A kindly client has given me a 6'x4' double-glazed upvc ( two separate panes - one opening ) window for my workshop. As I'm rebuilding the framework I intend to install this window straight into the frame - but it occurred to me that wood tends to shift a bit with expansion. Is this likely to be an issue, or will the frame have enough give in it? There are no fittings with the window - so I assume I'll have to screw through its frame to secure the thing?
Cheers,
Pack between the frame and window with small wedges at your fixing points so you have an at least 5mm gap all round and don't tighten the screws so as to distort the window. Then fill the gap with silicone sealer.
Or use expanding foam, which holds the window securely once it's set. You can then do the fixings without fear of the frame moving about
Absolutely - had a brain fart there.
Know what you mean
No problem, I kind of assumed ( given the thickness of the window frame ) that a combination of squirty foam and sealant would be in order. All I have to do is find some low expansion stuff...it doesn't seem to be as common as the 'big gaps' foam.
One more related query - is it necessary to build an enclosing frame for the window, or is it sufficient to fit the thing flush with the building frame ( I'll bead the exterior to give the lapped panels something to butt up against )?
