Description

A BARRIER MEANS
The present invention relates to a barrier means and in particular to an air barrier means for a building component.
Within the construction industry there is an ongoing drive to improve the thermal efficiency of buildings and hence reduce energy consumption and carbon emissions. In the quest for higher efficiencies in this area, regions of weakness have been identified within buildings which lower the airtightness/thermal efficiency of the building as a whole, one such area of weakness being the floor/ceiling at its junction with the walls.
Typical floor/ceiling construction involves the laying of slabs or joists across opposing walls to form a floor or ceiling thereunder or over. In most modern buildings where cavity wall construction is the norm, these slabs or joists are designed to rest on the inner cavity wall. While this is a structurally sound approach to the construction of such elements, it leaves the edge of the floor/ceiling structure exposed to the cavity of the cavity wall. Once construction is complete, cold air is free to travel from the cavity of the cavity wall into any cavities of the floor structure, or between members such as joists. The presence of cold air within the floor structure is in itself enough to reduce the temperature of the floor turning the slabs into cold radiators. However, the problem is magnified by the many punctures which must be made in the floor/ceiling structure to permit plumbing, electrical, and other such services and features to be fitted and to pass through the structure. These punctures permit the cold air now present within the floor structure to travel into the interior spaces of a building creating a further reduction in thermal efficiency.
It is an object of the present invention to obviate or mitigate the problem of cold air travel into the cavity of a floor and/or ceiling structure or between members thereof.
Accordingly, the present invention provides a barrier means for preventing or limiting travel of air into a cavity of a floor or ceiling structure, and/or between members of a floor or ceiling structure, wherein the barrier means is locatable around at least a portion of the floor or ceiling structure at or about the junction between the floor or ceiling structure and the supporting means thereof forming an airtight seal there between.
Advantageously, cold air is prevented from travelling into the cavities of a floor and/or ceiling structure and/or between members thereof, thus preventing the floor and/or ceiling structure acting as a heat sink within a building or a passageway and also preventing cold air from entering the building through features formed in the floor and/or ceiling structure to allow passage of piping, electrical wiring etc. Preferably, the supporting means of the floor or ceiling structure are supporting walls.

In the drawings, there is shown a barrier apparatus indicated generally by the reference numeral 1 for preventing or limiting travel of air into a cavity of a floor structure 2.
The barrier apparatus is located around an end 3 of the floor structure 2 at or about the junction between the floor structure 2 and the supporting walls 4 thereof, forming an airtight seal there between.
Cold air is prevented from travelling into the cavities 6 of a floor structure 2, thus preventing the floor structure 2 acting as a heat sink within a building or a passageway. The cold air is also prevented from entering the building through features formed in the floor structure 2 to allow passage of piping, electrical wiring etc. The barrier apparatus 1 has an airtight membrane 7 and a membrane support member 8. The membrane support member 8 is a stiff member to which the airtight membrane 7 is attached, retaining the airtight membrane 7 in the desired shape and providing support thereto.

The airtight membrane is attached to the outer exterior channel surface 10 and extends beyond the membrane support member 8 via an extension portions 11.
The membrane support member 8 is configured to receive at least an end 3 of a floor structure 2, the floor structure having a substantially right angled corner 12 which is placed into the interior right angle 13 of the elongate L-shaped section 7. The floor structure 2 has an end portion 3 which extends substantially vertically between an upper floor forming surface 14 of the floor structure 2 and a lower floor forming surface 15 of the floor structure 2.
The portion of wall 4 formed for receiving a floor structure 2 has a gap 16 formed therein and the membrane support member 8 is formed for insertion into this gap 16. A first portion 17 of the membrane support member 8 is attached to the portion of the wall 18 formed for receiving a floor structure 2, or is trappable between said portion of the wall 18 and the floor structure 2. A second portion 19 of the membrane support member 8 extends across the gap 16.
The portions of the airtight membrane 7 that extend beyond the membrane support member 8 are attachable to an inward facing wall 20 into which the floor structure 2 received.
