Abstract
In a preferred embodiment, a method of replacing an existing window of the type having an existing fixed metal frame mounted in an existing window opening, the method including: removing elements of the existing window, except the existing fixed metal frame, while leaving the existing fixed metal frame in place and without rebuilding the existing window opening; providing a replacement window having a glazed monolithic frame member; and attaching the monolithic frame member to the existing metal frame by inserting fasteners through the monolithic frame member directly into the existing fixed metal frame.
Claims14
A method of replacing an existing window of the type having an existing fixed metal frame mounted in an existing window opening, comprising:
- (a) removing elements of said existing window, except said existing fixed metal frame, while leaving said existing fixed metal frame in place and without rebuilding said existing window opening, including the step of removing an existing glass pane sealed directly to said existing fixed metal frame;
- (b) providing a replacement window having a monolithic frame member;
- and
- (c) attaching said monolithic frame member to said existing metal frame by inserting fasteners through said monolithic frame member directly into said existing fixed metal frame.
A replacement window for an existing window of the type having an existing fixed metal frame mounted in an existing window opening, comprising:
- (a) a monolithic frame member insertable in said window opening against said existing fixed metal frame after elements of said existing window have been removed, except said existing fixed metal frame, while said existing fixed metal frame has been left in place and without rebuilding said existing window opening;
- and
- (b) fastening means for insertion through said monolithic frame member directly into said existing fixed metal frame to secure said monolithic frame member in said window opening;
- wherein:
- said existing fixed metal frame includes a cross-wisely extending rear flange member, a cross-wisely extending front flange member, and a forwardly and rearwardly extending intermediate flange member extending between and joining opposite ends of said rear and front flange members, and said monolithic frame comprises:
- (c) a rearwardly extending rear flange member, a forwardly extending front flange member, and a cross-wisely extending intermediate flange member extending between and joining said rear and front flange members;
- and
- (d) said flange members of said monolithic frame being arranged such that, when said replacement window is inserted in said existing window opening, said intermediate flange member of said monolithic frame will abut said front flange member of said existing fixed metal frame and said rear flange member of said monolithic frame will be parallely disposed with said intermediate flange member of said existing fixed metal frame for the fastening therebetween of said fastening means.
A method of replacing an existing window of the type having an existing fixed metal frame mounted in an existing window opening, comprising:
- (a) removing elements of said existing window, except said existing fixed metal frame, while leaving said existing fixed metal frame in place and without rebuilding said existing window opening, including the step of removing an operating sash having hinges attached directly to said existing fixed metal frame;
- (b) providing a replacement window having a monolithic frame member;
- and
- (c) attaching said monolithic frame member to said existing metal frame by inserting fasteners through said monolithic frame member directly into said existing fixed metal frame.
A method of replacing an existing window of the type having an existing fixed metal frame mounted in an existing window opening, comprising:
- (a) removing elements of said existing window, except said existing fixed metal frame, while leaving said existing fixed metal frame in place and without rebuilding said existing window opening;
- (b) providing a replacement window having a monolithic frame member;
- (c) attaching said monolithic frame member to said existing metal frame by inserting fasteners through said monolithic frame member directly into said existing fixed metal frame
- (d) forming two, generally vertically aligned, closely spaced, upper and lower holes through said monolithic frame member;
- (e) injecting a curable material into said upper hole to partially fill a space defined between said monolithic frame member and said existing fixed metal frame;
- (f) inserting one of said fasteners through said lower hole and tightening said one of said fasteners a desired degree;
- and
- (g) permitting said curable material to cure, so as to form a resilient spacer in said space defined between said monolithic frame member and said existing fixed metal frame.
