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 compressive stress at 10% compression or, where appropriate, the compressive strength is tested according to European Standard EN 826:1996.
- the mat has a compressive stress at 10% compression of at least 40 kPa or, if 10% compression is not reached before the maximum compressive stress, has a compressive strength of at least 40 kPa. More preferably, the mat has a compressive stress at 10% compression of at least 60 kPa or, if 10% compression is not reached before the maximum compressive stress, has a compressive strength of at least 60 kPa.
- the compressive stress at 10% compression or, where applicable, the compressive strength is as high as possible.
- the mat has a compressive stress at 10% compression of no more than 120 kPa, more usually no more than 100 kPa or, if 10% compression is not reached before the maximum compressive stress, has a compressive strength of no more than 120 kPa, more usually no more than 100 kPa.
- 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 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.
- the stated weight % does, however, include substances like hydrophobizing agents and IR opacity substances for the aerogel material.
- the aerogel content of the mats used in the present invention will result in good insulation properties.
- the mat has a thermal conductivity ( ⁇ D -value; based on measurements in accordance with European Standard EN 12667 at a reference mean temperature of 10 °C) of less than 30, more preferably less than 22 and most preferably less than 17 mW/m*K.
- 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% aerogel and has the required resistance to compression, it is conveniently an aerogel matrix composite (AMC) mat, comprising a matrix of fibres impregnated with an 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 resorcinolformaldehyde condensates.
- the mat used in the present invention is preferably an aerogel matrix composite, that has been formed by drying under supercritical conditions.
- the fibres that form the matrix of an AMC may be of any suitable material, but preferably the fibre matrix comprises polymer fibres, mineral fibres, ceramic fibres, glass fibres or mixtures thereof. Due to the strength they impart to the mat as well as their fire-resistant properties, the fibres are more preferably mineral fibres, ceramic fibres, glass fibres or mixtures thereof. Preferably the fibres are in the form of a wool.
- the mat may comprise aerogel in the form of particles which may optionally be held in the mat with a binder.
- the mat comprising aerogel particles may also optionally comprise fibres.
- the fibres are preferably polymer fibres, mineral fibres, ceramic fibres, glass fibres or mixtures thereof. Most preferably they are mineral fibres.
- mats comprising aerogel in the form of a particulate suitable for use in the present invention are described in US 6485805 , US 6479416 and WO2006/065904 .
- the mat prefferably be single block or sheet comprising from 20 to 95 weight % aerogel or a plurality of aerogel blocks or sheets combined to form the mat.
- the mat comprises a metal or silicon oxide aerogel, more preferably a silicon oxide aerogel.
- the mat used in the present invention preferably comprises aerogel that has been formed by drying under supercritical conditions.
- the present invention is most useful in a partition wall that separates two interior rooms within a building. In such applications, it is important to provide good sound and thermal insulation, but also to provide a wall that has good strength, and is relatively thin, whilst also being economical to produce.
- the wall of the present invention comprises two panels that define the surfaces of the wall. These panels may be any suitable panel, for example, gypsum plasterboards or chipboards. It is even possible for one of the panels to be in the form of a brick wall panel. However, it is preferred that the panels are gypsum plasterboards or gypsum fibreboards.
- a sheet of sound and/or thermal insulating material is located between panels.
- the sheet may be formed of any sound and/or thermal insulating material known in the art. However, due to its flexibility, and fire-resistant properties, it is preferred that the sheet of insulating material is a man-made vitreous fibre batt. It is also possible, however, to incorporate aerogel into the sheet of insulating material.
- the man-made vitreous fibre batt has a density of between 10 and 150 kg/m 3 , preferably between 20 and 100 kg/m 3 and more preferably between 30 and 70 kg/m 3 .
- the fixing element is positioned between the first and second panels.
- the fixing element extends at least in part inboard of the edges of the first and second panels and extends beyond the edge of the sheet of insulation material.
- the fixing element usually has a spacer between the first side surface and the second side surface.
- the spacer serves to separate the two panels and provides space for the sheet of sound and/or thermal insulating material.
- the spacer usually extends in a plane substantially perpendicular to the first and second panels.
- the spacer may be of any suitable form. However, it is preferable that the spacer is in the form of a back-plate.
- the fixing element also comprises first and second side surfaces, which are in a plane substantially parallel to the planes of the first and second panels and usually substantially perpendicular to the spacer, when the spacer is present.
- the side surfaces may take any suitable form.
- the fixing element may be a simple block, wherein the central portion of the block is the spacer and the side surfaces are the surfaces of the block that face the first and second panels and are for affixing the side panels.
- the spacer is in the form of back-plate, that the side surfaces are formed on side plates.
- the fixing element may be in a number of forms. Two of the preferred forms those of a C-profile or a U-profile, wherein the back-plate has two side-plates extending in the same direction, perpendicularly to and from each end of the back-plate. Other preferred forms are I-profiles and H-profiles wherein the ends of the back-plate are attached to substantially the centre of each side plate.
- the fixing element may be made of any suitable metal, but it is usually made of steel.
- the first panel is attached to the first side surface and the second panel is attached to the second side surface.
- the preferred manner of attachment will depend on the form and material of the respective panel and fixing element, and could be nails, rivets, staples or any other suitable means.
- the preferred method of fixing the side surfaces of the fixing element to each respective panel is with screws. Preferably, several mutually spaced screws are used.
- the panel is preferably attached to the fixing element with screws that have a substantially uniform diameter along substantially the entire length of the shaft of the screw. It is also preferred that the thread of the screw is substantially continuous along substantially the entire length of the shaft of the screw.
- the mat comprising aerogel is positioned between the first side surface and the first panel.
- This positioning of the mat serves to decrease the transfer of heat and/or sound through the fixing element from one side of the wall to the other.
- the mat is only required to separate the first side surface from the first panel, it is also possible to further improve the insulation by providing a second mat comprising from 20 to 95 weight % aerogel positioned between the second side surface and the second panel, the mat having a compressive stress for 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.
