Answers: How can I save money on home heating by finding and fixing heat leaks?

• home heating efficiency
• attic insulation
• air sealing
• window drafts
• door sweeps
• electrical outlet insulation

What it concludes

• To prevent heat loss, insulation and air sealing should be prioritized at the ceiling plane of the attic rather than the roof rafters.
• Window gaps and meeting rails allow significant cold air infiltration and should be sealed with weatherstripping, sash locks, or shrink wrap kits.
• Exterior doors require a door sweep at the bottom to block cold air drafts.
• Electrical outlets on exterior walls let cold air into living spaces and should be sealed with gaskets behind the cover plate.
