"INSULATING UNITS-FOR BlUILDINGS"

The following statement is a full description of the invention including the bes 't method of perfrTing it known to us:

~;~is~j~iP~

THIS INVENTION relates to insulating units f.or buildings. Ie Thermal insulation of the ceilings, walls and floors of buildings is commonly effected in a variety of ways, notably by the use of reinforced paper with aluminium foil adhered to one or both faces, or, of aluminium foil, or of batts of fibreglaso, expanded polystyrene or the like, made for installation above the ceilings, or granular insulating material introduced into wall cavities. 00 B 0 0 The object of the present invention to 000q 0

provide insulating units which are particularly dimple and economical to make and to instal, and highly effect- 09 0 ive in use. 00b 0 0'0 15 With the foregoing and other objects in view, the invention resides broadly in an insulating unit including a substantially rectangular, and preferably 000 transversably corrugated tray comprising a section of aluminium foil or other reflective sheet 'material with

00 40 20 integral ide flanges the edge portions of which are bent 04 00 outwardly to form substantially co-planar supporting 4a flanges capable of being supported by or attached to joists, studs or otr parallel structural members of a building. Preferably the main central part of the unit 4$ 01 is formed with parallel weakened or bend fines inset from 04 0 0 0 0 00 the side flanges to facilitate bending along these lines to reduce, where necessary, the effective width of the unit. The end portions of the unit may also be bent in the same general ditect on as the side flanges, and for under-floor insulation the units may be formed with perforations for the drainage of condensed moisture. Other features of the invention will become apparent from the following description. In order that a preferred embodiment of the invention may be readily understood and car ed into practical effect, reference is now made t ahe accomp- anying drawings, wherein: FIG. 1 is a perspective view of an arrangement of insulating units according to the invention applied to ceiling'~ joists of a bulding; FIG. 2 is a sectional view of part of a ceiling structure to which the insulating units are applied; FIGS. 3 and 4 are sectional views of a part of a ceiling,structure to which insulating units are applied ft 0* in different ways; 0 ft.+o FIG. 5 is a sectional view of part of a floor stnucture with units according to the invention applied ft 0 f 00* beneath the floor; and 00 0 ft 0 15 FIG. 6 is a sectional view to large scale ft ft showing the corrugated configuration used in the insul- ft oP ating units. ft 0oft0 f The insulating units 10 shown in various applications in the drawings, are in the form of trays ft *0 ft 0 20 made of corrugated .aluminium foil of the known polished Oft ft ft 00 'type having the qualities of very high thermal reflection- 00 0 0a oft and low thermal emissivity, together with a fair degree of toughness and resilience. It should be understood, how- ft Of 9 #0 t 09 f ever, that other sheet material having these qualities may be used. ft 0+ 00 The foil is corrugated, as shown in the enlarged sectional View of FIG. 6. It has been found that corrug- ating the foil by the use of interacting corrugated metal rollers is likely to be=Yry unsatisfactory, resulting in inadequate depth of corrugation and/or spilling of the foil. However, very satsfactory results have been achieved by the use of i beracting rollers with meshing corrugations of a resilietitly deformable material. The rollers may be metal cylinders of, say, 120mm to 14imm diameter faced with fairly deeply corrugated rubber or the like, one of the rollers being driven, and adjust- ment means being provided for moving either of them in parallelism to vary the pressure, or-the clearance, ;ement between the two. This apparatus has been found effect- ed 5 ive in corrugating the sheet material, or several super- imposed sections of the sheet material simultaneously. eiling The side portions of the transversely corrugated rectangular foil sections 10 are bent obliquely upwards .rt of to'Torm side flanges 11, and the edge, portions of these plied 10 side flanges are bent outwardly to form substantially *i a a 6 co-planar support.flanges 12. In addition, bend lines .9 9.9 6>0~ 9 '969, 'loor 13 are formed in the main central part of. each unit 9O 99 .ied inset some distance from and parallel to the side flanges n 94

9. 9 metal variations in the normal spacing of the joists. may be rng in taken up by varying the angles of the side flanges 11 to he 30 the central parts of the trays, but in the case of a more (i \-j ii significant reduction in the joist spacing then, as iing shown in FIG. 2, a row of the trays, as indicated The may be bent along the behd lines 13 to reduce the effect- ive width of the trays; or a row of the trays, as indicated orm or 35 at 10b, may be inverted to bridge the space between closely spaced joists. Instead of the trays 10 being seated between thi joists 15, they may be disposed transversely of the joists. As shown in FIG. 3, the trays 10 of alternate rows may be inverted to form an all-over insulating assembly; or, as shown in FIG. 3, all the trays 10 may be inverted, the support flanges 12 at one side of each row overlying the support flanges 12 at the near side of the succeeding row. As shown in FIG. 5, the tray units 10 may be qo used for thermal insulation below a floor 16 which is fixed to the floor joists 17 after the insulating trays *a 0 40 have been installed, their support flanges 12 resting 00t *0r 0 #0 on the floor joists. These Uh'de-floor trays are prefer- 0*4 4ra 15 ably formed with perforations (not shown) for the escape of any moisture, and the end units of each row should normally have their ends bent upwardly and fixed in usual manner. Insulating units according to the invention 1, are applicable also to the thermal insulation of timber- 0d 40 40 *0 framed walls, being stapled or otherwise secured to the studs, plates and/or nogging and in this and other applications the units may serve as a vapour barrier 0 particularly if adequately sealed in any appropriate manner at their edges. 0* 0 00 The insulating trays are normally installed, 40 0 00 *0 as shown in the various applications illustrated, so that there is an air gap between the reflective insul- ating surfaces and the ceilings, floors or other areas to which they are applied. This air gap itself serves as a valuable thermal insulation. A further advantage, particularly in install- ations such as illustrated in FIGS. 1 and 5, is that the tray-like units 10 may be used to receive loose insulat- ion material of any suitable type. Alternatively, if

.1 5" i desired, the trays may have insulating material adhesively applied to either their upper or lower surfaces, or to both. In certain applications it may be desired bthat the ends, as well as the sides, of the trays. should bent upwardly so the units are of shallw box-like form., the. foil being folded at the corners. In a modification of the invention, the trans- versely corrugated foil is supplied in a continuous roll within a container from which it may be withdrawn through S. formiig dies which impart the bends defining the side and support flanges, any suita..e means being used to sever insulating tray units of required length. The corrugation of the foil greatly increases 15 the reflective area of the units and imparts a measure of additional rigidity. The units are readily handled, laid and fixed and', when laid as shown in FIGS. 1 and 2, clearly indicate the location of the ceiling joists which may be walked without risk of damage to the units or to 20 the ceiling. The units will be found to be highly efficient S• in thermal insulation and in the foregoing and other respects to be very. effective in achieving the objects S for which they have been, devised. It will, of course, be understood that the particular embodiment of the invention herein described and illustrated may be subject t'o many modifications of constructional detail and design, which will be readily apparent to persons skilled in the art, without departing from the scope and ambit of the invention.
