Abstract
Abstract A glazing seal includes a base which attaches to a supporting structure and a glazing receiver which engages a glazing material to form a seal therewith and is supported on the base such that it can move backwardly and forwardly relative to the base without changing its angle of inclination with respect to the glazing material. This enables the glazing receiver to move with expansions and contractions of the glazing material without impairing the effectiveness of the sealed joint. The seal also contains an internal drainage channel which collects condensation on the glazing material and leakage through the seal and discharges the water so collected to the exterior of the seal. The glazing seal may be used in conjunction with a gutter arrangement including a pair of overlapping gutter members which are elastomeric extrusions capable of being doubled back upon themselves to compensate for a pitch in the gutter or variances in height of the members to which the gutter arrangement is attached.

Claim 6
Dependent Claim
55 words
