For Optimal Insulation Performance, Air Sealing is Critical
Effective air sealing is critical to insulation performance.
Tips for Sealing Air Leaks:
- Hire an energy assessor or other weatherization expert to test your home for air tightness.
- Caulk and weatherstrip doors and windows that leak air.
- Caulk and seal air leaks where plumbing, ducting, or electrical wiring comes through walls, floors, and ceilings.
- Install foam gaskets behind outlet and switch plates on walls.
- Inspect dirty spots on any visual insulation for air leaks and mold. Seal leaks with low-expansion spray foam made for this purpose and install house flashing if needed.
- Look for dirty spots on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists, and caulk them.
- Replace single-pane windows with more efficient double-pane low- emissivity windows. See the Windows section for more information.
- Use foam sealant on larger gaps around windows, baseboards, and other places where air may leak out.
- Check your dryer vent to be sure it is not blocked. This will save energy and may prevent a fire.
- Replace exterior door bottoms and thresholds with ones that have pliable sealing gaskets.
- Keep the fireplace flue damper tightly closed when not in use.
- Seal air leaks around fireplace chimneys, furnaces, and gas-fired water heater vents with fire-resistant materials such as sheet metal or sheetrock and furnace cement caulk.
