According to the present invention there is provided an apparatus and method as set forth in any appended claims. Other features of the invention will be apparent from any dependent
claims, and the description which follows.
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 shows a side sectional view of a composite wall structure in accordance with an example embodiment of the present invention; and Figures 2A and 2B show a front views of a composite wall structure in accordance with another example embodiment of the present invention.
Referring now to Figure 1 there is shown a side section view of a composite wall structure 1, in accordance with an example embodiment of the present invention. The composite wall structure 1 is intended to form an exterior wall in a house, or other similar building. The exterior of the building is denoted E and the interior of the building is denoted I. The composite wall structure aims to provide excellent thermal insulation, while at the same time being of simple construction, employing mainly sustainable and recyclable materials, and adequately dealing with condensation/moisture control in the composite wall structure/building.
The composite wall structure 1 comprises a breathable enclosure containing plant-based insulating material core 10 and a moisture absorbing material. The composite wall structure also comprises a superstructure 30 at least in part framing the wall, which is shown in Figure 1 in dashed lines as hidden detail. The core 10 is made up of bales of straw. The moisture absorbing material comprises lambs' wool fleece. Ideally, dried straw is used in the composite wall straw structure. However, a degree of moisture may remain in straw bales, or dry straw bales may be wetted by rain or condensation during the construction of the composite wall structure. Excess moisture in the straw bales may lead to rotting or other problems within the composite wall structure. The lambs' wool fleece material is arranged with the straw bales to absorb moisture there-from, and to safely lock in the moisture to reduce problems associated with moist straw. The lambs' wool fleece material is also itself a good thermal insulator, even when wet, which when used with the straw bales maintains good overall the insulating properties.
In particularly preferred examples, the superstructure defines the edge regions of the composite wall structure, and where required also defines openings in the wall such as windows or doors. Figures 2A and 2B show the core 10, superstructure 30 and moisture absorbing material 20 in a composite wall structure resting on foundations F. The superstructure 30 frames openings 32 in the composite wall structure 1 to provide a sound structural base for associated window frames, door frames etc. The superstructure 30 comprises an open, wooden trellis construction. The moisture absorbing material 20 is provided in the superstructure 30 to substantially fill the open voids between struts in the superstructure 30. In this way a sound structural basis for the composite wall structure 1 is provided, with the core 20 making up the majority of the composite wall structure 1 and providing the majority of the thermal insulation, whereas the superstructure 30 and associated moisture absorbing material 20 giving added structural integrity and enabling the insulating moisture absorbing material 20 to simply be stuffed into the superstructure 30 as the composite wall structure 1 and building takes shape.
The superstructure 30 is conveniently arranged to receive bales of insulating material of a predetermined dimension to build up a core 10 of the composite wall structure I within the superstructure 30. The superstructure 30 defines an insulation depth dimension d that comprises a depth approximately equivalent to a standard straw bale width, for example 450mm. The superstructure 30 also defines an internal height and width dimensions equivalent to an integer multiple of a height or length of a standard straw bale. For example, the height of a standard straw bale is 350mm, so a core 10 of e.g. 2.8m per storey may be conveniently constructed. The width of the composite wall structure may conveniently be based on a core 10 of a multiple of 900mm, as 900mm is the length of a standard straw bale.
The breathable enclosure comprises a breather membrane 12 provided over a face of the composite wall structure 1. The breather membrane 12 is provided over substantially the whole of a face of the composite wall structure 1, external of the core 10 and at an exterior portion of the core 10. The breather membrane 12 is provided in contact with an exterior portion of the core, across the exterior portion of the core. The breather membrane 12 may for example comprise a FRAMEWRAPTM membrane available from DuPontTM, such as DuPontTM 5810X. This type of material has, according to published data at 13 October 2008, a water tightness of class W2 when tested according to EN 13111 and a nominal vapour transmission coefficient (Sd) of 0.Olm when tested according to EN ISO 12572.
The composite wall structure 1 further comprises a weather-proofing portion 40, arranged outward of the core 10 and the breather membrane 12. The weather-proofing portion 40 comprises a particle board material extending substantially across the whole face of the composite wall structure and a two-skim render applied to the particle board covering. The particle board, and/or other parts of the weather-proofing portion 40 are fire resistant, for example having a 30 minute fire rating to protect the core 10.
The composite wall structure 1 comprises a first coupling portion 50 arranged to join the superstructure 30 to the weather-proofing portion 40. The first coupling portion 50 comprises battens running across an interior face of the weather-proofing portion 40, coupled to the superstructure 30, or to another structural support at the top and bottom of the composite wall structure 1, and leaving the majority of the breather membrane 12 open to allow moisture to escape therefrom..
The composite wall structure I further comprises an interior finish portion 60, arranged inward of the core 10. The interior finish portion 60 comprises a plaster board material extending substantially across the whole interior face of the composite wall structure. The composite wall structure 1 comprises a second coupling portion 70 to join the superstructure 30 to the interior finish portion 60. The second coupling portion comprises vertical battens 72 running vertically across an exterior face of the interior finish portion 60, and horizontal battens 74 running horizontally there-between. The second coupling portion 70 is arranged to maintain an air gap between the core and the interior finish portion 60. The air gap 80 may conveniently be used to house wiring or other services, and if used in this way the need to disturb the core 10 in the first fix or subsequent installation of services is avoided.
Fire and moisture proofing is provided between the air gap 80 and the core 10. A moisture control layer 82 is provided. The moisture control layer may also comprise breather membrane comprising a FRAMEWRAPTM membrane as described above. To prevent warm, moisture carrying air from passing into the core 10 the moisture control layer 82 may alternatively be a vapour barrier such as TYVEKTM 8327AD produced by DuPontTM This type of material is intended to reduce the incidence of condensation within the core 10. TYVEKTM 8327AD has, according to published data at 8 May 2009, a nominal vapour transmission coefficient (5d) of 5m when tested according to EN 1931 and a nominal density of water vapour flow rate coefficient (g) of 0.8x107 kgl(m2s) when tested according to EN 1931.
A layer of orientated strand board 84 is provided to give a degree of fire protection, in case that services provided in the air gap 80 ignite, or in case of any other potential source of fire being introduced into the air gap 80. The orientated strand board 84 also gives a degree of structural reinforcement, being coupled to the core 10.
By joining the first and second coupling portions to the superstructure 30 the core 10 remains undamaged, which reduces the chance of water ingress and avoids establishing thermal bridges into the core 10.
As above, composite wall structures and methods of assembly thereof have been described.
The material and construction choices outlined herein provide suitable thermal insulation properties, are easy to work with and perform, are largely sustainable and recyclable and avoid moisture problems.
