We headed out an hours drive from Adelaide for this job. We removed 4 sections of a window frame (1 awning and 3 fixed panels).
added cowdroy top hung track systems on the inside and outside of the frame. Prior to coming out we had made a pair of doors and a pair of flydoors (in meranti to match).
added flydoors to external track and glass doors to internal tracking. Added rubber seals around doorstop of the glass doors for good weathersealing. Glass doors were double glazed.
