PVCU WINDOWS: FRICTION STAYS

 

Window Friction Stays: In a nutshell these are the hinges of the window and depending where the window casement is hinged will depend on the positioning of the friction stays. There are normally two reasons to replace the friction stays:

First Reason For Failure: There are two stays per casement which consist of a stainless steel scissor-type arrangement with a friction plate on each. This is a small plastic piece with a grub screw in the centre. The purpose of this small piece is very important as by turning the grub screw puts more or less pressure on the friction plate which allows the window to be opened slower or faster. It is important that this piece is adjusted correctly as it also allows the window to stay open in whatever position is required. If this is badly adjusted severe damage could occur to the window stays.

Second Reason For Failure: This can be lack of maintenance where the parts have been allowed to corrode and can be avoided by following a simple maintenance schedule.

It is worthwhile remembering that in a lot of properties all of the windows may have been fitted at the same time and it is not uncommon after a period of time for all the windows to show the same problems throughout the house. With this in mind it is more important to consider preventative maintenance which can considerably extend the life of the windows and help prevent having to pay a much larger figure to replace them because parts are obsolete and the only answer is to replace the window.

WINDOW FRICTION STAYS MAINTENANCE: Open the casement and check that the stays are not damaged, bent or broken in any way. Pay particular attention to the small sliding friction plate in each stay (grey or black with a small grub screw). If this or any other part of the stays are broken, seek professional advice from a window company as these will require replacement. Normally if a window stay becomes bent it will not straighten and the only solution is to replace the stays.

Spray, ease and oil all moving parts and open and close the casement to check for operation. The ease of opening the window can be controlled by the two friction plates and by turning the grub screw increases or decreases the amount of resistance when opening and it also controls if the window stays open. Warning: If the friction stay plates are set too light the casement could open at speed and possible damage could occur and make it very difficult to close.

A FURTHER WORD OF WARNING: Double glazed casement windows are extremely heavy and due care and assistance should be sought and used when adjusting operating mechanisms. If in doubt seek professional advice.
