Pre-formed glazing unit

A pre-formed glazing unit for installation in an opening defined in a structure, the glazing unit comprising:

• a face panel having a periphery enclosing the face panel;
• and
• a mounting flange for attachment to an inward side of the structure around a peripheral edge of the opening in use, the mounting flange being connected to the periphery of the face panel by a connecting wall;
• wherein the connecting wall is integrally formed with the face panel and the mounting flange and extends away from the mounting flange to space the face panel from the mounting flange in an outward direction;
• the periphery of the face panel includes a bottom edge portion, and the connecting wall comprises a bottom panel connected to the bottom edge portion of the periphery;
• and
• the bottom panel is shaped to provide a drip-inducing formation, wherein the mounting flange defines a mounting plane of the unit, and wherein the face panel is inclined with respect to the mounting plane such that a lowermost point of the periphery of the face panel is spaced further from the mounting plane than an uppermost point of the periphery of the face panel in use.

A method for installing a pre-formed glazing unit in an opening in a structure, the method comprising:

• inserting a pre-formed glazing unit, the pre-formed glazing unit comprising:
• a face panel having a periphery enclosing the face panel;
• and
• a mounting flange for attachment to an inward side of the structure around a peripheral edge of the opening in use, the mounting flange being connected to the periphery of the face panel by a connecting wall;
• wherein the connecting wall is integrally formed with the face panel and the mounting flange and extends away from the mounting flange to space the face panel from the mounting flange in an outward direction;
• the periphery of the face panel includes a bottom edge portion and a top edge portion, and the connecting wall comprises a bottom panel connected to the bottom edge portion of the periphery and a top panel connected to the top edge portion of the periphery;
• at least a portion of the top panel is inclined downwardly towards the face panel to deflect water in the outward direction in use;
• the bottom panel is shaped to provide a drip-inducing formation;
• the drip-inducing formation is provided by a feature selected from the group consisting of at least a portion of the bottom panel inclined downwardly towards the face panel, a drip edge, a ridge, and a groove, into the opening to position a mounting flange of the glazing unit against an inward side of the structure around a periphery of the opening, such that at least a part of a face panel of the glazing unit is positioned beyond an outward side of the structure around the periphery;
• and
• attaching the mounting flange to the inward side of the structure.
