Tubular weather-stripping made of vinyl is a different option, but it has a tendency to tear and make a difference to the appearance of a window.

When installing replacement sash runners it is essential to take full measurements of the window opening. It is recommended to measure from the top of sash up to the horizontal centerline of the rail that connects them and from the bottom of sash down to the sill. These measurements can be transferred to new runners that will ensure a better fit and operation of the window.

In older structures the gap between the frames and sash is typically larger around the leading edge. It is possible to draught proof by using a self-adhesive V-strips, but it is essential to consider this when cutting and measuring the material.

It should be cut to a square shape and then positioned in a way that the ends are aligned to the angle of the window sill.
