Weatherproofing Drafty Windows: A Practical Guide
Weatherproofing Drafty Windows: A Practical Guide
Identify Drafts
- Check for air leaks by holding a candle or incense stick near the window frame; flickering smoke indicates drafts.
- Look for visible gaps, cracks, or whistling sounds around frames.
Intermediate Solutions
- Thermal Curtains or Cellular Shades: Add insulation and reduce heat loss.
- Storm Windows: Extra pane creates an insulating air pocket.
- Shrink Film Kits: Applied with a hair dryer to tighten plastic film across window.
Long-Term Fixes
- Replace Old Windows: Modern double- or triple-pane windows drastically improve efficiency.
- Install Energy-Efficient Frames: Vinyl or fiberglass frames resist warping and seal better than wood.
- Professional Air Sealing: Contractors can inject foam or sealant into hidden leaks.
Risks & Considerations
- Moisture Build-Up: Over-sealing can trap condensation, leading to mold. Always keep at least one operable window per room.
- Temporary vs. Permanent: Films and caulks are seasonal; replacements are costly but permanent.
- Energy Savings: The U.S. Department of Energy estimates reducing drafts can save 5–30% annually on heating costs.
Action Plan recommendations
Winters are mild but damp recommend:
- Weatherstripping + caulking for quick fixes.
- Thermal curtains to block cool drafts at night.
- If you plan long-term upgrades, energy-efficient replacements will pay off in reduced utility bills and comfort.
