It is best to measure from the top of the sash up to the horizontal line on the rail of the meeting and from the bottom of sash down to the sill. These measurements can be transferred to the new runners, which will ensure a proper fitting and better operation of the window.
In older structures the gap between frame and sash is typically larger around the leading edge. It can be draught-proofed by using a strip of V-strip which is self-adhesive. However it is crucial to take this into consideration when measuring and cutting material.
A strip must be cut to the height of the sash. There should be an additional inch on each side for movement.
