How to seal drafty windows before winter with film and weatherstripping

Stop cold air leaking through your windows and cut heat loss with four cheap layers: shrink film, frame weatherstripping, heavy curtains and a quilted night panel. It suits renters and homeowners with single-pane or old windows. You only need basic tools and a few dollars of materials.

Steps

  1. Check each window for drafts. Hold a lit incense stick or your hand near the frame edges on a windy day and note where air moves.

  2. Clean the glass and frame, then dry them fully. Film and tape stick poorly to dust or moisture.

  3. Cut the shrink film to cover the whole window plus about 2 inches on each side. Press the double-sided tape around the frame.

  4. Stick the film to the tape, then run a hair dryer over it until it pulls tight and wrinkle-free.

  5. Seal the frame perimeter with weatherstripping or foam tape. Fill gaps at the sash, sill and any cracks where air leaks in.

  6. Check that the window still opens and closes if you need it to. Do not block a window you use as an emergency exit.

  7. Hang heavy curtains or cellular shades and close them at sunset every day. Keep them open in daylight for warmth.

  8. Hang a thick quilted panel over the coldest window at night, using a rod or hooks above the frame. Remove it in the morning.

Tips and common mistakes

Layer the methods for the best result: film plus frame sealing plus curtains plus a night quilt.

Shrink film works best on a dry, mild day so the tape bonds well.

Never cover a window you rely on as a fire escape.

Check the film and tape each month and reseal any peeling edges.

Questions

Does window film really save heat?

A sealed film layer creates a still-air gap that acts like rough double glazing. Frost King's own documentation claims up to 35% heat-loss savings through treated windows.

Can I use this in a rented home?

Yes. Shrink film and removable weatherstripping come off without damage, but check your lease before adding hooks for a quilt.

What is the Amish window quilt?

A thick quilted panel hung over the window at night. A wool quilt can rate around R2 to R4, compared with about R1 for single-pane glass.
