Description

2350128
IMPROVED FLOOR INSULATION Field of the Invention
The present invention relates to an improved method for insulating floors. It is particularly applicable, but in no way limited, to the insulation of pre-stressed concrete 5 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 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 5 manner, improving the U value of the floor. Summary of the Invention
According to a first aspect of the present invention there is provided a method for insulating the edge of a floor where the floor is mounted along one edge to a wall, the method comprising providing a sheet of thermal insulation material in sheet or roll form and bedding a longitudinal edge of the sheet into a cement joint in the wall that is immediately above one of the rows of bricks or blocks forming the wall that is above the floor and with the sheet of material draping down the outer face of the wall past the level of the floor and at least to the level of the bottom of the row of bricks or blocks immediately below the floor.
Most suitably the insulating material extends from the first or second row substantially down to the level of the top of trench blocks on which the wall is supported.
Preferably the insulating material is a layer of bubble pack laminated on both sides with low emissive aluminium foil. More preferably still this foil is sealed along one longitudinal edge to provide a flange that suitably is of the order of 20 to 30 mm and preferably 25 mm in height to facilitate embedding of the longitudinal edge into the joint. This flange greatly assists the mounting of the upper longitudinal edge in the wall while minimising disruption to the joint.
Although the method could be applied to a single leaf external wall it is clearly preferably applied to the inner leaf of a cavity wall and more normally the inner leaf is of block work while the outer leaf is of brick.
2 Particularly preferably the floor is a slab type floor such as of prestressed concrete and it is particularly preferred that the wall is supported on trench blocks.
A very substantial benefit of the present invention arises from the feasibility of reducing the height of the trench block foundation from what is normally a three block high construction down to a two block high construction. This represents a considerable saving in material costs and labour. Indeed, where the trench blocks are aerated it is possible to obtain a yet further benefit of reducing, or in some cases completely eliminating, the need for any underfloor insulation. These very substantial advantages are achieved through the strategic and highly effective insulation method of the present invention.
According to a second 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 emmissive Aluminium foil and sealed along one longitudinal edge only to provide a flange which is of the order of 20 to 30 mm in height and preferably about 25 mm in height suitable for insertion into a cement joint in a brick or block wall. Brief Description of the Drawinqs
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.
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 aluminiurn foil. In contrast to such thermal insulating sheets as are currently available, however, this 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 aluminiurn 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.
