Abstract

An inflatable heat insulation member 1 for insulating buildings and the like, comprises an interior divided into a plurality of discrete cells for filling with a gas having a low thermal conductivity and an outer skin of gas impermeable material. The member 1 may be portable, and inflated with e.g. air, argon, krypton, CO2 or SF6 from a cylinder 6. <IMAGE>

Description

HEAT INSULATORS The present invention relates to inflatable heat insulation members and methods of heat insulation utilising inflatable members.
Fibrous material such as Rockwool containing a large proportion of trapped air is a well known heat insulating material and is widely used to insulate the walls and roof spaces of buildings.
Gases generally have a very low thermal conductivity as compared to solids and liquids. However, with gases, convection is a prime means of heat transfer and convection must be prevented or inhibited before the full potential of gases as heat insulators can be exploited.
A further aspect of insulation members is that most currently in use are permanent in nature and are not susceptible to easy removal and storage.
It is one aim of the present invention to utilise the low thermal conductivity of gases to provide an inflatable heat insulation member in which convection is kept to a minimum.
It is a further aim to provide an inflatable heat insulation member which is easy to install and relatively easy to store when not in use.
According to the present invention, an inflatable heat insulation member has an interior divided into a plurality of discrete cells and an outer skin of gas impermeable material.
Preferably, when in use, the inflatable heat insulation member is inflated with a gas having a low thermal conductivity.
Preferably, the gas is selected from one or more of air, argon, krypton, carbon dioxide and sulphur hexafluoride.
Advantageously, the inflatable insulation member may be portable.
According to a further aspect of the present invention a method of insulation comprises the steps of placing an inflatable insulation member having an interior divided into a plurality of discrete cells and an outer skin of gas impermeable material between an area to be insulated and an area from which said first area is to be insulated and inflating said inflatable insulation member with a gas having a low thermal conductivity.
An embodiment of the invention will now be described by way of example, reference being made to the Figures of the accompanying diagrammatic drawings in which: Figure 1 is a perspective view of an inflatable insulation member; Figure 2 is a detail in cross-section of the inflatable insulation member of Figure 1; Figure 3 is an elevation partly in cross-section of a building with the inflatable insulation member of Figure 1 in situ; and Figure 4 is an elevation similar to Figure 3 but illustrating the inflatable insulation member deflated.
As shown, an inflatable insulation member 1 is in the form of a mattress made from a flexible material such as a plastics or rubberised cloth which is leak tight or has a low permeability to the gas being used to inflate the mattress.
The mattress includes a gas inlet valve 2 and as will be most clearly seen from Figure 2, its interior is compartmentalised to define cells or pockets 4. The cells or pockets 4 reduce the ability of the gas to flow and thereby exhibit thermal convection.
The compartmentalisation can be achieved by methods such as the use of flaps or an inter- weave of the material of the mattress.
It should be pointed out that the gas cells or pockets are not totally sealed one from another but, for example, can be porous so that the mattress can be fully inflated and deflated.
The choice of gas used to fill the mattress is based on its thermal insulating properties and on its costs. For example: cheapest Air k - 255 pW/cm C Argon k - 162 pW/cm C C02 k - 162 pW/cm C SF6 k - 130 pW/cm C Krypton k - 86 pW/cm C An important feature of the inflatable insulation member illustrated in Figure 1 is its lightness and the ease by which it can be installed in a building. This will entail unfolding the mattress in its uninflated state over the area to be insulated. The mattress will have relatively little bulk compared to conventional insulating materials such as Rockwool.The mattress will then be inflated by means of compressed gas/gases and the inflated insulation member can then be sealed and left or remain connected to the source, e.g. a compressed gas cylinder 6, of compressed gas as illustrated in Figure 3. Preferably, the gas in the mattress will be maintained at just above atmospheric pressure. Compressed gas can therefore be added from the cylinder 6 if the pressure drops due to leaks/diffusion.
When used as roof insulation the material of the mattress can be transparent or transluscent to allow light therethrough.
Alternatively, one or both interior surfaces of the mattress can have an aluminium coating to reduce heat transfer by radiation.
In summer, when there is less need for heat insulation the mattress can be removed easily by deflating the mattress and folding it up so that it can be stored until required again. Figure 4 illustrates a mattress deflated which, however, in this instance, has remained in situ.
Although the above described embodiment of the mattress is shown and described as a roof insulator it can as easily be used as a wall insulator.
The inflatable insulation member described above is environmentally friendly as compared to Rockwool, fibreglass and expanded polytyrene.
