Description

I A BUILDING SYSTEM TECHNICAL FIELD
[0001] The present invention relates to the building industry and, more particularly to building cladding system.
BACKGROUND
[0002] Cladding is used to cover a stud frame of a building. It is a light-weight and cheaper alternative to brick work.
[0003] A popular form of cladding is Autoclaved Aerated Concrete ("AAC") panels. AAC panels are used to form external walls or facades of homes, internal walls of buildings, as flooring, fencing, sound barriers, fire walls, acoustic walls and fire tunnels.
[0004] However, AAC panels are heavy to lift. Most AAC panels has dimensions of 2,700 mm x 600 mm x 75 mm and weigh approximately 90 kg. They require at least two men to
manoeuvre on site.
[0005] The panels have to be cut with a circular saw on site in order to customize them for the particular building application. However, AAC panels contain silica dust. Silica dust is known to be toxic. It causes a condition called "Silicosis". Silicosis is caused by inhaling particles containing crystalline silica. Silicosis takes at least 10 years to develop after the first exposure, and death typically does not occur until several years later. There are ways to reduce dust exposure, such as using vacuum saws. However, novice, inexperienced or unlucky workers can still become inadvertently exposed to the silica dust.
[0006] An alternative to AAC panels are Expanded Polystyrene (EPS) panels. An advantage of EPS panels over AAC panels is that they are much lighter. EPS panels typically weigh only about 5 kg and can easily be manoeuvred on site by a single person. AAC panels are stronger than EPS panels, but AAC panels are more brittle. If an AAC panel is dropped, then it can shatter. EPS panels are more resistant to breakage. However, a major problem with EPS panels is that they are known to be highly flammable. They have a zero fire rating. Although EPS panels are rendered in a layer of concrete, if the concrete render is exposed to fire, then the EPS panel melts behind the concrete render. Many buildings have AAC panels on the ground floor and EPS panels on the top floor.
[0007] A building made of brick takes a lot longer to construct than a building made of EPS panels. It can take about a day for a house to be clad in EPS panels, but over two weeks for the same house to be built from bricks.
[0008] Brickwork heats up in the sun and traps the heat. During the day the heat is transferred to the house. At night the bricks get cold and stay cold. EPS panels have better insulation characteristics than AAC panels or brickwork.
[0009] Overall, EPS panels provide a superior form of building material to AAC panels and brickwork. Nevertheless, EPS panels suffer from the drawback of a zero fire rating.
[0010] Mineral wool panels are another cladding option. They are non-combustible, non-toxic and lightweight. Mineral wool panels can be attached to chipboard, sheet bracing, brickwork or other solid substrates. However, they cannot be attached to a bare stud frame because they are not strong enough to be affixed. Mineral wool panels are not a rigid product, so they sag, bow and bend over time due to the need to span a distance of up to 600mm between studs. They have a similar composition to a dense insulation bat and they can be torn with the hands. However, using solid substrates adds a cost to the building process which reduces profitability. Using solid substrates is not the common practice in many countries, such as Australia.
[0011] In Australia, houses are typically built with timber or metal stud frames. In Europe, houses are typically built with brickwork. In the US, houses are typically built with timber or metal stud frames covered with chipboard sheet bracing.
[0012] The object of the present invention is to provide a mineral wool panel adapted to be attached to a bare stud frame which is rigid enough to span between the stud spacings.
SUMMARY OF THE INVENTION
[0013] According to the present invention, there is provided a building system comprising:
(a) a stud frame; (b) a mineral wool panel; and (c) fasteners, wherein the building system has a mesh layer attached to the mineral wool panel which is then fastened to the stud frame to provide the mineral wool panel with strength and rigidity.
[0014] Preferably, the mesh layer is made from fibreglass, but may also be made from a metal, or other material. It is preferred that the mesh layer is attached to the mineral wool panel by gluing, rendered directly onto the mineral wool panel, nailed, stapled or attached by any other
-Y
form of fastener. The mesh layer is attached to the mineral wool panel at a factory and brought to the building site as a single unit.
[0015] More than one layer of mesh may be used. For example, on one or both sides of the mineral wool panel.
[0016] It is also preferred that the system also includes a membrane attached to the stud frame. The membrane is preferably made of paper, but may be made of other materials, such as fibreglass, aluminium foil or woven cloth. The membrane protects the building against radiant heat, it contributes to the overall energy rating of the building, it minimises the amount of moisture absorbed by the frame during construction and acts as an effective secondary skin on the building to minimise draughts within wall cavities so as to insulate the building more effectively.
[0017] The building system may include battens attached to the paper membrane. The mineral wool panel may be attached to directly to the stud frame through the paper membrane, or onto the battens interposed between the mineral wool panel and the stud frame to pack out the wall or to make a cavity system.
[0018] The building system may include one or more coats of render over the mineral wool panel.
BRIEF DESCRIPTION OF DRAWINGS
[0019] Embodiments of the invention will be described with reference to the following drawings, in which:
[0020] Figure 1 is perspective view of a prior art building system using EPS panels on battens.
[0021] Figure 2 is a close up cut-away view of the prior art building system of figure 1.

[0023] Figure 4 is a close up view of the building system of figure 3.
[0024] Figure 5 is a perspective view of a building system according to a second embodiment of the present invention.
[0025] Figure 6 is a close up view of the building system of figure 5.
DETAILED DESCRIPTION
[0026] Figures 1 and 2 shows a prior art building system 10. The system 10 comprises a building stud frame 12, a paper membrane 14, battens 16, an EPS panel 18, screws 20, washers 22, a render coat 24. A problem with this prior art system 10 is that it is not fire-proof. The EPS panel 18 will melt if the exterior of the prior art building system 10 is exposed to high heat or a naked flame.
[0027] A mineral wool panel is not as combustible as an EPS panel. However, it cannot be attached to the stud frame 12, because it will sag, bow or bend over time.
[0028] Figures 3 and 4 shows a building system 26 according to a first embodiment of the present invention. The system 26 comprises a stud frame 28, a paper membrane 30, battens 32, a mineral wool panel 34, a mesh layer 36, screws 38, washers 40 and render coats 42.
[0029] The mesh layer 36 supports the mineral wool panel 34. The mesh layer 36 is made from fibreglass and is glued to the mineral wool panel 34. The washers 40 are placed over the mesh layer 36 and assist in holding the mesh layer 36 in position. The screws 38 go through the washers 40, through the mesh layer 36, through the mineral wool panel 34, through the battens 32, through the paper membrane 30 and into the stud frame 28. The mesh layer 36 acts as large washer that provides the mineral wool panel 34 with greater structure and rigidity.
[0030] Figures 5 and 6 show a second embodiment of the building system 26 according to the present invention. The second embodiment has a mesh layer 33 on the rear of the mineral wool panel 34 and the mesh layer 36 on the front of the mineral wool panel 34. This provides the mineral wool panel 34 with even greater structure and rigidity.
[0031] The building system 26 thereby enables the mineral wool panel to be attached to a bare stud frame. This provides the advantages of low combustibility, use of lightweight materials, and non-toxic material.
