Description

SPECIFICATION Improvements in or relating to thermal insulation Description of invention This invention relates to strip thermal insulation adapted for quick installation. The insulation is T-shaped to fit betweem parallel support members.
According to one aspect of this invention there is to provide a generally shaped rollable and unrollable thermal isulation unit comprising; a solid strip or batt having a T-shaped cross section extending from one end to the other end of said batt including a T cross bar and a T cross bar support; said T cross bar and said T cross bar support each being continuous, uniform and solid in cross section throughout their length; said T cross bar including side, upper, lower and end surfaces; said T cross bar support including side, end and lower surfaces; a U-shaped vapour barrier attached to said batt and covering said T cross bar lower surface only and covering said T cross bar support lower and side surfaces; said vapour barrier having an end portion extending beyond at least one end of said batt a distance from about 1 1/4 to 1 1/2 times the height of said batt; said vapour barrier end portion being foldable upwardly against at least one end of said batt including said one end T cross bar and T cross bar support end surfaces to extend above said upper surface of said T cross bar; and said T cross bar support being in vertical height greater than the height of said T cross bar by from about two to four times.
Preferably said vapour barrier includes a second end extending beyond said other end of said batt a distance from about 1 1 4 to 1 1 2 times the height of said batt; and said second end of said vapour barrier is foldable upwardly against said other end of said batt including said other end T cross bar and T cross bar support end surfaces, to extend above said upper surface of said T cross bar.
Conveniently said batt T cross bar and T cross bar support are individually generally rectangular members bonded together.
According to another aspect of this invention there is provided a plurality of interconnected generally rectangular shaped rollable and unrollable thermal insulating units comprising: at least two solid abutting strips or batts each having a T-shaped cross section extending from one end to the other end of each batt including a T cross bar and a T cross bar support; each of said T cross bars and said T cross bar supports being continuous, uniform and solid in cross section throughout their length; each of said T cross bars including side, upper, lower and end surfaces; each of said T cross bar supports including side, end and lower surfaces; a U-shaped vapour barrier attached to each of said batts and each covering its respective T cross bar lower surface only and covering its respective T cross bar support lower and side surfaces; each of said vapour barriers having an end portion extending beyond at least one end of its respective batts a distance from about 1 1/4 to 1 1/2 times the height of its respective batt; and each of said vapour barrier end portions being folded upwardly against at least one end of its respective batt including its respective one end T cross bar and T cross bar support surfaces, and each extending above its respective upper surface of its respective T cross bar; said upwardly folded end portions of said vapour barriers of said at least two abutting batts being in abutting relation and secured to each other; and said cross bar support in vertical height greater than the height of said T cross bar by about two to four times.
The features if this invention result in a batt of insulation which is both inexpensive and simple to install. The batt can be installed simply by unrolling the insulation on top of a support structure and can be secured by attaching a covering panel. Thus the invention is particularly adapted for but not limited to use in roofs of prefabricated metal buildings. The T-shaped batt can be constructed inexpensively in a one ortwo piece form. Moreover, if a roll of insulation should run out before the void between the parallel structural members is filled means are provided for joining consecutive batts of insulation while maintaining a water impervious barrier.
Consecutive batts are connected by folding adjacent vapour barrier extensions upwardly, and connecting these extensions in any suitable manner.
The T-shaped batts are formed either by notching out the edges of the batt using a high speed saw or by attaching a wider piece of insulation on top of a narrower one. The batts of insulation fit substantially between parallel support members; however the narrow horizontal flanges of adjacent T-shaped batts may overlap on top of the support members and may be retained by a covering panel.
In order that this invention may be more readily understood and so that further features thereof may be appreciated the invention will now be described by way of example with reference to the accompanying drawings in which, Figure 1 shows a perspective view of one end of a batt of insulation in accordance with the invention showing the extension of the vapour barrier beyond the end of the batt, Figures 2 and 3 show cross-sectional views of respectively one and two piece batts of insulation in accordance with the invention, Figure 4 shows how two strips of insulation in accordance with the invention can be connected in an end-to-end fashion and Figure 5 shows a cross-sectional view of the T-shaped insulation in accordance with the invention installed in a roof structure.
A T-shaped batt of insulation is shown in Figure 1.
The strip or batt is of generally rectangular form and can be rolled into a roll or reel and unrolled therefrom. The strip consists of a continuous uniform, solid T-shaped member of thermal insulating material 10 extending from one end of the batt to the other and a U-shaped vapour barrier 12. As shown in Figure 2 the vapour barrier 12 contacts only the lower surfaces 14, 16, 18, 20 and 22 of the T-shaped batt A, and extends beyond at least one end of batt A.
The vapour barrier 12 may be made of sheet vinyl material, foil-reinforced kraft, vinyl-reinforced foil, vinyl reinforced polyester or any other material that is substantially impervious to water vapour. The barrier 12 may be applied to the insulating material 10 with a suitable adhesive using conventional lamination equipment.
The member 10 of insulating material can be made in either one or two pieces as shown respectively in Figures 1 and 2 or Figure 3.
A solid one piece member 10 is shown in Figures 1 and 2. It is made by cutting out the lower corners of a rectangular sectioned member that is indicated is dashed lines, to form notch 24 having walls 14 and 16, notch 26 having walls 20 and 22, and also to form flanges 28 and 30. The cutting can be done with a high speed saw. The precise size of the notches 24 and 26 and their geometry is at the discretion of the person performing the invention. Figure 2 shows that the vertical height of the notches 24 and 26 is substantially greater than the height of the resultant flange sections 28 and 30. Moreover specifically, the notch height is from about two to four times the height of the flange. The flange could have a height of approximately 5 cms (two inches).
The two piece member B shown in Figure 3 is made by connecting two strips of thermal insulation 32 and 34. The top strip 32 which is wider than the base strip 34 is attached in any suitable manner and preferably is glued to the base strip.
Consecutive batts may be connected together in the manner indicated in Figure 4. As shown in Figure 1, each batt's vapour barrier 12 extends beyond each longitudinal end of the batt 10. As shown in Figure 4 the vapour barrier extension sections 40 and 42 are folded upwardly flush against the end of its respective batt C or D. The extension 40 shown in Figure 1 is long enough to provide a crest 44 or 46 above the upper surface of the batt which is about 1 4 to 1 2 of the height of the batt. Thus the extension is about 5 cms (two inches) long. Thus it is to be appreciated that the length of the extension 40 is from 1 1 4 to 1 1;2 times the heightofthe batt 10.The adjacent upstanding vapour barrier extension sections 40 and 42 are then spliced together by folding and stapling the protruding crests 44 and 46 together or by heat sealing them is a plastics material vapour barrier is used, or by any other suitable means.
One method of installing the insulation is illustrated in Figure 5 which shows a roof structure having parallel Z-shaped purlins 50, roof panel 52, fasteners 54 and insulation batts E, F, G and H. The batts of insulation, which are initially supplied in rolls, are unrolled so that the vertical or stem portion 58 of each batt fits into the void between the purlins 50 while the horizontal flange portions 60 and 62 rest atop the purlins. If a roll runs out before the entire length of the channel between the purlins is filled, a new batt can be spliced to the old as described above and as illustrated in Figure 4.
Adjacent parallel batts such as batts F and H adjacent to batt G are laid to insure that the horizontal flange portions 60 and 64, and 62 and 70 overlap. Thus each flange must have a width greater than half the width of the purlin 50. Figure 5 shows an arrangement wherein every other batt such as batt E and G are laid first and intermediate batts such batts F and H are laid so as to overlap the first laid batts. However, other arrangements could be used including laying batts a row at a time so that one horizontal flange portion on each batt would be atop the adjacent batt and the other flange portion would be below the other adjacent batt.
The insulation shown in Figure 5 is secured and compressed into the voids between purlins by laying roof panel 52 on top of the purlins and overlapping horizontal flange portions. The roof panel can then be secured to the purlins by fasteners 54. In this way the horizontal flange portion serve as a barrier to heat transfer by conduction between the roof panel and the purlins.
While this invention has been described as having a preferred design, it will be understood that it is capable of further modification. This application, is therefore, intended to cover any variations, uses, or adaptions of the invention following the general principles thereof and including such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains, and as may be applied to the essential features hereinbefore set forth and fall within the scope of this invention or the limits of the
