Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
97 words
A glazing system comprising a framed pane and a beading strip comprised of two co-extruded hardness grades of a rubber or plastic material, the harder grade of material forming a main body portion of the beading strip which is shaped to fit in the region where the pane adjoins a window frame, so that in use one face of the main body portion is disposed against the pane, whilst an adjacent face of the main body portion is disposed against the window frame, the softer grade of material forming a weather seal which also engages the pane.
Claim 2
Dependent Claim
97 words
A glazing system comprising a framed pane and a beading strip comprised of two co-extruded hardness grades of a rubber or plastic material, the harder grade of material forming a main body portion of the beading strip which is shaped to fit in the region where the pane adjoins a window frame, so that in use one face of the main body portion is disposed against the pane, whilst an adjacent face of the main body portion is disposed against the window frame, the softer grade of material forming a weather seal which also engages the pane.
Claim 3
Dependent Claim
32 words
A glazing system according to claim 1 in which the weather seal is formed with two sealing lips, one lip sealing against the pane, and the other lip sealing against the frame.
Claim 4
Dependent Claim
32 words
A glazing system according to claim 2 in which the region where a said sealing lip engages the pane is spaced from the region where the main body portion engages the pane.

A glazing system according to claim 3 in which the main body portion is retained in place at least partly by an adhesive applied between the main body portion and the frame and pane.
Claim 6
Dependent Claim
40 words
A glazing system according to claim 4 in which the main body portion of the beading strip is made of a first hardness grade of PVC, and the weather seal is made of a second and softer grade of PVC.
Claim 7
Dependent Claim
32 words
A glazing system according to claim 2 in which the region where a said sealing lip engages the frame is spaced from the region where the main body portion engages the frame.
Claim 8
Dependent Claim
34 words
A glazing system according to claim 6 in which the main body portion is retained in place at least partly by an adhesive applied between the main body portion and the frame and pane.
Claim 9
Dependent Claim
40 words
A glazing system according to claim 7 in which the main body portion of the beading strip is made of a first hardness grade of PVC, and the weather seal is made of a second and softer grade of PVC.
Claim 10
Dependent Claim
60 words
A glazing system according to claim 1 in which the main body portion of the beading strip is formed as a solid wedge of material having two faces at right angles to one another which are disposed one against the frame and the other against the pane, the weather seal being attached to another face of the main body portion.
Claim 11
Dependent Claim
25 words
A glazing system according to claim 9 in which the weather seal is attached to the main body portion by means of a narrow spine.
Claim 12
Dependent Claim
105 words
A beading strip for use in a glazing system according to claim 1, the strip being a co-extrusion comprised of two hardness grades of a rubber or plastic material, the harder grade of material forming a main body portion of the beading strip which is shaped to fit in a region where a pane adjoins a window frame, so that in use one face of the main body portion is disposed against the pane, whilst an adjacent face of the main body portion is disposed against the window frame, the softer grade of material serving to form a weather seal which will engage the pane.

Dependent Claim
40 words
A beading strip according to claim 11 in which the weather seal is formed with two sealing lips, one lip serving in use to seal against the pane, and the other lip serving in use to seal against the frame.
Claim 14
Dependent Claim
53 words
A beading strip according to claim 12 in which the weather strip is attached to the main body portion by means of a narrow spine and is so shaped that in use a sealing lip engages the pane at a point spaced from the region where the main body portion engages the pane.
Claim 15
Dependent Claim
40 words
A beading strip according to claim 13 in which the main body portion of the beading strip is made of a first hardness grade of PVC, and the weather seal is made of a second and softer grade of PVC.
Claim 16
Dependent Claim
53 words
A beading strip according to claim 12, in which the weather strip is attached to the main body portion by means of a narrow spine and is so shaped that in use a sealing lip engages the frame at a point spaced from the region where the main body portion engages the frame.
