Abstract
An insulating material comprises a sheet 10 of bubble pack plastics material laminated on both sides with low emissive Aluminium foil. The sheet is sealed along one longitudinal edge to provide a flange 11 of between 20mm and 30mm. The flange is suitable for embedding into a cement joint in a wall. The insulating material is preferably used to insulate the edge of a floor slab against cold bridging.
Description
<Desc/Clms Page number 1>
IMPROVED FLOOR INSULATION Field of the Invention
The present invention relates to an improved apparatus for insulating floors. It is particularly applicable, but in no way limited, to the insulation of pre-stressed concrete floors.
Background to the Invention
Pre-stressed concrete floors are used extensively by the construction industry in both commercial and domestic premises. Whilst this type of floor construction offers a number of advantages in terms of speed of construction and cost, the resultant floor has limited thermal insulation properties which are determined by the thickness and type of material used. That is to say a pre-stressed concrete floor has an inherent U value which can only be altered by adding further layers of insulation. There is a everincreasing pressure to improve the thermal insulation property of floors and this is reflected in tougher building regulations. In the case of pre-stressed concrete floors this is typically achieved by adding one or more layers of insulating material on top of the floor once it has been laid. However, since construction continues after the floor has been installed, this insulation is prone to damage.
Alternatively, concrete with improved insulating properties can be used.
However, this tends to adversely affect the other properties of the floor, such as its strength and also results in a considerable increase in cost which the customer is unwilling to bear.
The present applicants earlier UK patent application no GB 2,326, 652A discloses a method and apparatus for addressing these problems which involves securing an insulating membrane of plastics film laminated with aluminium foil suspended across the floor void beneath the floor. This provides substantial benefits
over earlier systems for floor insulation. However, this approach is not universally 1
<Desc/Clms Page number 2>
appropriate and does not insulate to the outside edge of a floor slab where the floor is in contact with a wall.
It is a general object of the present invention to specifically address the problem of insulating the edge of a floor slab against cold bridging in a simple and cost effective manner, improving the U value of the floor.
Summary of the Invention According to a first aspect of the present invention there is provided an insulating material comprising a sheet of bubble pack plastics material laminated on both sides with low emissive Aluminium foil and sealed along one longitudinal edge only to provide a flange which is 20 to 30 mm in extent.
Preferably the insulating material has a flange which is 25 mm in extent extending into the joint, suitable for insertion into a cement joint in a brick or block wall.
According to a second aspect of the present invention there is provided an insulating material as hereinafter described with reference to the accompanying drawings.
Brief Description of the Drawings A preferred embodiment of the present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, wherein : Figure 1 is a perspective view of a part assembled cavity wall at ground floor level and showing the installation of a sheet of insulating material to shield the outer edge of a concrete floor slab, where the slab is mounted along one edge in the inner leaf of the cavity wall.
Figure 2 is a transverse sectional view through a cavity wall similar to that illustrated in Figure 1 and further illustrating the placement of the insulating sheet.
<Desc/Clms Page number 3>
Description of the Preferred Embodiment
Referring to the Figures, a pre-stressed concrete floor slab 1 is supported above the level of the ground by the blocks of an inner leaf 2 of a cavity wall.
The part-assembled cavity wall illustrated comprises an inner leaf 2 of blockwork and an outer leaf 3 of brick both supported on a two layer thick foundation of trench blocks 4a, 4b.
Three layers, which may otherwise be described as rows or courses, of the block work of the inner leaf 2 are shown. A first course 5a set atop the trench block 4a supports the pre-stressed concrete floor slab 1 by an outer longitudinal edge of the floor slab 1. The second row of blocks 5b sits atop the floor slab 1 and the third row of blocks 5c, in turn, sits atop the second row of blocks 5b. The blocks 5a, 5b and 5c together with the edge of the floor 1 are jointed with mortar between the layers and between each block in each layer.
The outer leaf 3 of the wall formed of brickwork is also jointed with mortar.
An aeration duct 6 is illustrated in Figure 2 extending from the exterior of the wall through the outer leaf 3 across the cavity and through the inner leaf 2 of blocks in order to aerate the under floor void.
Thus far described the construction of the cavity wall and floor is substantially conventional with the exception of the fact, as discussed earlier, that it is conventional to use three layers of trench blocks 4 rather than simply two. The ability to dispense with the third layer of trench blocks 4 and, furthermore, to in some instances dispense with any under floor insulation arises from the use of a sheet of insulating material that is-positioned within the cavity of the cavity wall in the manner described below.
The sheet of insulating material 10 is suitably a single layer of plastics (e. g. polyethylene) bubble pack laminated on both sides with low emissive aluminium foil. In contrast to such thermal insulating sheets as are currently available, however, this
<Desc/Clms Page number 4>
sheet is compressed and sealed along one longitudinal edge to form a flange or fin 11.
The sheet is suitably supplied in roll form of the order of 525 mm in width to lengths of, for example, 50 metres. The selected width is generally sufficient to span the average height of two standard building blocks separated by a concrete floor slab.
The sheet 10 is unrolled and installed into the cavity of the cavity wall either before the outer leaf 3 begins to be constructed or after only the first few brick courses have been laid.
As will be seen from Figures 1 and 2, the flange or fin 11 of the sheet 10 is adapted to be readily inserted into the mortar joint between the course 5b of blocks immediately atop the floor slab 1 and the course 5c above that. The flange or fin 11 is suitably of the order of 25 mm in depth and should be substantially fully embedded into the mortar joint and the sheet 10 allowed to hang down to the base of the cavity. It is suitably tightened to be as taught as possible to the face of the block work 2 and dressed down to the top of the trench block 4a or the bottom of the cavity as illustrated.
To facilitate holding the sheet 10 in place it can occasionally be nailed to the block work 2.
For most purposes it is generally easiest to fit the sheet 10 loosely in place in the cavity prior to raising the brick outer leaf 3 above the normal level of damp proof course and fitting the flange 11 in place.
The sheet 10 is suitably marked with an orientation marker so that the user knows which face of the sheet 10 must be presented to the face of the blockwork inner leaf 2.
Where there is an air vent 6 present, as illustrated in figure 2, the sheet 10 should be cut and dressed around the vent 6. Similarly, where drainage pipes exist it should again be cut and dressed around them.

In addition to providing optimal thermal insulation characteristics, the use of aluminium laminated bubble pack also provides resistance to penetration of rain and other water.
The adapted insulation material and the method of its use is straightforward, efficient and extremely economical and represents a substantial advance in building construction. Although the present invention has been described with respect to one preferred embodiments numerous alternative embodiments are, of course, conceivable within the scope of the invention.
