Definitions

  • the present invention relates to systems for a building envelope, such as walls or roofs, and in particular to those which are constructed using cassettes, which are usually metal and most usually steel cassettes.
  • the cassettes are fixed onto a substructure and insulation material is positioned in the cassettes. Cladding is then fixed to the outside of the cassettes.
  • Such constructions are particularly common in industrial buildings.
  • the steel cassettes are formed of a major plate, which is typically vertical and horizontal plates extending in the same direction from the upper and lower ends of the major plate. These horizontal plates connect at their opposite ends to downwardly directed flanges.
  • the wall may, therefore, be constructed using a number of these cassettes positioned one on top of the other such that the lower horizontal plate of an upper cassette faces the upper horizontal plate of a lower cassette.
  • the downwardly directed flanges of the cassettes overlap each other.
  • insulation material between the upper and lower horizontal plates of each cassette.
  • the insulation material can be held in place by the overlapping flanges and is usually in the form of a man-made vitreous fibre batt. This type of insulation material is particularly suitable for this application due to its good insulation properties, fire resistance and ease of installation.
  • the cladding is then fixed to the cassettes.
  • the cladding is typically metal cladding and is often fixed to the cassettes with screws that pass through the cladding and both overlapping flanges.
  • the transfer of sound from one cassette to another has clear disadvantages in that it may facilitate the transfer of sound from one part of the building, which may be used, for example, as a workshop and another part of the building, which may contain office space.
  • EP1179645 describes another attempt to diminish the thermal bridging in this type of 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. Again, this solution relates to bridging from one side of the wall to the other rather than bridging within the plane of the building envelope.
  • EP801190 describes an insulated metal wall construction.
  • the wall is a cassette wall and comprises insulation material that extends outwards beyond the cassette to fill the space all the way up to the outer metal plates and a material strip manufactured from insulating material and dimensioned to absorb pressure forces. This document is also not concerned with decreasing bridging within the plane of the building envelope.
  • 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. This document is, therefore, also only concerned with reducing thermal and acoustic bridging from one side of the wall to the other.
  • An object of the present invention is to provide a system for a building envelope, such as a wall or roof, which reduces the transmission of heat and/or sound through it and in particular from one cassette to another.
  • the reduction of heat and/or sound transfer between the cassettes can also reduce the transfer of heat through the building envelope from one side to the other.
  • a further problem with prior art building envelopes is that often the contact point between the cassettes is not sufficiently air-tight. This could result in the building envelope not meeting the building regulations on air-tightness and could result in heat being lost from the building through convection. Therefore, a further object of the invention is to provide a building envelope with improved air-tightness.
  • the present invention also provides a method according to claim 10 comprising in any suitable order the steps of;
  • the present inventors have found a solution to the problem of thermal and acoustic bridging within the plane of the building envelope 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. They also generally have good fire resistant properties. 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 products including aerogel insulation in the form of a mat.
  • products including aerogel insulation in the form of a mat.
  • One type of mat particularly useful in the present invention is an aerogel matrix composite mat (AMC).
  • AMC aerogel matrix composite mat
  • 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.
  • These 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 particles 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 using the mats to diminish cold bridging. Cassette walls, however, are not mentioned and there is no discussion of thermal or acoustic bridging within the plane of a building envelope.
  • the present inventors have found that by providing a mat comprising from 20 to 95 weight % aerogel between the top plate of the first cassette and the bottom plate of the second cassette, it is possible to provide improved thermal and sound insulation in a building envelope especially in the plane of the building envelope itself.
  • this mat can also improve the air-tightness of the building envelope.
  • air-tightness is measured according to European Standard EN 13829.
  • the mat can be used to improve the air-tightness of a building envelope of the type described in claim 1 relative to a building envelope where the top plate of the first cassette is in direct contact with the bottom plate of the second cassette. This improvement is defined in relation to a building envelope where all other things are equal.
  • the mat has a thickness of no more than 40mm, more preferably no more than 20mm and most preferably no more than 10mm.
  • the aerogel content of the mat must be between 20 and 95 weight % to provide the required properties, but is preferably at least 30, and more preferably at least 40 weight % aerogel.
  • the mat preferably comprises no more than 90, more preferably no more than 80 and most preferably no more than 70 wt % aerogel.

  • the mats will have a thermal conductivity ( ⁇ D -value) of no less than 5, more usually no less than 9 and most often no less than 12 mW/m*K.
  • the mat can be any mat that comprises 20 to 95 wt % aerogel, it is conveniently an aerogel matrix composite (AMC) mat, comprising a matrix of fibres impregnated with aerogel.
  • AMC aerogel matrix composite
  • Mats of this type are commercially available from Aspen Aerogels, Inc. and are made by impregnating a matrix of reinforcing 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 gel.
  • These aerogel matrix composites are mechanically strong and good insulators. 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.
  • the aerogel matrix composite is typically formed by impregnating a fibre matrix with a flowable sol-gel solution. Usually this is a silica-containing sol-gel solution, but suitable aerogels may also be based on alumina or other metal oxides suitable for the sol-gel technique. Aerogel matrix composites may also be made from organic precursors (e.g. as in US 5973015 and 6087407 ). In particular, US5086085 describes aerogels based on melamine formaldehyde condensates and US 4873218 describes aerogels based on resorcinol-formaldehyde condensates.
