Preferably the channel is formed from a flat sheet having a number of fold lines 17, 19, 21, 23 cut into the material which are subsequently bent to form the member. The width of the block may be greater than the width of the back plate. The sheet may be made from extruded polypropylene and the insulating material may be EPS, PIR or phenolic insulating material. The invention is used to surround vents and act as a sleeve or jacket cladding the vent without requiring cutting out a channel in a block of insulating material.
Description
"An insulating member"
Introduction
This invention relates to an insulating member for insulating around a flooring periscope vent.
The use of suspended beam and block floor systems calls for the provision of underfloor ventilation. The underfloor ventilation is provided by way of periscope vents. The periscope vents are typically provided on two opposite sides of the structure and allow air to circulate underneath the floor and allow the release of gases from underneath the floor.
It is desirable to maintain the thermal value at the wall floor junction by maintaining the insulation continuity around these periscope vents, however in practice this is often not achieved. In order to insulate around the periscope vents, a channel must be gouged out of block-type insulating material to accommodate the periscope vent or a different type of flexible insulating material must be used to pack insulation behind the periscope vent intermediate the periscope vent and the inner leaf of brickwork. However, it is time consuming and relatively difficult to gouge an appropriately-dimensioned channel out of existing block-type insulation and often a different type of insulating material is not to hand. Accordingly, the areas surrounding the periscope vents are often left without insulation.
It is an object of the present invention to provide an insulating member that overcomes at least some of the above-mentioned problems.
Statements of Invention
According to the invention there is provided an insulating member for insulating around a periscope duct comprising: an elongate hat channel, which, in use, is vertically oriented, the hat channel consisting of an elongate back plate, a pair of side walls extending forwardly from the back plate, each of the side walls having a laterally, outwardly depending flange formed along its length, the insulating member comprising a substantially cuboid block of insulating material mounted on a rearwardly facing surface of the back plate and extending rearwardly from the back plate.
By having such an insulating member, it will be possible to provide insulation around the periscope vent in a simple and straightforward manner, thereby substantially maintaining the thermal value at the wall floor junction. The time required to install the insulation around the periscope vent is significantly reduced and it will not be necessary to use a different type of insulation material for this purpose.
In one embodiment of the invention there is provided an insulating member in which the hat channel is constructed from a substantially flat sheet of material having four fold lines extending along it's length about which the sheet may be bent into the hat channel shape. By providing a sheet of material with fold lines, the insulating member may be manufactured, packaged and transported in a compact manner and the sheet of material can be easily manipulated into a hat channel configuration on site by the individual installing the insulation.
In one embodiment of the invention there is provided an insulating member in which there is provided an additional pair of fold lines extending along the length of the sheet to provide side walls of different depths and flanges of different widths. This is seen as a particularly advantageous aspect of the present invention. By providing the extra fold lines, the insulating member may be used to insulate periscope vent cavities of different depths and widths.
In one embodiment of the invention there is provided an insulating member in which there are provided a plurality of additional pairs of fold lines extending along the length of the sheet to provide side walls of a plurality of different depths and flanges of a plurality of different widths.
In one embodiment of the invention there is provided an insulating member in which the fold lines are each formed by a cut made into the sheet of material.
In one embodiment of the nventiori there is provided an insulating member n which there are a pair of cuts made on one side of the sheet of material and at least two cuts made on the opposite side of the sheet of material.
In one embodiment of the invention there is provided an insulating member in which the width of the block of insulating material is greater than the width of the back plate. In this way, the block of insulathig member may be push fit into a cavity without deforming or damaging the hat channel material.
In one embodiment of the invention there is provided an insulating member in which the hat channel is constructed from extruded polypropylene and the insulating material is one of EPSI PIR or Phenolic insulating material.
Detailed Description of the Invention
The invention will now be more clearly understood from the following description of some embodiments thereof given by way of example only with reference to the accompanying drawings, in which:-Figure 1 is an isometric view of an insulating member according to the invention; Figure 2 is a front elevation view of the insulating member; Figure 3 is a plan view of the insulating member; Figure 4 is an isometric view of an alternative construction of insulating member according to the invention; Figure 5 is a plan view of the insulating member fitted between a pair of block insulation components without a periscope vent in place; Figure 6 is a front elevation view of the insulating member and block insulation components of Figure 6; and Figure 7 is a side cross-sectional view of a flooring periscope vent installed with the insulating member according to the invention in use.
Referring to Figures 1 to 3 inclusive, there is shown an insulating member, indicated generaHy by the reference numeral 1, comprising an elongate hat channel 3 and a block of insulating material 5 mounted on and extending rearwardly from the hat channel 3.
The hat channel 3 when in use is vertically oriented and comprises an elongate back plate 7, a pair of side walls 9, 11 and a pair of flanges 13, 15. The pair of side walls 9, 11 extend forwardly from the back plate 7 and each of the side walls 9, 11 has a flange extending along its length and depending laterally outwardly therefrom.
The elongate hat channel 3 is constructed from a sheet of material, preferably extruded polypropylene, and there are provided a plurality of fold lines 17, 19, 21, 23 formed by cuts in the sheet of material. In this way, the sheet of material may be bent around the fold lines 17, 19,21 and 23 to form the hat shaped channel just prior to installation. Two of the fold lines 17, 19 are on the rearwardly facing surface of the sheet of material and provide elbow joints beMeen the back plate 7 and the side walls 9, 11 respectively. The other two fold lines 21, 23 are on the forwardly facing surface of the sheet of material and provide wrist joints between the side walls 9, 11 and the pair of flanges 13, 15 respectively.
Referring to Figure 4, there is shown an isometric view of an alternative construction of insulating member, indicated generally by the reference numeral 41. The insulating member 41 comprises a plurality of additional fold lines 43, 45, 47, 49 formed by cuts on the forwardly facing surface of the sheet of material. By providing the fold lines 43, 45, 47 and 49 in addition to the fold lines 21, 23, the depth, D, of the hat channel and the width, W, of the flanges can be chosen accordingly by bending the sheet of material around one of the pairs of fold lines to suit the depth and width of the cavity into which the insulating member is being inserted.
For example, if the cavity into which the insulating member is to be inserted is relatively deep or narrow, the sheet of material may be bent around the pair of fold lines 45, 49, as illustrated in Figure 4. This will result in a hat channel 41 and side walls 9, 11 having a depth, D3, and a pair of flanges 13, 15 having a width, W. If on the other hand the cavity into which the insulating member is to be inserted is relatively shallow or wide, the sheet of material forming the hat channel may be bent around the pair of fold lines 21, 23. This will result in a hat channel and side walls 9, 11 having a shallower depth, Dl, and a pair of flanges 13, 15 having a greater width equal to [W + (D3-D1)]. If the cavity has a depth intermediate the deep and shallow cavities described above, the sheet of material may be bent around the pair of fold lines 43, 47 resulting in a hat channel and side wall 9, 11 with a depth D2 and a pair of flanges with a width equal to [W + (D3-D2)).
In the embodiment shown in Figure 4, there are three pairs of cut lines however it will be understood that more or less pairs of cut lines could be provided if desired to accommodate more or less depths and widths of cavity into which the insulating member may be inserted.
Referring now to Figures 5 and 6, there are shown various views of an insulating member 1, 41 mounted in a cavity. The periscope vent and the inner and outer leaves of bricks have been removed for clarity. The insulating member 1, 41 is mounted in a cavity formed intermediate two block insulation components 51. 53. The substantially cuboid block of insulation material 5 is preferably push-fit between the two blocks of insulation components 51, 53. The back plate 7 and the side walls 9, 11 define a channel 55 in the insulating layer for reception of a periscope vent (not shown). Each of the two flanges 13, 15 lies against the forwardly facing surface of the block insulation component 51, 53 adjacent thereto and preferably are taped in place with an insulation tape extending along the length of the free edge 57, 59 of the flange.
Referring now to Figure 7, there is shown a side cross-sectional view of a flooring periscope vent installed with the insulating member in position. The periscope vent, indicated by the numeral 71, provides an air passageway 73 from the exterior 75 of the building to a cavity underneath the floor 77. The periscope vent extends through the outer leaf of brickwork 79, through the insulation layer 81 and through the inner leaf of brickwork 83. The insulating member 1, 41 according to the invention is placed with the block of insulating material 5 intermediate the periscope vent 71 and the inner leaf of brickwork 83 and the side walls (not shown) of the insulating member 1, 41 extend forwardly from the back plate either side of the periscope vent.
In the embodiments shown the block of insulating material is preferably one of EPS, FIR or Phenolic insulating material. Preferably the block is cuboid in shape however other shapes may be envisaged. Furthermore, the block of insulating material may be provided with one or more elongate cuts along its length to provide a degree of compressibility to the block and allow it to be inserted between two adjacent blocks of insulation components.
Throughout this specification, the insulating member according to the invention has been described for use with a flooring periscope vent and it has particular advantages in such an application. It will be understood however that the invention is not limited solely to use with flooring periscope vents and could also be used to good effect with other periscope vents or ducts. For example, the present invention could be used with periscope ducts such as those provided for routing of services including, but not limited to, water piping, electrical services cabling or other such utility piping, ducting or cabling which extends through a wall of a dwelling or other building or structure.
In this specification the terms "comprise, comprises, comprised and comprising' and the terms "include, includes, included and including" are all deemed totally interchangeable and should be afforded the widest possible interpretationS The invention is in no way limited to the embodiments hereinbefore described but may be varied in both construction and detail within the scope of the claims,
