Replacing hardwood timber framed window hinges

[foxhole]

My double glazed windows are all beginning to sag with tired hinges, anyone now a reliable source of replacements, are there different grades/quality according to frame weight or all similar? I have a variety of window sizes but same hinge type seem to have been used throughout.

Hi Fox]

send a few pics and size of hinges

My hinges are similar in style and size to these
http://www.screwfix.com/p/friction-hinge-top-hung-400-x-17mm-pack-of-2/90866

While the windows are all around 500mm wide they vary from 600mm to 1200mm in height.

DG supplyline are down your way, we use them loads mainly mail order, very helpful people

Trouble with top openers they always sag or drop with gravity, it could be the hinges are fine (unless they have obvious wear), its possible they've just crept down on the fixing screws screwed into the sides of the sash, i assume they are catching across the bottom, very common with top hungs?

These guys are pretty good too, i believe they even come and do the work also if you need that

They are all secure but need to lift slightly to align catch to close on some.

I may have wrongly assumed they were top openers, probably due to your link, side opener friction hinges have an extra element in them to give strength, when sourcing make sure you specify which you need, also don't forget the 'stack height', this is the hinge thickness when fully closed, usually 13 or 17mm, ideally you need to shut your window as much as possible and measure the gap between the frame and sash, this should be close enough to tell you which you need
