I'm just about to attempt to fit a couple of uPVC windows but I'm getting conflicting advice as to how to fit the cill.
Which way is best?
I'm thinking of:
- Siliconing the upstand
- Fixing the cill to the frame with screws through the bottom of the cill into the underside of the frame
- Siliconing the left and right edges of the frame where it meets the cill
- Siliconing or foaming the cill into the opening
So there'd be no mechanical fixing through the frame and cill into the brickwork.
Is that OK?
Thanks!
