Baypole Screws

[Discoeye]

Can anybody recommend a baypole screw length for fixing a upvc cill to the window frame.

Thanks all.

Will depend on the window system and whether there is reinforcement in the frame. Get an installation drawing or guide from the manufacturer. Obviously don't want a screw long enough to cause any problems.

 

Fixing the cill to the window frame prior to fitting the combination. I screwed my cill down to masonry (using 7.5mm X 122mm Frame Fixing screws). But that's the recommended approach for my window system (Residence 9)

Thank you . Another daft question is there a sweet spot for frame fixings through the window frame i.e: front edge ,back edge or centre of frame.

Centre of the frame, bead of decent sealant on the lip of the cill only, then screw down but not so much that you distort the cill base.

Thank you, so fixings in the centre for securing the window also.
