Abstract
A thermal insulating material 10 comprising a rear sheet 11, and outer sheet 12 and an insulating material 13 between the two sheets 11 and 12. The two sheets 11 and 12 are sealed by an adhesive or by welding around their edges thereby defining a thicker insulating central portion 14. The rear sheet 11 is a plastics material which has been rendered reflective and the outer sheet 12 is a plastics material which is matt black. Both the sheets 11 and 12 are moisture proof. <IMAGE>
Description
SPECIFICATION
Thermal insulation material
The present invention relates to thermal insulation materials for example materials for use in buildings, in particular for insulating cavity walls, roofs and lofts.
Known insulation materials of this tupe include rolls of glass fibre, rock wool, or alternatively include foam injected into a cavity of an existing cavity wall. The rolls of glass fibre and rock wool exhibit difficulties in handling and, when they are to be used in cavity wall insulation, present problems in attaching the material to the wall. Furthermore, these materials tend to suffer from moisture leakage problems and need to be relatively thick to provide low thermal conductivity. In the case of injected foam materials, it is necessary for the wall to be completed and furthermore, the operation requires specialised equipment and can result in toxic fumes.
It is an object of the present invention to provide a thermal insulation material which can be easily handled in all applications.
It is a further object of the invention to provide an insulation material which can be easily attached to a wall as it is erected.
It is a further object of the invention to provide an acomposite insulation element having a minimum path for water or moisture to penetrate its structure.
It is a further object of the invention to provide an insulation material having a minimum thickness for effective insulation.
It is yet a further object of the invention to minimise intersidual condensation, particularly when used as a composite element in timber frame construction.
According to the present invention, there is provided a thermal insulation material comprising a radiation reflecting surface, a radiation absorbing surface, and thermally insulating means located between the two surfaces, at least one of these surfaces providing a substantially moisture-proof barrier.
Such a material may be located between the two leaves of a cavity wall, preferably with the reflected surface facing inwards and the absorbing surface facing outwards. Thus, radiation from inside a building will tend to be reflected back while radiation from outside the building will tend to be absorbed. This may result in increased thermal insulation in the case of heat tending to pass outwards. Thus, the material may be made thinner and it will therefore be easier to store and transport.
The material may also be easier to install than the injection of foam since it can be erected from the bottom as the wall is built upwards. It may also be easier to handle than glass fibre and rock wool and also easier to attach to a vertical surface. In fact, the material may simply be attached to a wall by means of nails or may be attached between an upper and a lower damp proof course to form a continuous water proof barrier.
Preferably, the radiation reflective surface is a metalised, e.g. aluminised, plastics sheet.
Preferably, the radiation absorbing surface is a plactics sheet rendered dark and preferably matte, e.g. matte black. Preferably, both sheets are moisture-proof.
Any thermally insulating means may be used for example known materials such as glass fibre rock wool, and foam material such as closed-pore polyurethane. Alternatively, the thermally insulated means may comprise air bubbles formed between the two sheets. Air may be trapped between the two sheets by sealing their respective edges together and then sealing, for example by heat, along boundaries over the remainder of the area to define closed voids or bubbles. With such an assembly process which ensures that air is trapped in the voids, the insulation value of the material used to define the voids may be increased. Furthermore, with such a construction minimum moisture leakage can be maintained even when the material of the two sheets will be non-uniform in its thickness to define parts that will swell to form the voids and bubbles when the two sheets are sealed together.
The invention may be carried into practice in various ways and some embodiments will now be described by way of example with reference to the accompanying drawings in which:
Figure 1 is a sketch showing a first embodiment of a thermal insulation material in accordance with the present invention;
Figure 2 is a view similar to Fig. 1 showing a second embodiment; and
Figure 3 is a sectional sketch of a material in accordance with the embodiment shown in
Fig. 2 in position for use on a portion of a cavity wall.
Fig. 1 shows a portion of a first embodiment of a thermal insulating material 10. The material 10 comprises a rear sheet 11, an outer sheet 12, and insulation 13 between the two sheets 11, 12. The two sheets 11, 12 are sealed, for example, by an adhesive or by welding, or are heat sealed around their edges to define a thicker insulating central portion 14.
The rear sheet is composed of a plastics material which has been rendered reflective for example by applying a layer of aluminium alloy. The outer sheet 12 is a plastics material which is matte black in appearance. Conveniently, in each case, the plastics material has the ability to "breath" without transmitting moisture through its mass.
The insulation in this case can be glass fibre, rock wool, or a foamed plastics material such as closed-pore polyurethane.
The material 10 can be manufactured in any required shape though it is preferably in the form of a long sheet which can be rolled.
Fig. 2 shows a portion of a second embodiment of a thermal insulation material 20. The material 20 comprises a rear sheet 21 and an outer sheet 22 which are similar to the sheets 11 and 12 of the embodiment of Fig. 1. However, in the case of the material of the second embodiment, there is no insulation per se. Instead, the two sheets 21, 22 are sealed at their edges trapping air between. The two sheets 21, 22 are then heat sealed along boundaries 24 to define a large number of sealed bubbles 23 which provide the insulation. The bubbles 23 are shown as being square but could be any convenient shape for example round.
The material 20 shown in Fig. 2 is shown in position, in use in Fig. 3. A section of the insulation material 20 is shown in position in a cavity wall 31 which comprises an inner leaf 32 and an outer leaf 33. The material 20 is attached to the inner leaf 32 conveniently by means of nails (not shown). The nails might pass through positions where the two sheets 21, 22 are joined, i.e. along the boundaries 24, though this is not strictly necessary. As will be appreciated, the rear reflective sheet 21 is adjacent to the inner leaf 32 and the outer radiation absorbing sheet 22 faces the outer leaf 33. Thus, radiation from within the building will tend to be reflected back while radiation from outside the building will tend to be absorbed.
