Abstract

A window film is made up of polypropylene film having a metallised layer on one side and a light transmissive adhesive on the other. The film may be in tape form.

Description

0 2331269 FULM The invention relates to the use of a film for use in a
wide variety of applications involving heat absorption or insulation or both, e.g. as a solar insert, blind or the like.
Laminates of this type are known. They are used to manufacture clear view solar control blinds, and when modffied by the addition of an adhesive, to bond against the glass, they can be used as solar films. Laminates of this type comprise of layers of transparent plastic film either metalfised, tinted or clear which are bonded together using clear adhesive. The number of layers and the selected plastics will vary according to the circumstances.
One object of the invention is to improve the longwave or room temperature infra red reflection of these types of laminates and thereby to reduce the passage thereof via the surface of the lan-dnate facing the interior of the room.
According to the invention in one aspect there is provided a film for use in an enclosure or the like, comprising a polypropylene film, a metallised layer being preserrt one side of the polypropylene film, a fight transmissive adhesive being present on the other side of the film.
Preferably the density of the metalfised layer is selected so that the polypropylene film has a light transmissivity of about 2% to about 65%, most preferably 15%. The light 2 transmissivity is measured in known way. The metallisation may cover all or only part of the film surface.
The polypropylene is unplasticised, so that it may readily be metallised.
The film may be put to a wide variety of uses within an enclosure such as a sealed glazed unit. The film may be adhered to the inside face of either pane, e.g. a layer of adhesive may be present on the outer face of the polypropylene film, so that it may be adhered to a window. Alternatively the fil:m may be suspended within the cavity of the unit.
In another aspect the film may be suspended in the centre of a double bonded with adhesive to the inner or outer glass surface facing the cavity.
glazing unit or The laminate may also be in tape form, preferably having a longitudinal fold so that the tape may be folded into generally L or U section, as taught in my patent EP 94.9 1005, 1 (Agent's ref: PO 1298EP).
In another aspect, the invention provides a conservatory roof or wall comprising a web of light transmissive plastics, the web having a plurality of parallel passageways, each containing a length of lan-dnate tape in L or U section form.
Investigations have shown that a film of the invention can reflect up to 90% of room temperature infra red, which would normally be lost to the outside, back into the room. As a result the egectiveness as a heat insulating medium is substantially improved.

Claims (6)

1. A film for use in an enclosure, comprising a polypropylene film, a metallised, layer being present one side of the polypropylene filn: a fight transmissive adhesive being present on the other side of the film.
2. A film according to Claim 1, wherein the density of the metallised layer is selected so that the polypropylene fihn has a fight transmissivity of from about 2% to about 65%.
3. A film according to Claim 1 or 2, wherein the polypropylene is unplasticised.
4.
A double or multiple glazed unit having a cavity between the inner and outer panes, and including a film according to any of Claim 1 to 3.
5. A film according to any of Claims 1 to 3, in tape form.
6. A conservatory roof or wall comprising a web of light transmissive plastics, the web having a plurality of parallel passageways, each containing a length of tape according to Claim 5.
A wall according to Claim 6, wherein the tape includes two folds, whereby the tape is of generally U cross-sectional shape, and is received in a passageway of box section with the arms in contact with the opposite side walls of the box section and the bight of the U is not in contact with the intervening wall of the box section.
