What is a slimline window hinge?
These hinges are narrower than the standard hinges you find on most double glazed windows. The overall width of the track is only 15mm as opposed to the 18mm size you get with standard hinges.
Can I use the standard hinge as a replacement?
You might be able to do that but in most cases there is a channel that the hinge fits into so the 18mm wide standard hinge would not fit.
Where are slimline hinges usually fitted?
A lot of the older aluminium frames particularly and some older upvc windows will have used them. It is increasingly rare to find them these days.
Are these hinges handed?
You don't need to worry about this when purchasing them as they come as a pair. When you fit them you must open the hinge in the direction of the arrow and fit them accordingly to the respective side of the window.
