Key Takeaways
- Seal gaps with weatherstripping or caulk for instant insulation.
- Use window film to create an airtight barrier without replacement.
- Draft stoppers block cold air from sneaking under sashes.
- Heavy curtains add an extra layer of insulation.
1. Apply Weatherstripping
Weatherstripping is a cost-effective way to seal gaps around movable window parts. Options include:
- V-seal tape (spring-metal or plastic) for sash edges.
- Adhesive foam tape for irregular gaps.
- Felt strips for low-traffic windows.
Duck Brand’s self-adhesive rubber weatherstrip ($6.99 on Amazon) is durable and easy to install. For older windows, combine with wood-safe cleaners to prep surfaces.
2. Install Window Insulation Film
Shrink film kits (like Duck Max Strength, $8.49) create a temporary second pane. Steps:
- Clean the frame and apply double-sided tape.
- Stretch the film over the window.
- Use a hairdryer to shrink wrinkles for a tight seal.
This reduces heat loss by up to 30% and lasts all winter.
3. Use Draft Stoppers
Fabric draft snakes block air leaking under sashes. The Home Intuition stopper ($14.95) fits 36″ windows and has a fleece lining. For a DIY version:
- Fill a tube sock with rice or polyester stuffing.
- Place it along the sill.
4. Caulk Gaps
Inspect frames for cracked caulk. Use rope caulk (Frost King, $6.05) for small gaps or silicone caulk for larger ones. Focus on:
- Window perimeters.
- Where the frame meets the wall.
5. Hang Thermal Curtains
Heavy curtains with thermal backing trap air. Honeycomb shades are even more efficient, reducing drafts by 40%. Pair with a hard-floor vacuum to keep dust from settling.
Comparison Table: Draft-Stopping Methods
| Method | Cost | Effectiveness | Difficulty |
|---|---|---|---|
| Weatherstripping | $5–$20 | High | Easy |
| Window Film | $8–$15 | Medium-High | Moderate |
| Draft Stoppers | $10–$25 | Medium | Very Easy |
6. Add Bubble Wrap Insulation
For a quirky but effective fix, spray water on windows and press bubble wrap against the glass. This creates air pockets that reduce heat transfer. Best for basements or infrequently used rooms.
7. Upgrade to Storm Windows
While pricier (from $125), storm windows cut energy loss by 30%. Larson’s aluminum models are durable and fit over existing frames.
