of a plurality of bearers which all run in the same direction (see Figure 2) . Supported on these bearers 1 are a plurality of joists 2 which run perpendicularly to the bearers 1. In order to insulate the floor structure, an insulation material comprising a substrate in the form of a sheet of aluminium foil 5 and a plurality of insulation portions in the form of insulating batts 6 formed of fibre glass are overlaid on the joists such that they are supported by the joists 2 with the insulating batts 6 below the intended level of the flooring material 3. The aluminium foil is fastened to the joists, typically by staples using a staple gun. The flooring material may be wooden floor boards, composite board, particle board or the like.
As shown in Figure 2, the insulation material has a plurality of apertures 7 through the material which are spaced apart in order to correspond to the spacing of the joists 2. These apertures 7 provide attachment portions for allowing the flooring material 3 to be attached to the joists. That is the attachment portions permit attachment of the flooring and joists rather than acting to actively attach the substrate to the joists (the substrate can be separately attached to the joists by fasteners, if desired) . These apertures allow flooring 3 to be adhered to joists 2, thus preventing the floor from squeaking. Furthermore, the flooring 3 is also fastened to the joists 2 by fasteners such as nails.
It will thus be seen by referring to Figure 1 that the substrate 5 hangs below the top surface 4 in order to accommodate the insulating batts 6. Thus, persons skilled in the art will appreciate that the additional length of aluminium foil 5 between the attachment portions which overlie the joists and one side of the batt 6 corresponds substantially to the height of the insulating batts. Typically, the joist spacing is 450mm in which case the length of aluminium foil from attachment portion to attachment portion is about 620mm. Similarly, if the joist spacing . is 600mm the length of aluminium foil is about 770mm.
The insulation material of the preferred embodiment will usually be supplied as a roll of material. As the spacing of joists is standard, one end of the roll can be aligned and then, the material can be deployed rapidly by rolling it out. Persons skilled in the art will appreciate that there are a large number of alternative embodiments which fall within the scope of the invention.
For example, while the invention has been described in relation to a wooden structure for supporting flooring material, the invention is equally applicable to situations where the frame is metal.
Similarly, while the spaced attachment portions in the preferred embodiment are provided by a number of apertures, the attachment portions may be provided by many other type of perforations provided these allow adhesive to pass from one side of the material to another in order to allow the flooring to be adhered to the joists to prevent squeaking. Indeed, the substrate may be formed from a porous material or have porous portions where it is designed to be attached to the joists.
Further, while it is preferred that the substrate is a sheet of heat reflecting aluminium foil, it will appreciated that other substrates may be used while obtaining some or all of the benefits of the present invention. For example, other heat reflecting materials will clearly be suitable. Further, where the substrate is merely required to support the insulating material it need not be formed of a heat reflecting material. It could be for example, formed of plastic. In one particularly preferred embodiment, the substrate is formed of a fire rated material to thereby provide fire protection in addition to insulation. The substrate may also be a web, for example a lattice-like web of strips of material and function to support the insulating portions. Further, while it is preferred that the insulating portions are supported against gravity by the substrate or web, the insulating material can be supported by its attachment to the substrate or web and hang below the substrate or web in use. This is particularly suitable where the insulation material is to be installed between floors, as if the material becomes detached it will still be supported, for example by the ceiling.
In the preferred embodiment, the insulating portions are provided by fibre glass batts adhered to the aluminium foil. Persons skilled in the art will appreciate that other insulating materials may also be used - e.g. polyester batts or rockwool. The insulating material may alternatively or additionally be chosen to provide acoustic insulation.
Further, in embodiments where the invention is provided in the form of a insulation material, the insulating material must be attached to the substrate in order to allow for ready installation. However, where the invention is embodied as a floor structure or as a method, the insulating material could be provided separately and installed separately to the substrate. Although, it is preferred that it is provided with insulating material attached to the substrate.
Further, while the example of fasteners used to attach the substrate to the joists and the flooring to the joists are given above a person skilled in the art will appreciate the number of different fasteners can be used. For example, if a metal floor substrate is used, fasteners in the form of screws would be more appropriate than nails. Further, it may be possible to attach the substrate to the joist using an adhesive rather than staples depending on the embodiment.
In a further embodiment of the method of the invention, the substrate could be perforated after it has been installed in order to match to the joists spacing.
Persons skilled in the art will also appreciate that joists and bearers could run in different directions in different areas of the floor structure.
Referring to Figure 3 there is shown a second embodiment which relates to the second aspect of the invention. As discussed above, the substrate can be a fire rated material in order to provide fire protection to the structure. Figure 3 illustrates that in accordance with the second aspect of the invention a substrate 15 formed of a fire rated material may be conveniently installed in the building with the substrate otherwise constructed in accordance with the substrate of the first embodiment - that is by providing attachment portions where an adhesive can pass through the substrate 15 in order to allow the flooring 3 to be attached to the joists 2. The material can then be rapidly deployed in the construction of a structure by rolling it out over the joist with the attachment portions in register with the joists. The flooring material can then be deployed very quickly during construction of the structure.
Figure 4 shows an alternative embodiment where fire rated substrate 15 is located between a floor 3 and a ceiling material (not shown) where the floor 3 is between two different levels of a structure. The substrate 15 formed of fire rated material is attached to both the top and bottom of the deep floor joists of the floor structure to provide fire protection between the two levels of the building. There may also be provided a thermal or acoustic insulating material carried by one or both of the substrates . A person skilled in the art will appreciate that numerous other variations fall within the scope of the invention described herein. For example, where there is a danger of moisture build up on the substrate, drainage holes may be provided in the substrate to allow moisture to pass therethrough.
