Abstract
A cavity closer for mounting at a cavity in a cavity wall, the cavity closer having a substantially rigid insulated cavity closer means 8 preferably of non-combustible foam, on one face of which is a heat resistant foil or membrane 9, preferably the face of the closer means 8 which extends across and faces into the cavity. Alternatively the foil or membrane 9 is secured to the face of the closer which abuts the inner face of the inner leaf of the cavity wall, and more preferably also abuts the inner edge of a window or door frame 2 located in the opening. The foil or membrane may be a flexible and may be a piece of flexible metal. A mounting element may be used to hold the cavity closer in place. The wall may be a party wall.
Description
A DEVICE AND ASSEMBLY
The invention relates to a device and assembly, particularly as used at or in a cavity wall construction. This divisional application is based upon GB0709825.4, the entire content of which is incorporated herein by way of reference.
Cavity walls are commonly used in building construction, and usually comprise two leaves, of brickwork or bloclcwork, separated by a cavity. There is a problem associated with such walls, namely loss of heat thcrcthrough.
In modern times, the phenomenon of global warming has lead to measures to try to reduce this wasteful loss of heat, so much so that in the United Kingdom houses which reduce heat loss tbrough such walls by 25% have a tax known as Stamp Duty reduced commensurately when they are sold.
It is an object of this invention to seek to provide a device and an assembly which reduce heat loss.
According to a first aspect the invention provides a device for mounting at a cavity of a cavity wall, comprising a substantially rigid closer means having on one face a heat resistant foil or membrane.
According to a second aspect the invention provides an assembly comprising a cavity wall, a frame of a closure set back a minimum desired distance from an inner face of an outer leaf of the cavity wall and a device for mounting at the cavity having a substantially rigid closer means and a heat resistant foil or membrane on one face of the closer means, the arrangement being such that the device is below a part of the frame which overhangs the cavity.
It will be understood too that the invention extends to a buildin an assembly as hereinbefore described.
Devices and assemblies according to the invention are hereinafter described by way of example with reference to the accompanying drawings, in which the seven Figs. show four embodiments of device and assembly according to the invention.
In the drawings, in which like parts are referred to by like numerals, there is shown an assembly I of a frame 2 such as a door or window frame mounted at a cavity wall 3 having an outer and an inner leaf 4 and 5 respectively, of brickwork or blockwork, separated by a cavity 6.
There is below the frame 2 a device 7 having a substantially rigid non-combustible insulated cavity closer means 8 of foam, on one face of which is a flexible metal or membrane 9 which in Figs. 1 to 5 is on a face of the closer means 8 which extends across and faces into the cavity, In Fig. 6, the foil or membrane 9 is on a face of the closer means 8 which abuts an inner face of the inner leaf 5 of the cavity wall 3, and which lies in substantially the same plane as the inner edge of the frame 2, which itself is set back a distance in the embodiments of 30mm from the inner face of the outer leaf 4 of the cavity wall 3.
The combination of set back of the frame 2 and use of foil 9 reduces heat loss through the wall by at least 25% of the normal t value.
Fig. 7 shows the assembly used at a party wall arrangement.
The closer means 8 is held in a mounting element (10) which bridges the cavity 6, and in some cases the foil 9 is wider than the closer means 8 and can thus be bent to extend round the closer means 8 as shown at 9a and 9b in e.g. Fig. 3. This can enhance prevention of heat loss.
In Fig. 7, there is a closer means 8 which is a fire and acousti proof course).
Various standard elements such as wall ties, peeling strips etc. are not specifically referred to as they form no part of the invention.

An assembly comprising a cavity wall, a frame of a closure set back a minimum desired distance from an inner face of an outer leaf of the cavity wall and a device for mounting at the cavity having a substantially rigid closer means and a heat resistant foil or membrane on one face of the closure means, the arrangement being such that the device is below a part of the frame which overhangs the cavity.
Preferably, the foil or membrane comprises a metal.
Preferably, the foil or membrane is flexible.
Preferably, the closer means comprises a non-combustible foam material.
Preferably, the foil or membrane extends beyond the one face of the closer means.
Preferably, the assembly comprises a mounting element for the device which bridges the cavity and is positioned below the frame.
Preferably, the minimum desired distance is about 30mm back from the inside face of the outer leaf Preferably, the minimum desired distance is 30mm.
Preferably, the frame is a door or window frame or jamb.
Preferably, the foil or membrane extends across the cavity and facing thereinto.
Preferably, the foil or membrane is on a face of the closer means abutting the inner face of the inner leaf of the cavity wall.
Preferably, the foil or membrane on an inner edge of the frame lies substantially in the same plane.
Preferably, the foil or membrane on an inner edge of the frame lies substantially in the same plane as the inner edge of the frame.
Preferably, the cavity wall is a party wall.
The present invention also provides a building including a device and an assembly as defined above.
