Abstract:
Curved, insulating glazing structures (14) and their preparation are disclosed. The glazing structures (14) comprise two rigid outer surfaces (21, 22) (generally glass), and a suspended inner film (23) surface parallel to the outer surfaces (21, 22). The inner film (23) is adhered to the outer surfaces (21, 22) only on its curved edges - its straight edges (16, 16a) being unattached. The inner film (23) is generally heat shrunk in the direction parallel to the straight edges and preferably carries a heat reflective coating.
Abstract:
Conductive micro traces (64) are formed on a coated or uncoated substrate (28) in order to achieve a combination of target optical properties and target electrical capabilities. For the coated substrate, the coating (100) may be formed before or after the conductive micro traces. Thecoating may be designed for providing IR filtering or reductions in reflected light and color shift, while the conductive micro traces may be used for EMI shielding or to provide current-carrying capability, such as when used as heaters. In another embodiment, the conductive micro traces are formed on an uncoated flexible transparent substrate and have a width of less than 25 microns, such that the conductive micro traces are capable of achieving their intended purpose while maintaining a high visible light transmissivity. The conductive micro traces may be formed using various approaches, such as the use of electroplating techniques or the use of inkjet printing techniques.
Abstract:
High-performance heat-reflective films (12) having a metallic silver layer (16) bounded by two dielectric layers (18 and 20) are disclosed. The thickness of the layers (16, 18 and 20) is selected to insure high levels of heat rejection but relatively high levels of light transmission together with a substantial level of color neutrality.
Abstract:
Reflective, metalized plastic films for use in lighting fixture reflectors have improved performance when the plastic film upon which the metalization layer is deposited contains ultraviolet absorber.
Abstract:
Multipane, insulating glazing structures (10) having exceptional thermal insulation performance are provided. The novel multipane structures (10) comprise two substantially parallel rigid glazing sheets (14 and 16) spaced apart by an interior spacer (22) of a low thermal conductivity, closed cell, foamed polymer. In a preferred embodiment, the glazing sheets (12, 14, 16 and 18) are present in a four-pane structure (10) filled with an inert gas and sealed with a gas-impermeable, continuous tape (46) overlaying a curable, high modulus sealant (44). Methods for manufacturing the novel glazing structures (10) are disclosed as well.
Abstract:
Visually transparent, preferably color corrected, infra-red reflecting films (80) are disclosed for solar heat control. The films employ Fabry-Perot sandwich interference filters (12) which are characterized by having two or more transparent layers (16, 16', 16'') of sputter-deposited metal such as silver separated by dielectric spacer layers (18, 18') and optionally boundary layers (20, 22). Methods for producing these materials by sputtering techniques as well as glazing materials (81-84) incorporating these films are disclosed, as well. In preferred embodiments, these films are laminated into glazing structures (81-84).
Abstract:
Structures (10) de vitrage isolant à vitres multiples présentant une efficacité d'isolation thermique exceptionnelle. Les nouvelles structures (10) à vitres multiples comprennent deux feuilles de vitrage (14 et 16) rigides et parallèles, espacées par une pièce d'écartement (22) intérieure en polymère alvéolaire, à cellules fermées, de faible conductivité thermique. Selon un mode de réalisation préféré, les feuilles de vitrage (12, 14, 16 et 18) sont disposées en une structure (10) à quatre vitres remplie d'un gaz inerte, et obturée à l'aide d'un ruban (46) continu imperméable au gaz recouvrant un matériau d'étanchéité (44) durcissable à haut module. Des procédés de fabrication des nouvelles structures (10) de vitrage sont également décrits.
