Pvcu Window Hinges
Friction stays are easily changed on pvc windows. Even if the hinges are of a different make they will work perfectly as long as you choose the same length and stack height. We always advise changing both stays at the same time and is why we always sell them in pairs as even if one is ok it will break down in time.
Upvc window hinges are broken into 2 stack heights 13mm - 14mm known as normal or Low Stack height, and 17mm - 16mm height sometimes called high stack type.
Standard hinges or called low stack are the most common used on all types of upvc double glazed window casements
Fire escape or egress hinges have become more popular over the last few years as they provide a means of escape in the event of a fire because they open up to an almost 90 degrees opening. They are only available as side opening and often include an easy clean facility particulary useful for cleaning the outide of the glass. Sometimes called a means of escape hinge.
Restictor hinges operate by immediately providing a restricted opening of approx 100mm when opened. They are quite often called child stays or hinges, as they prevent small persons falling out from high rise situations
Slimline or narrow type hinges are friction hinges that have reduced the width of the hinge part that fits onto the frame part of the window only available as 13mm low stack height. Certain profile manufacturers made their systems to suit these type of hinges only.
