A single piece window frame for holding two spaced apart sheets and having a channel to collect moisture

摘要

Disclosed is a frame member which has a transverse cross sectional profile which includes a primary section and a bridging section projecting substantially orthogonally from a middle section of the primary section so as to leave a portion of the primary section on either side of the bridging section. The bridging section has a secondary section extending substantially orthogonally in one direction away from the bridging section. The secondary section is in an opposed relationship with a portion of the primary section and forms a receiving region in between the primary and secondary sections. The bridging section is split by a longitudinal channel which opens towards the receiving region.
