At least a part of the surface of the moulding is covered (a) by a film (2) or layer of plastics material e.g. PVC, or resin coated substrate and (b) by a coating of intumescent material, e.g. intumescent varnish. <IMAGE>
Description
MOULDING
This invention relates to mouldings, especially for use in the construction of glazed fire resisting doors.
Timber is a desirable structural material because it can give a naturally decorative effect quite economically and it is clearly advantageous if a methodscan be found. of using timber while providing means for rendering a glazed panel much more resistant to fire spreading than would normally be the case with such a material.
Glazing strips made of non-combustible and poor heatconducting material are used for fixing fire resistant glass into timber or other frames which can be charred or otherwise depleted by fire and strips are used which enable a timber-framed window, glazed screen or glass door for example, to have good overall resistance against the spread of fire from one side to the other. Such strips also have a coating of intumescent paint, the swelling or intumescence occurring on heating during a fire.
The disadvantage of such strips is that their visual appearance is not very good and their technical performance is not as good as other glazing strips.
We have now devised mouldings of improved visual appearance and technical performance and according to this invention a moulding having a channel or rebate and suitable for use in the construction of fire resisting doors is one which is made of substantially non-combustible material and wherein at least part of the surface of the moulding is covered (a) by a film or layer of plastics material or resin coated substrate and (b) by a coating of intumescent material.
The moulding will usually be provided with a channel designed to receive a panel or preferably a sheet of glass.
On some occasions the moulding will have more than one channel, e.g. a pair of substantially parallel channels so that for example a double glazed window, door etc. can be provided. The moulding may alternatively be provided with a rebate adapted to receive for example a sheet of glass secured by putty or adhesive cement, e.g. clay modified sodium silicate. The latter can be applied to the entire surround or only to areas, e.g. the top channel, where stresses will be more severe.
It is preferred that the moulding is used for the construction of glazed panels, doors, windows etc. but the moulding can be used for the construction of other fire resistant panels, walls etc. wherein materials other than glass are received in the channel or rebate.
The moulding must be made of substantially noncombustible material. Such materials include for example fibre reinforced materials; for example fibre reinforced calcium silicate, fibre reinforced gypsum; glass reinforced gypsum; sodium silicate bonded vermiculite; cement bonded wood particles or gypsum bonded wood particles.
These mouldings are made for example by moulding or by machining from boards or by casting by extrusion
The film or layer of plastics material or resin coated substrate which covers at least part of the surface of the moulding can be for example a vinyl resin such as polyvinyl chloride (PVC) film, polyethylene, polypropylene, polystyrene, ethylene-vinyl acetate copolymers, acrylic resins. Either thermoplastic or thermosetting plastics could be used.
As an alternative to plastics one may use a resin coated substrate, especially resin-impregnated paper, preferably impregnated printed paper. Suitable resins include acid catalysed lacquers. However, cellulose based resins or lacquers should be avoided.
The film or layer can be of a smooth or textured colour or can be simulated wood grain, e.g. teak, mahogany, elm or oak.
The thickness of the film or layer can vary but is usually between 0.05 and 0.15mm, for example about 0.lmm.
The coating of intumescent material is preferably a coating of intumescent paint or a coating of clear intumescent varnish, for example Copon 4000. The thickness of the coating of intumescent material can vary, but is preferably between 0.1 and 0.5mm, for example about 0.3mm.
There are various ways of covering at least part of the surface of the moulding with (a) plastics material or resin coated substrate film or layer and with (b) intumescent material. The moulding may be first printed with intumescent paint and the film or layer of plastics material or resin coated substrate thereafter applied to the painted moulding. Preferably the film or layer is bonded to the moulding by the use of an adhesive but if the film or layer is relatively stiff it could be sprung onto the moulding, parts of the film or layer gripping the sides of the channel(s) and sides of the moulding.
In the preferred embodiment when the film or layer is bonded to the moulding by use of an adhesive, suitable adhesives include hot melt polyurethane or other thermosetting or curing adhesives, for example epoxy or phenolic resins.
The film or layer can be wrapped onto the moulding by the use of a profile wrapping technique.
In the alternative embodiment when the film or layer is applied to the moulding before the application of intumescent material, the application of the film or layer can be as described above. After this has been done a coating of intumescent material is applied and the material should be clear intumescent varnish rather than paint so that the film or coating often with the simulated wood grain is still visible.
It is not necessary for the whole surface of the moulding to be covered by the film or layer of plastics or resin but usually all those parts which are visible when the moulding is in use will be covered by the film or layer.
Likewise not all the surface of the moulding need be covered by intumescent material, but at least those parts should be covered where, should there be a fire, the swelling of the intumescent material is necessary or desirable to retard or prevent the spreading of the fire. Such parts should preferably include the base of the channel or rebate.
The advantage of the mouldings of this invention compared with previously used mouldings are that they have a much better visual appearance and any imperfections in the moulding are hidden. Also they are easy to handle and less prone to breakage or damage. If the film or layer of plastics material or resin coated substrate is turned at least partially into the channel(s) the glass or other panel is held steady and rattle is prevented.
A moulding in accordance with this invention is now described with reference to the accompanying drawing which shows a cross-section of the moulding.
Referring to the drawing, the moulding 1 has a channel 2 of a suitable size to receive a sheet of glass. The moulding was made of fibre reinforced calcium silicate. The surface of the channel 2 was first primed with dilute polyvinyl acetate emulsion and adhesive was applied to a PVC film 3. This film 3 was then fixed to the moulding 1 by means of a profile wrapping technique. Heat curing was then applied to cure the adhesive and clear intumescent varnish was applied to the base of the coated channel 2. It can be seen that most of the moulding 1 is covered; only the base and lower parts of the side walls of the channel 2 are uncovered. The upper portions of the side walls of the channel 2 are covered with film and this also serves to provide a tight fit when the glass is located in the channel 2.
