Definitions

  • the present invention relates to glazing units and to glazed structures comprising such glazing units.
  • low emissivity coating is used herein to refer to a coating which has an emissivity of 0.2 or less calculated from measured infra red reflectance at near normal incidence in accordance with British Standard 6993.
  • Such coatings can be soft, when applied by sputtering, or hard when applied pyrolitically or by magnetron. Soft coatings tend not to cope well with handling.
  • Solar control coatings are also known. These coatings apply a very thin reflective layer to a surface of a glass pane to reflect visible sunlight and are generally used to reduce glare and light levels in buildings.
  • Self-cleaning coatings are also known. To date, these are of two types, either hydrophilic or silicone based.
  • a glazing unit comprising two opposed spaced panes, a first pane and a second pane, with spacing means between the panes, wherein a first pane has a low emissivity coating and solar control coating on its face towards the other pane, a self-cleaning coating on the face of the first pane away from the other pane and in which the first pane is body tinted.
  • this structure provides an enhanced glazing unit .
  • the low emissivity and solar control coating may be provided as two separate coatings.
  • the body tint is a green body tint.
  • the self-cleaning coating is non-hydrophilic.
  • the self-cleaning coating is a silicone-based coating.
  • the use of a silicone self-cleaning layer is especially beneficial as the silicone used during installation does not affect it as it would a hydrophilic coating.
  • the second pane has a low emissivity coating on its face towards the other pane.
  • the second pane is a clear glass.
  • the first pane is a 4mm pane.
  • the second pane is a 4mm pane.

  • the first pane is an exterior pane and the second pane is an interior pane.
  • the glazing unit has a U-value of less than or equal to 1.2 W/m 2 K.
  • the glazing unit is suitable for a conservatory glazing.
  • the glazing unit is suitable for an overhead glazing.
  • a glazing pane For a glazing pane to have a coating it need not be applied directly to the glass surface. Intermediate layers may be used as is known to those skilled in the art. Further it may be a single or multi-layer coating.

Abstract

L'invention concerne une unité de vitrage (2) qui comprend deux panneaux (4, 6) espacés opposés, un premier panneau (4) et un second panneau (6), et comporte des moyens d'espacement (8, 10) entre les panneaux. Le premier panneau (4) présente un revêtement à faible émissivité et un revêtement (14) solaire sur la face dirigée vers l'autre panneau, un revêtement (18) autonettoyant sur la face du premier panneau éloignée de l'autre panneau, et le corps du premier panneau est teinté.
