You will need

a small hand-held hair dryer

3. Shrink

Most timber window frames (including doors and skylights) have a flat surface for attaching the tape and membrane without further treatment.

If you have a different type of window frame you may need to vary the method. These variations are described in the instruction sheet. We have a solution for just about every type of window.
