Description

Improvements in and relating to Glazina Assemblies The present invention relates to improvements in glazing assemblies, particularly but not exclusively for exterior windows, doors and the like.
Timber frames for windows and glazed doors continue to be popular but, exposed to the weather, they continue to present problems in relation to the sealing between the glazing unit and the timber frame and the prevention of ingress of water into the building.
Conventionally, windows are externally glazed, the glazing unit being inserted into the frame from the outside and held in place against the face of an internal step or rebate in the frame either by putty or, particularly with a multiple pane glazing unit, by a timber glazing bead fixed to the frame by nails or screws. The seal between the glass of the glazing unit, glazing bead and frame is traditionally provided by a setting or non-setting glazing compound and this is known as "wet glazing".
Because of the deleterious effects of weather on the glazing bead and glazing compound, and because the bead is vulnerable to felonious removal, it is becoming common for windows to be internally glazed with the glazing bead provided on the inside, the face of the step against which the glazing unit is held being on the outside.
However, with this arrangement, ingress of rainwater between the frame and glass via the glazing compound then has to be resisted by the internal glazing bead and it is difficult to achieve an effective seal between the glass and external step.
There is also an increasing preference for "dry glazing" using pre-formed flexible sealing strips in place of sealing compound. While effective sealing can be obtained with care in this way with externally glazed sashes, it is not effective for internally glazed sashes because of the difficulty of obtaining a consistent pre-determined compressive force on the external sealing strip.
According to one aspect of the present invention, there is provided a glazing assembly comprising a timber frame made of frame members and having an inner peripheral surface defining an opening, and a glazing unit positioned within the opening, the inner peripheral surface of the frame being formed with a step providing a lateral face against which the glazing unit is applied with the inter-position of a first sealing strip for sealing between the step and the glazing unit, wherein lateral restraining means are provided for holding the glazing unit against the step with the interposition of a second sealing strip for sealing between the lateral restraining means and the glazing unit, locating means being fixed to the peripheral surface of the frame, in a predetermined position relative to the lateral face of the step, for engagement by the lateral restraining means.
The glazing unit may comprise a single pane of glass or may be a multiple pane unit comprising two or more panes of glass which may be spaced apart to provide thermal and/or acoustic insulation and are assembled in a sealed unit.
The first and second sealing strips may be made of a flexible synthetic plastics or a synthetic rubber material such as an ethylene propylene diene monomer (E.P.D.M.). The lateral restraining means and locating means may both be in the form of strips which extend the length of each frame member of the timber frame. They may be extruded, for example of a synthetic plastics material such as PVC (polyvinyl chloride), e.g. PVC-U (unplasticised polyvinyl chloride), or a non-ferrous metal such as aluminium.
It will be appreciated that, by having the locating means fixed in a predetermined position relative to the lateral face of the step, the restraining means will have a predetermined position and can be arranged to apply a predetermined force to the first and second sealing strips to ensure sealing between the glazing unit, the step and the lateral restraining means.
The lateral face of the step may be provided with seal retaining means for retaining the respective first sealing strip in position. The seal retaining means may be in the form of strips extending the length of each frame member and shaped to interengage with a portion of the sealing strip.
The seal retaining means may be made of the same material as the locating means. Preferably the seal retaining means is formed integrally with the locating means, the locating means and seal retaining means then being fixed together in the frame. The first sealing strip is preferably adapted to extend over the join between the lateral face of the frame and the seal retaining means.
Where the seal retaining means and locating means are formed integrally, they may be interconnected by a connecting strip which surrounds the edge of the glazing unit and, in the lower edge of the frame, forms a channel in which water may collect if the sealing is imperfect. The lower member of the frame may be provided with at least one downwardly opening duct extending from this channel and through which any collected water may drain, the duct extending to a part of the frame open to the outside.
Preferably, the locating means comprises at least one protrusion extending from the connecting strip, the protrusion providing a shoulder against which the lateral restraining means abuts to apply a predetermined force to the first and second sealing strips.
The seal retaining means, the locating means and the connecting strip preferably fit entirely within the area of the step in the frame.
In a particularly preferred embodiment, the connecting strip extends entirely between the lateral restraining means and the inner peripheral surface of the frame.
Further features and advantages of the present invention will become apparent from the following description of an embodiment thereof, given by way of example only, with reference to the accompanying drawing, in which the single figure is a section through a member of the frame of an embodiment of glazing assembly according to the present invention.
The glazing assembly shown in the drawing comprises a rectangular frame 1 of timber made of four elongate frame members 2, of which one is shown, and which has an inner peripheral surface 3 defining an opening for a glazing unit 4.
The glazing unit 4 may comprise a single pane of glass or may be a multiple pane unit comprising two (as shown) or more panes of glass spaced apart to provide thermal and/or acoustic insulation, the panes being assembled around spacers and sealed to present a single unit.
The inner peripheral surface 3 of the frame 1 is generally planar and delimited on one side, which is the outside in use, by a step 5 providing a continuous lateral face 6 against which a lateral face of the glazing unit 4 is applied with the interposition of a flexible sealing strip 7 for sealing between the step 5 and the glazing unit 4. As shown, the sealing strip 7 is shaped so as to be compressed between the glazing unit and step to provide the seal.
The sealing strip 7 may be applied directly to face 6 to seal between face 6 and the glazing unit. Alternat-ively, as shown, the face 6 of the step 5 may be provided with seal retaining means 8 for retaining the sealing strip 7 in position during assembly of the glazing unit with the frame.
As shown, the seal retaining means 8 is in the form of a strip, extending the length of each frame member, and is formed with a recess 9 having a constricted opening in which a correspondingly shaped rib 10 on the sealing strip 7 is engaged. The face 6 of the step may be shaped to receive this part of the seal retaining strip 8. Preferably, as shown, the seal retaining strip 8 does not extend above the height of the frame, so that only the timber frame is seen when assembled.
The sealing strip 7 extends over the join between the seal retaining strip 8 and the face 6 of the step to prevent ingress of moisture between the frame and the seal retaining strip.
The glazing unit 4 is held against the sealing strip 7 with a predetermined force by restraining means 11 which may, as shown, also be in the form of a strip, extending the length of each frame member, and which bears against the other face of the glazing unit with the interposition of a second flexible sealing strip 12.
The restraining means 11 is located and held in the correct position relative to the lateral face 6 of the step 5 by engagement with locating means 13 which are fixed in the frame in a predetermined position relative to the lateral face 6 of the step.
As shown, the locating means 13 is in the form of a continuous strip fixed to the surface of the frame and defining an outer lip 13a and an inner channel 13b.
Preferably, as shown, the locating means does not extend beyond the inner peripheral surface 3 of the frame. The restraining strip 11 is provided with a foot 14, one edge portion 14a of which engages in the channel 13b and the other edge portion 14b of which engages inwardly of the outer lip 13a. It will be appreciated that the form of interengagement between the restraining means 11 and the locating means 13 may take a variety of different forms. Advantageously, as with the form shown in the drawings, the arrangement is such that the restraining means 11 is disengageable from the locating means 13 to allow disassembly of the glazing unit. As shown, the restraining means 11 is shaped to engage the sealing strip 12 so as to ensure that the sealing strip cannot easily be removed but such that the sealing strip is removable.Removal of the sealing strip 12 then enables disengagement of the restraining means 11 from the locating means 13.
Preferably, as shown, the seal retaining strip 8 and locating strip 13 are formed integrally as a generally Lshaped member and the same fixing means are used for fixing both strips 8 and 13 in position in the frame. The two strips 8 and 13 are integrally interconnected by a part 15 which surrounds the edge of the glazing unit 4 and this has the advantage that, if, for any reason, the sealing strip 7 or 12 is faulty and permits ingress of water between the seal and glazing unit, the water will collect on the part 15 and will not penetrate into the timber of the frame 1. Drainage means may, as shown, be provided in the lower frame element, comprising one or a plurality of generally vertic-ally extending ducts 16, each opening at its lower end to a part of the frame communicating with the exterior and at its upper end into the part 15.To ensure that no water pene-trates into the timber frame, the or each duct 16 may be lined with a cylindrical element 17 sealed to, or formed integrally with, the part 15.
In use of the above described assembly, seal retaining strips 8 assembled with the sealing strips 7 and the locating strips 13 are positioned in the timber frame members 2 of the frame 1 with the seal retaining strips abutting the lateral face 6 of the step 5, and are fixed in position, e.g. using adhesive, screws or nails. Where the strips 8, 13 are made of aluminium, fixing may be obtained by bending tangs out of part 15 into the wooden frame. The glazing unit is then positioned in the frame using adjust-able spacers to ensure its correct positioning. The restraining strips 11 assembled with the sealing strips 12 are then forced into engagement with the locating means 13 to place both sealing strips 7, 12 under the predetermined required pressure.
To provide the glazing assembly with a timber finish on the inside, a timber bead 18 may be provided which may be fixed to, or releasably engageable with, the restraining means 11. As shown, the restraining means 11 is provided with a projecting rib 19 which is engaged in a slot 20 preformed in the bead 18.
The sealing strips 7 and 12 may, conveniently, be the same as those used in PVC-U and aluminium framed glazing assemblies, and may be moulded of appropriate E.P.D.M.s. The seal retaining, the locating and the restraining means 8, 13, 11 may all be extruded of a synthetic plastics material, such as PVC-U, or a non-ferrous metallic material, such as aluminium.
The above described glazing assembly is, in use, mounted conventionally in an outer frame to form a fixed or opening light for, e.g. a window or door.
