If you have old, single-pane windows but can't afford a $10,000 replacement, there's a surprisingly effective 'shipping' solution: bubble wrap. Yes, really.
The air bubbles in the wrap act as a series of miniature 'double glazing' layers. Spray a fine mist of water on your clean window, press the flat side of the bubble wrap against the glass, and it will stay there all winter. It still lets in plenty of light but creates a thermal barrier that can reduce heat loss through the glass by up to 50%. It's not the most 'architectural' look, but for a spare room, a basement, or a workshop, it's a game-changer.
It's cheap, removable, and reusable. In the spring, just peel it off and save it for next year. No tape, no mess, no glue. It's the practical 'functional over fashion' energy hack. If you're struggling with high heating bills in an old apartment or home, this tip might just be the best $5 you ever spend. Give it a try—your toes will thank you!
