Description

(54) CAVITY BARRIER INSULATION (71) We, CAPE INSULATION LIMITED, a British Company of 114 Park Street, London W1Y 4AB, England, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to cavity barrier insulation, and is especially concerned with the provision of a new material for use as thermal insulation and as a fire stop in cavities, for example above suspended ceilings or in ducts or in floor voids.
Hitherto material for this purpose has consisted of a blanket comprising fibrous insulating batt faced on both sides with scrim cloth and sewn through to give a blanket appearance. A recent suggestion for an alternative material is a laminate of asbestos cloth and a fibrous insulation batt. Regulations have recently been introduced by the relevant authority governing the properties of materials used as fire stops.
The aim of these regulations is to ensure that such materials either stop the spread of fire or reduce it to a level which enables any fire which breaks out in a building in which this material is used to be readily brought under control.
There is further a requirement that such a material should also have the property of resisting the penetration of smoke through it or at least permitting the penetration through it of only a small proportion of the smoke impinging upon it.
The fire stop materials used hitherto and referred to above either do not satisfy the new regulations or, because of the difficulties involved in fitting them, tend to be very expensive to provide and install. It is an object of the present invention to provide a new fire stop material which will meet these new regulations and which is relatively cheap to manufacture and install.
The new fire stop material of the present invention, in its simplest form, comprises a sandwich of two layers of heat-resistant fibrous material, each of which is substantially unbonded, and, between the said layers, an inorganic heat-resistant impermeable foil.
The layers of heat-resistant fibrous material, preferably inorganic material, suitably batts of such fibrous materials as mineral wools, e.g. rockwool, slag wool and glass wool, and also alumino-silicate ceramic fibres. A particularly suitable material is that sold under the trade mark "Rocksil". The fibrous batts are preferably unbonded, although very small amounts of organic binder may be present, if desired. It is preferable that they be completely unbonded, however, since any binder wifl normally tend to contribute to a fire.
The impermeable foil sandwiched between the two layers of fibrous material is suitably a metallic foil, and is preferably aluminium foil. Copper foil may also be used. Foils having a thickness of 0.01 to 0.1 mum., for example 0.025mm., are particularly useful. There may be some light bonding between the foil and the adjacent layers of fibrous material, but no real advantage is gained by this and again the binder may contribute to the fire which is un desirable. It will be appreciated that when we refer herein to "heat-resistant" materials we intend those materials, of which examples have been given above, which do not burn or melt below 500 "C.
The layers of fibrous material may be from 25mm.-l00mm. thick. Each layer may com prise a single batt or two or more batts super posed on one another.
Although the fire stop material may consist of a simple sandwich of two layers of fibrous material interleaved with the impermeable foil, it is preferable that the two outer faces of the material be surfaced. One or both surfaces may be provided with a wire mesh facing, but in a preferred embodiment one of the surfaces is faced with a wire mesh and the other surface has a facing of cloth which is so sized as to envelop the edges of the fibrous material batts and overlap the edges of the wire mesh on the opposite surface. Alternatively the edges of the cloth, which may suitably be scrim cloth, glass or asbestos cloth, and is preferably treated beforehand to render it flame retardant, may be tucked under the edges of the wire mesh.The entire assembly, consisting of wire mesh, heat insulating fibrous batt, impermeable foil, heat insulating fibrous batt and facing cloth, may then be sewn through to give it a quilted or blanket appearance.
In a further embodiment the fire stop material may comprise three layers of heatresistant fibrous material with an impermeable foil between each pair of adjacent layers.
The wire mesh facing, which is suitably used to give rigidity during the fixing of the material in place in a building, is suitably of a mesh size of 0.25" to 3" (e.g. 24 swg 1 x 1) and may be made of galvanised steel or, where cost is not so important, stainless steel. Expanded metal could also be used to surface the material.
The fire stop material of the invention may be made as follows. The required length of fibrous batt, of thickness equal to half that of the final blanket, is cut from a roll of batt and placed on a similar length of scrim cloth, the width of the scrim cloth being equivalent to the width of the batt plus twice the thickness of the final blanket plus approximately 12" (300 mm) to allow for overlap. Metal, e.g.
aluminium, foil of the same length and width as the batt is placed on the batt and a second length of batt, having the same dimensions as the first, is cut from the roll and placed on the foil.
The scrim is folded round the edges of the batts and foil and is folded again onto the outer surface of the second length of batt. A length of wire netting, having the same linear dimensions as the batt, is placed over the assembly, and a composite quilt or blanket is then formed by stitching through the thickness of the materials with wire. The distance between the rows of stitching may be the order of 6" (150mm), and care must of course be taken to ensure that at the edges the stitching passes through the scrim cloth overlap.
Preferably the material is made in continuous lengths, with, respectively, scrim cloth, batt, foil, batt and wire netting being drawn from respective sources of such and superposed one on another on a continuously moving belt upon which the material is also stitched and cut to conveniently handle able size.
The invention will now be further described with reference to the drawings accompanying the Provisional Specification, which are diagrammatic in nature and in which:- Figure 1 is a side elevation of a simple fire stop in accordance with the invention, with the component parts shown slightly apart for ease of understanding; Figure 2 is a similar view of a more complicated fire stop material; and Figure 3 is a plan view of the material shown in Figure 2.
Referring to Figure 1, the fire stop material comprises two fibrous batts 1 of insulating material such as "Rocksil" and suitably of 25 mm. thickness, sandwiched between which is an impermeable aluminium foil 2, suitably of a thickness of the order of 0.002" (0.05 mm).
The material of Figure 2 also comprises two layers of fibrous material 1 and an inter leaved layer of foil 2. However, in this case the fibrous material batts 1 are faced with an enveloping scrim cloth 3, which covers the edges of the batts 1 and also a marginal portion 4 of the upper batt. A wire mesh 5 is placed on top of the assembly and is stitched thereto by stitches 6 which penetrate the entire thick ness of the material to give it a quilted or blanket effect.
