Abstract
Abstract A silicone glazing system for supporting and retaining a glass pane wherein the window frame is lined with a spacer rod composed of a heat cured vulcanizable silicone rubber composition of a Durometer A Hardness of at least 30, and the window pane is placed and rested against the spacer rod. There is applied a room temperature vulcanizable silicone rubber sealant over the exposed areas of the spacer rods so as to join and bind the window pane to the window frame.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
254 words
A window pane construction in which the window pane is substantially flush with the exterior wall of a building and in which there is no external abutment lip on the external surface of said window pane comprising a four-sided window frame which has supporting sides extending around said opening and perpendicular to the opening in said window frame and lip sides which are perpendicular to said supporting sides and extending from the interior from said supporting sides to the edge of the building exterior, spacer rods formed from a heat vulcanizable silicone rubber of at least 30 Durometer Hardness extending along all four of said supporting sides of said window frame and extending along all four of said lip sides, but such that said spacer rods on said lip sides do not cover all of the surfaces of said lip sides which are perpendicular to the opening in said window frame so as to leave a toe surface on said lip sides, said toe surface extending on all sides of said window frame and external-most from the interior of the building, a window pane resting on and against and supported by said spacer rods, and a layer of a room temperature vulcanizable silicone rubber sealant applied over the exposed external surfaces of said spacer rods and extending from the toe surface on said lip sides to the edge of said window pane such that when said sealant has cured, the cured sealant maintains said window pane in place in conjunction with said spacer rods.
Claim 2
Dependent Claim
254 words
A window pane construction in which the window pane is substantially flush with the exterior wall of a building and in which there is no external abutment lip on the external surface of said window pane comprising a four-sided window frame which has supporting sides extending around said opening and perpendicular to the opening in said window frame and lip sides which are perpendicular to said supporting sides and extending from the interior from said supporting sides to the edge of the building exterior, spacer rods formed from a heat vulcanizable silicone rubber of at least 30 Durometer Hardness extending along all four of said supporting sides of said window frame and extending along all four of said lip sides, but such that said spacer rods on said lip sides do not cover all of the surfaces of said lip sides which are perpendicular to the opening in said window frame so as to leave a toe surface on said lip sides, said toe surface extending on all sides of said window frame and external-most from the interior of the building, a window pane resting on and against and supported by said spacer rods, and a layer of a room temperature vulcanizable silicone rubber sealant applied over the exposed external surfaces of said spacer rods and extending from the toe surface on said lip sides to the edge of said window pane such that when said sealant has cured, the cured sealant maintains said window pane in place in conjunction with said spacer rods.
Claim 3
Dependent Claim
26 words
The window frame construction of claim 1 wherein said spacer rods are at least one-eighth of an inch thick and an eighth of an inch wide.
Claim 4
Dependent Claim
29 words
The window pane construction of claim 2 wherein said layer of silicone sealant is applied at least one-eighth of an inch thick and an eighth of an inch wide.
Claim 5
Dependent Claim
22 words
The window pane construction of claim 1 wherein said spacer rods have a Durometer Hardness in the range of 40 to 60.
Claim 6
Dependent Claim
47 words
The window pane construction of claim 4 wherein said spacer rods are present in more than one integral section along a particular side of said window frame and such that there is one section along said supporting sides and another separate section resting against said lip sides.
Claim 7
Dependent Claim
34 words
The window pane construction of claim 2 wherein said spacer rods extending along a particular side of the window frame and resting along said supporting sides and lip sides are constructed in one section.
Claim 8
Dependent Claim
71 words
The window pane construction of claim 5 wherein in the section of the spacer rod which is located below the window pane and on which the window pane rests there are sections cut out therefrom to form cavities and in which cavities there are located Neoprene setting blocks having a Durometer A Hardness in the range of 75 - 90 on which most of the weight of said window pane rests.
Claim 9
Dependent Claim
237 words
A process for installing a window pane substantially flush with the external walls of a building and in which there is no external abutment lip on the external surface of said window frame wherein there is present a four-sided window frame which has supporting sides extending around said opening and perpendicular to the opening in said window frame and lip sides which are perpendicular to said supporting sides and extending from the interior from said supporting sides to the edge of the building exterior comprising (a) placing along all four of said supporting sides and said lip sides spacer rods formed from a heat vulcanizable silicone rubber having a Durometer Hardness of at least 30, but such that said spacer rods on said lip sides do not cover all of the surface of said lip sides so as to leave a toe surface on said lip sides said toe surface extending on all sides of said window frame and external-most from the interior of the building; (b) resting on and against said spacer rods a window pane; and (c) applying a layer of room temperature vulcanizable silicone rubber sealant over the exposed external surface of said spacer rods and extending from the toe surface on said lip sides to the edge of said window pane such that when said sealant has cured, the cured sealant maintains said window frame in place in conjunction with said spacer rods.
Claim 10
Dependent Claim
237 words
A process for installing a window pane substantially flush with the external walls of a building and in which there is no external abutment lip on the external surface of said window frame wherein there is present a four-sided window frame which has supporting sides extending around said opening and perpendicular to the opening in said window frame and lip sides which are perpendicular to said supporting sides and extending from the interior from said supporting sides to the edge of the building exterior comprising (a) placing along all four of said supporting sides and said lip sides spacer rods formed from a heat vulcanizable silicone rubber having a Durometer Hardness of at least 30, but such that said spacer rods on said lip sides do not cover all of the surface of said lip sides so as to leave a toe surface on said lip sides said toe surface extending on all sides of said window frame and external-most from the interior of the building; (b) resting on and against said spacer rods a window pane; and (c) applying a layer of room temperature vulcanizable silicone rubber sealant over the exposed external surface of said spacer rods and extending from the toe surface on said lip sides to the edge of said window pane such that when said sealant has cured, the cured sealant maintains said window frame in place in conjunction with said spacer rods.
Claim 11
Dependent Claim
23 words
The process of claim 8 wherein said spacer rod is at least one-eighth of an inch thick and one-eighth of an inch wide.
Claim 12
Dependent Claim
