Claims26
A window sill flashing, comprising:
- a base having a substantially rectangular shape;
- a front flange projecting perpendicularly downward from a front edge of said base;
- at least one side flange extending vertically from a side edge of said base, said at least one side flange including a front surface;
- and
- wherein said window sill flashing made from a sheet of rigid homopolymer vinyl.
A window frame assembly for a building, the window frame assembly comprising:
- an opening formed in a wall portion adapted for receiving a window assembly, the opening including at least two corners located at opposite sides of the opening;
- at least two vacuum formed members located at the at least two corners, the members including a base, and first and second side flanges, with said side flanges extending from opposing side edges of said base, said side flanges including a front surface;
- and
- a cap extending between the at least two vacuum formed members.
A method of forming a window frame assembly for a building, the method including the steps:
- forming an opening in a wall portion for receiving a window assembly, the opening including two opposing corners located at opposite sides of the opening;
- providing a one piece molded plastic member that includes a base, and first and second side flanges, with said side flanges extending from opposing side edges of said base, said side flanges including a front surface, and wherein said first and second side flanges are substantially perpendicular to the base;
- cutting the one piece member to form at least two corner pieces adapted for placement at the two opposing corners formed by the opening, wherein said two corner pieces include a rear wall projecting upwardly from a rear edge of said base;
- attaching the two corner pieces to the two opposing corners, wherein upon attachment a gap is formed between the two corner pieces;
- and
- covering the gap between the two corner pieces.
A window sill flashing, comprising:
- a thin one piece molded plastic member, the member including:
- a rectangular shaped base portion;
- at least one side flange wherein said side flange extends upwardly and substantially perpendicular from a side edge of said base portion and includes a front surface,
- a rear wall extends upwardly and substantially perpendicular from a rear edge of said base portion;
- and
- wherein the base portion is molded to a depth of 1 to 3 ¼ inches with respect to the at least one side flange.
