The host tests five different DIY methods for insulating drafty windows—bottom foam seal, seal tape, backer rod, window film, and thermal curtains—evaluating them by price, installation, looks, usability, and thermal performance using a thermal camera.
From the video
Answers: What is the best way to insulate drafty windows?
- DIY window insulation
- Thermal imaging window draft test
- Weatherstripping windows
- Window shrink film kits
- Thermal curtains for draft prevention
What it concludes
- Bottom foam seal and seal tape are inexpensive and easy to install, but seal tape completely blocks window usability and strips paint upon removal.
- Bubble wrap provides a cheap option but performs poorly as thermal insulation and obstructs window usability and looks.
- Window film stops drafts well and retains a clear view, but can damage paint upon removal and hinders window usability.
- Thermal curtains are the top-rated overall solution, offering great looks, easy installation, and strong thermal performance with a 7 to 13 degree temperature difference.
