What's in the pack?
1 x Pair of Selected Easi Clean Friction Window Hinges
A: First you need to establish the hanging type , do you require a top or side hung hinge? (N. B. These hinges are available in side hung only)
B: Then you need to take your first measurement - this is the actual length of the hinge. You will need to measure the part that fixes to the window frame (not sash), please see the diagram below showing where the hinge length measurements are taken from. Hinges come in the following sizes: 12 or 16 inches long.
C: The second measurement is that of the hinge width i.e. the width of the metal part that fixes to the outer frame. (Almost all window hinges will measure 18mm in width, but with windows that are very old the measurement could be 14mm and if this is the case this hinge will not unfortunately, fit.)
D: The final measurement that you need is the Stack Height, this measurement is the height of the hinge when closed, please see diagram. Stack heights come in two sizes 13mm or 17mm, so even if you are unsure you can usually calculate which is correct because of the 4mm difference.

Cotswold produce the EZ range of easi-clean egress stays that have a clearly identifiable release mechanism to re-position the window for easy cleaning.
The window should have an unobstructed openable area that is at least 0.33m2 and at least 450mm high and 450mm wide (the route through the window may be at an angle rather than straight through). The bottom of the opening area should not be more than 1100mm above the floor.
When the window is closed you can still feel a draught on the side the hinge meets the frame (assuming the window gaskets are in place)
When you close the window the hinges fail to close tightly on the hinge side.
A bent or buckled hinge will make your window almost impossible to open and close.
A broken plastic slider on the hinge will mean the sash will fail to hold when partly open.
Badly corroded hinges will eventually fail and could potentially be very dangerous (we have seen many window sashes that have literally fallen out!). Replace any corroded hinges urgently.
