How to Insulate windows for winter
While looking into the best way to insulate our drafty windows this winter (apart from replacing them), I put together this mini-guide of solutions we found so far, including the pros and cons of everything from layered curtains to shrink-wrap film.
1. Rubber Weather Sealing: You can buy strips of self-stick rubber weather sealing at a hardware store or online. Cut long strips down to fit your window dimensions, then peel and stick to the frame to close any gaps and keep out drafts.
2. Window Insulation Film: You can buy window insulation kits from a hardware store or online. Kits usually include plastic shrink film that is applied to the indoor window frame with double-stick tape, then heated with a hair dryer to shrink the film and remove any wrinkles. Check out our tutorial in the link below.
3. Cellular Shades: Cellular Shades insulate while still letting in light through the windows. They can be ordered and custom cut from home and design centers. We found a good set of step-by-step instructions for installation here.
4. Layered Curtains or Insulated Curtains: Use heavy fabrics or layered curtains over the windows to keep out drafts. Or, purchase insulated curtains with built-in thermal backing.
5. Draft Snakes: Draft snakes are fabric tubes placed on a window sill or under a door to prevent cold air from creeping in. You can make one by sewing a tube of fabric to fit the width of your window and filling it with dried rice.
