Abstract
A settable lubricious material, such as silicone, is applied to loose fibres, such as glass or rockwool, and the fibres are then injected into a cavity (5) between two rigid building panels (2, 3), via at least one opening (6) to fill the cavity. The silicone material minimises the degree of obstruction presented to the fibres when passing around obstacles such as spacer bars (4). When the silicone sets the fibres are bound together so that panels may be replaced without the loss of insulation. Preferably the building panels are metal or plastics profiles and may form a gutter (Figure 2).
Description
<Desc/Clms Page number 1>
A Method of Thermally Insulatina a Cavity between Panels of Buildina Material The present invention relates to thermally insulating cavities between panels of building material and relates particularly, but not exclusively to a method of thermally insulating a cavity between inner and outer skins of building, and to a method of forming a thermally insulated factory-assembled gutter.
In many countries, legislation defining performance of thermal insulation in new or existing buildings is becoming increasingly stringent, primarily for environmental reasons.
In buildings consisting of an inner and outer skin separated by spacers and defining a cavity containing insulating material such as glass wool or rock wool provided in rolls or sheets, the requirement for better thermal insulation performance in effect means that thicker insulation, and thus wider cavities, are necessary than in the case of the prior art.
However, prior art buildings of this type suffer from the drawback that as the cavity between the inner and outer skins of the building becomes wider, the structural integrity of that part of the building becomes increasingly difficult to ensure. Also, because the insulating material in prior art building structures is provided in the form of continuous sheets or rolls and the inner and/or outer skins of the building are in the form of rigid sheets which are profiled with channels for strength, it is difficult to fill all of the cavity and/or fit the insulating material around the spacers. This generally results in gaps in the insulating material, which has a detrimental effect on the thermal performance of the insulating material.
<Desc/Clms Page number 2>
Insulated gutters are also known, which consist of a pair of fabricated metal sheets defining a channel, which are bonded to a correspondingly profiled sheet of insulating material between the metal sheets. Prior art gutters of this type suffer from the drawback that because of the irregular shape and different materials of the sheet to be bonded to each other, high quality joints between adjacent sheets are difficult to achieve, with the result that bonding between adjacent sheets can break down.
Preferred embodiments of the present invention seek to overcome the above disadvantages of the prior art.
According to an aspect of the present invention, there is provided a method of applying thermally insulating material to a cavity between substantially rigid panels, the method comprising the steps of :- applying a settable lubricious material to loose fibres of thermally insulating material; and injecting at least some of said fibres to which said lubricious material has been applied into a cavity between substantially rigid panels to substantially fill said cavity.
By applying a settable lubricious material to loose fibres of thermally insulating material and subsequently injecting the fibres into the cavity to substantially fill the cavity, this provides the advantage that the cavity can be filled to a much greater extent than in the case of prior art rolls and sheets of thermally insulating material, even if spacers are present between the sheets, while subsequent setting of the lubricious material limits the extent to which the fibres are lost when the cavity is opened, for example to replace panels in the outer skin of a building. This result is highly surprising,
<Desc/Clms Page number 3>
since settable lubricious materials have not hitherto been used to bind loose fibres of insulating material together but rather as a moisture repellant, and there would be a strong prejudice in the relevant technical field against using loose fibres of insulating material in cavities in buildings, since such fibres would be expected to be blown away when the cavity is opened to the atmosphere to carry out repairs to the outer skin of the building. In addition, injection of the fibres into the cavity enables a better degree of thermal insulation to be achieved (or a narrower cavity for the same degree of insulation) than the prior art, and at less cost because of the more simplified procedure involved. The thermally insulating material can be applied in a factory or on site.
The method may further comprise the step of providing one or more apertures in at least one said panel to enable injection of at least some of said fibres through at least one said aperture.
Respective said panels may form part of inner and outer skins of a building structure.
In a preferred embodiment, the or each said aperture is provided in said inner skin.
This provides the advantage of minimising effects of the weather on the thermally insulating material.
The method may further comprise sealing the edge regions of said cavity to minimise escape of said fibres.
In a preferred embodiment, said substantially rigid panels form part of a composite panel of building material.
<Desc/Clms Page number 4>
This provides the advantage of enabling composite panels of building material, such as composite panels for forming thermally insulated gutters, to be made with a higher degree of thermal insulation than in the prior art, for example because of higher quality joints between adjacent layers of the composite panel.
Said composite panel may be adapted to form part of a gutter.
At least one said panel may be formed substantially of metal.
At least one said panel may be profiled.
Said lubricious material may comprise a silicone material.
The method may further comprise the step of setting said lubricious material.
Said setting step may comprise curing.
According to another aspect of the present invention, there is provided a composite panel comprising :- at least two substantially rigid panels defining at least one cavity therebetween; fibres of thermally insulating material substantially filling at least one said cavity; and set lubricious material bonding said fibres together in at least one said cavity.
The composite panel may further comprise sealing means sealing at least one edge region of said panel.
<Desc/Clms Page number 5>
At least one said substantially rigid panel may be formed substantially of metal.
At least one said substantially rigid panel may be profiled.
Said lubricious material may comprise a silicone material.
Preferred embodiments of the invention will now be described, by way of example only and not in any limitative sense, with reference to the accompanying drawings in which :- Figure 1 is a schematic illustration of the application of thermal insulation to a cavity between inner and outer skins of a building by means of a method embodying the present invention; and Figure 2 is a cross-sectional view of a composite gutter panel formed by means of a method embodying the present invention.
Referring to Figure 1, a building 1 is formed from an inner skin 2 and an outer skin 3 separated by regularly spaced spacer bars 4 to define a cavity 5. One or more openings 6 is provided in the inner skin 2 to allow injection of thermally insulating material. A settable lubricious material such as a silicone material is applied to loose fibres of short length of thermally insulating material such as glass or rock wool, and the fibres are then injected into the cavity 5 via opening 6 to substantially fill the cavity. The silicone material minimises the degree of obstruction presented to the fibres in passing around spacer bars 4. When the silicone material sets the fibres are bound together, so that panels of the outer skin 3 of the building can be replaced without loss of insulation when the panel is removed.
<Desc/Clms Page number 6>
Figure 2 shows a composite insulated gutter panel 10 formed from spaced apart profiled sheets 11,12 of stainless steel to define a cavity 13. The panel 10 is formed by placing the sheets 11,12 in a suitable holder (not shown) and placing seals 14 around the edge regions of the panel. Loose fibres of thermally insulating material to which settable silicone material has been applied are then injected into the cavity 13 through a suitable aperture (not shown) and the thermally insulating material holds the panel together when it sets. To form a gutter from one or more of the panels 10, the seals 14 are removed and the panels 10 connected together.
It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims. For example, it will be appreciated that the profiled sheets 11, 12 can be made from any suitable metal or plastics material.
