Abstract
Abstract A hermetically sealed multiple glazing unit comprises at least one film located between spaced parallel glass panes which are attached to spacing and sealing means constituted by frame portions. The films are attached to the outer frame portions and are stretched when these frame portions are pressed against an intermediate frame portion, by virtue of the profiled confronting surfaces on the frame portions. In another embodiment of the present invention, the multiple glazing unit is not hermetically sealed, and the space between the outer pane and the outermost film is vented through a filter. A silicone coating may be applied to the inner surfaces of the panes and/or to the films to inhibit condensation onto the light-transmitting surfaces. An ultraviolet radiation blocking layer can be provided to protect the film from degradation.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
96 words
A method of stretching at least one film located between two panes of a glazing unit comprising the steps of: (a) providing at least two frame portions to form a full frame; (b) providing the frame portions with mutually confronting profiled surfaces; (c) securing a film to one of the frame portions; (d) assembling the individual frame portions to form the full frame, and (e) pressing-together the frame portions to stretch the film by the coaction of the confronting profiled surface of the second frame portion against the confronting profiled surface of the one frame portion.
Claim 2
Independent Claim
96 words
A method of stretching at least one film located between two panes of a glazing unit comprising the steps of: (a) providing at least two frame portions to form a full frame; (b) providing the frame portions with mutually confronting profiled surfaces; (c) securing a film to one of the frame portions; (d) assembling the individual frame portions to form the full frame, and (e) pressing-together the frame portions to stretch the film by the coaction of the confronting profiled surface of the second frame portion against the confronting profiled surface of the one frame portion.
Claim 3
Dependent Claim
57 words
A method as claimed in claim 1, comprising the further steps of: (f) securing the film to the one frame portion by adhesive means; (g) slipping a peripheral frame onto the one frame portion to hold the film in position before the adhesive sets, and (h) holding the film in an appropriate position until the adhesive sets.
Claim 4
Dependent Claim
34 words
A method as claimed in claim 1 in which the profiled surfaces are so formed as to predetermine the initial stress of the inserted film and thus to predetermine the resonance of the film.
Claim 5
Dependent Claim
38 words
A method as claimed in claim 1 further comprising securing a second film to a respective frame portion and providing a further frame between said films to at least partially absorb the forces derived from the film tension.
Claim 6
Dependent Claim
25 words
A method as claimed in claim 1 in which the frame portions are each constructed as frames in accordance with the size of the panes.
Claim 7
Dependent Claim
19 words
A method as claimed in claim 1 in which the frame portions are constructed from prefabricated profiled bar sections.
Claim 8
Dependent Claim
83 words
A multiple glazing unit comprising (a) at least two panes; (b) a frame having at least two frame portions; (c) mutually confronting profiled surfaces on the frame portions, and (d) at least one film which is secured to one of said frame portions so as to extend between and be substantially parallel to the panes, and said film stretched between the frame portions upon the pulling action of the confronting profiled surfaces on the film when assembling and pressing together the frame portions.
Claim 9
Dependent Claim
83 words
A multiple glazing unit comprising (a) at least two panes; (b) a frame having at least two frame portions; (c) mutually confronting profiled surfaces on the frame portions, and (d) at least one film which is secured to one of said frame portions so as to extend between and be substantially parallel to the panes, and said film stretched between the frame portions upon the pulling action of the confronting profiled surfaces on the film when assembling and pressing together the frame portions.
Claim 10
Dependent Claim
35 words
A multiple glazing unit as claimed in claim 7, in which the films have a coating which is reflective in the infrared range and said coating being sufficiently thin to protect against ultraviolet light discoloration.
Claim 11
Dependent Claim
