Steps

  1. Measure the window glass and frame so you buy a kit big enough to cover the whole opening with a little spare film.

  2. Wipe the frame and trim with a damp cloth and let it dry completely. Tape will not stick to dust, grease or damp paint.

  3. Unroll the film on a flat surface and cut a piece about 2.5 cm (1 inch) wider and taller than the frame.

  4. Peel the backing off the double-sided tape and press it around the whole frame, keeping it straight and close to the edge.

  5. Press the top edge of the film onto the tape first, then gently pull it down and stick the sides and bottom, smoothing as you go.

  6. Run a finger firmly along every taped edge so the film is fully sealed with no lifted corners.

  7. Hold a hairdryer on a high heat setting a few inches from the film and sweep it slowly across the surface until the wrinkles tighten and the film goes clear.

  8. Trim any film hanging past the tape with scissors, then check the edges once more for gaps.

Tips and common mistakes

Keep the hairdryer moving the whole time. Holding it still in one spot can melt a hole in the film.

Apply the tape on a mild day or warm the frame first, because tape sticks poorly to very cold surfaces.

Do not stretch the film hard when sticking it down, or it can pull loose from the tape as it shrinks.

Unplug the hairdryer when you finish and keep the cord away from the window and any water.

Questions

Can I use a normal hairdryer to shrink the film?

Yes. Any hairdryer with a high heat setting works. Use the highest heat and keep the nozzle moving a few inches from the film.

How do I remove the film in spring?

Peel the film off slowly from a top corner and pull the tape away gently. Warm the tape with the hairdryer if it resists, then wipe off any sticky residue.

Will the tape damage my paint or trim?

Most kits use low-tack tape and come off cleanly, but test a small hidden spot first if your trim is freshly painted or delicate.
