Definitions

  • the present invention relates to insulation in building walls and, especially in partition walls.
  • Such walls generally comprise panels, which define the outer surfaces of the wall, held together by fixing elements, often in the form of C-profiles, U-profiles, I-profiles or H-profiles. Between the panels, mineral fibre panels are positioned as thermal and, predominantly, sound insulation. Whilst these insulation elements provide good insulation for the majority of the area of the wall, the fixing elements provide a thermal and/or sound bridge from one side of the wall to the other, which is detrimental to the overall insulation properties. This is particularly a problem, because the fixing elements are often formed of metal. Although metal fixing elements provide a strong structure for the wall, they are also relatively thermally and acoustically conductive.
  • U-profile is a fixing element with a back-plate and two side plates extending perpendicularly from either end of the back plate and in the same direction as each other. There is a gap between the U-profile and one gypsum plasterboard. Insulation material is placed both between the U-profiles and in the part between the outside surfaces of the U-profiles and the gypsum plasterboards.
  • the insulation material is preferably a mineral fibre batt and the mineral fibre between the plasterboard and the U-profile may have a higher density.
  • EP0849420 describes a cassette wall with Z-profiles in which, the insulation panels extend beyond the flanges of the metal cassettes, separating the flanges from outer cladding. In this way, the thermal bridge is substantially reduced.
  • This document does not address thermal or acoustic bridging in partition walls and the system described has a number of disadvantages. Problems arise when fixing the cladding to the cassette, because of the distance between these two elements and the compressibility of the mineral fibre panel. This distance results firstly in the screws being subjected to bending stress. Secondly, since the mineral fibre panel is compressible, there is a problem that it may be more compressed in the region of the screw. This might create an uneven outer surface and compromise the structural soundness of the cladding.
  • the solution suggested in EP0849420 is to provide a firm outer layer in order to spread the pressure of the screw.
  • this firm outer layer further increases the distance that the screw must span between the cladding and the cassette. This may put more stress upon the screw itself, whilst also increasing the space that the building envelope occupies. Furthermore, the firm layer may further increase cost and might not contribute significantly to the insulation.
  • EP1179645 describes another attempt to diminish the thermal bridging in a cassette wall. Again, insulation material is disposed between the cladding and the flanges of the cassettes. In order to prevent the insulation in this space from being compressed, spacer elements are provided to give a fixed space between cassette and cladding in which the insulation material can sit.
  • the spacer elements may be in the form of a screw, having two separated threads with different diameters.
  • EP801190 describes an insulated metal wall construction.
  • the wall is a cassette wall and comprises a material strip manufactured from insulating material and dimensioned to absorb pressure forces. This document provides no information with regard to what material should be used for the material strip in order to provide the insulating and pressure absorbing properties. It also relates specifically to cassette walls rather than partition walls.
  • WO2004/001154 describes a profiled element for a building wall, especially a cassette wall, with a heat or sound insulation member arranged in the profiled element.
  • the insulation member is preferably made from mineral fibres and consists of at least two interconnecting insulation elements, the first of which fills the profiled element and the second of which is located on a large surface of the first.
  • the insulation member can cover flanges of the profiled element, thereby reducing the number of cold bridges. Since the insulation covers the flanges and due to the nature of the insulation, it is necessary when using such a profiled element to somehow provide a fixed gap between the panel and the element.
  • An object of the present invention is to provide a building wall, preferably a partition wall, which reduces the transmission of sound and/or heat through the wall and in particular through the fixing element that fixes the panels forming the surfaces of the wall together.
  • a further object is to achieve such a reduction without the need for any special form of fixing means to fix the panels to the fixing element and to provide a building wall which has a good structural strength.
  • the wall a first panel (3) and a second panel (4) defining the surfaces of the wall
  • the present invention also provides a method for reducing thermal or sound transfer through a wall comprising in any suitable order the steps of:
  • the present inventors have found a solution to these problems using dried gel products, commonly known as aerogels. These products are known to have excellent insulation properties, owing to their very high surface areas, high porosity and relatively large pore volume. In many cases, they are also highly fire resistant. They are manufactured by gelling a flowable sol-gel solution and then removing the liquid from the gel in a manner that does not destroy the pores of the gel.
  • gels are described as compositions, wherein a continuous liquid phase is enclosed by a continuous solid three-dimensional network of colloidal particles.
  • An aerogel can be formed by removing the liquid from the gel and replacing it with air as the dispersion medium.
  • Aerogel when used in the broader sense means a gel with air as the dispersion medium. Within that broad description, however, exist three types of aerogel, which are classified according to the conditions under which they have been dried.
  • aerogels also encompass dried gel products, which have been dried in a freeze-drying process. These products are generally called cryogels.
  • aerogel in its broader sense of “gel having air as the dispersion medium” encompasses each of aerogels in the narrower sense, xerogels and cryogels.
  • aerogel denotes aerogels in the broader sense of a gel having air as the dispersion medium.
  • aerogel compositions include both inorganic and organic aerogels.
  • the inorganic aerogels are often based on metal oxides such as silica, carbides and alumina, whereas organic aerogels include carbon aerogel and polymeric aerogels, for instance polyamide aerogels.
  • the solution of the present invention uses, more particularly, products including aerogel insulation in the form of a mat.
  • products including aerogel insulation in the form of a mat.
  • AMC aerogel matrix composite
  • These mats are commercially available from Aspen Aerogels, Inc. and are made by impregnating a matrix of re-enforcing fibres with a flowable sol-gel solution, gelling and then removing the liquid from the gel in a manner that does not destroy the pores of the aerogel.
  • aerogel matrix composites are mechanically strong, good insulators and require a shorter processing time than pure aerogels. They are, therefore, suitable for industrial use as insulating material and are commonly used for this purpose.
  • US 2002/0094426 describes aerogel matrix composites and their use for insulation purposes.
  • aerogel mats have been formed in different ways.
  • US 6485805 describes an insulating composite comprising silica aerogel granules and having a thermally reflective layer, which is preferably a thin aluminium foil layer.
  • the aerogel granules are preferably adhered to the thermally reflective layer with a binder.
  • aerogel particles into a composite material comprising fibres.
  • US 6479416 relates to a composite material comprising aerogel particles and thermoplastic fibres.
  • the composite may also contain other types of fibres, but the thermoplastic fibres bind to each other and to the granules of aerogel to form a cohesive composite material.
  • WO2006/065904 describes a method for making an insulation blanket comprising adding a wetting agent to aerogel particles before combining them in water with fibres to form a slurry. The slurry is then dewatered, and the resulting web dried and calendared to form the blanket. The method may also include providing a layer on at least one side of the blanket to form a panel. This document further describes a product, wherein the blanket is placed between at least two glass layers. The resulting panel may be used as a window, wall, floor or the like.
  • WO 98/32709 describes a material comprising an aerogel layer with binder and at least one further layer.
  • Aerogel mats are advertised for use in building applications by A. Proctor Group Ltd under the brand Spacetherm. These mats are AMC mats.
  • a "Spacetherm-CBS Overview" on the Spacetherm website suggests applying Spacetherm to structural elements including steel frames. Partition walls using metal fixing elements are not discussed so problems relating to the fixing of panels to the fixing elements and the compressibility of the mats are not addressed.
  • the present inventors have found that by providing, between the first side surface of the fixing element and the first panel, a mat comprising 20 to 95 weight % aerogel and having a compressive stress at 10% compression of at least 20 kPa or, if 10% compression is not reached before the maximum compressive stress, having a compressive strength of at least 20 kPa, it is possible to provide improved insulation in a wall with good structural strength and without the need to use special screws or spacers to create a fixed space between the fixing element and the first panel. Since the mat is capable of resisting a relatively high pressure, the mat used in the present invention effectively provides its own gap between the first side surface and the first panel.

  • the mat preferably comprises no more than 90, more preferably no more than 80 and most preferably no more than 70 wt % aerogel.
  • the stated weight % of aerogel denotes the content of aerogel in its "pure” form, e.g. without the inclusion of any content of binder, fibre or filler, if available in the mat.
