Draft-proofing can make Canadian homes more comfortable during winter and may reduce unwanted heat loss. Inspect doors, windows, attic hatches, rim joists, and service penetrations.
Draft-Proofing Checklist
- Check weatherstripping around doors and windows.
- Inspect attic hatches and rim joists.
- Seal suitable service penetrations.
- Look for moisture before sealing.
- Confirm safe ventilation and combustion air.
Before Sealing
Use durable materials suited to each location and follow local codes. Do not block designed ventilation or combustion-air openings.
FAQ
