Best Insulation for Old Homes in Nova Scotia (100+ Year Houses)
The best insulation for old homes in Nova Scotia is closed-cell spray foam combined with targeted air sealing and HRV ventilation. Older homes often have air leakage, moisture intrusion, and uninsulated wall cavities that cause extreme heat loss. Spray foam creates an airtight thermal barrier that significantly reduces heating costs while protecting older structures from moisture damage.
Best Insulation for Old Homes in Nova Scotia — What Really Works
Best insulation for old homes in Nova Scotia is not the same as what works in newer builds. Many heritage and century homes across Halifax, Dartmouth, Bedford, Sackville, and rural communities were built long before modern insulation standards existed.
These homes commonly suffer from:
• Cold drafts
• Ice damming
• Mold and moisture issues
• High heating bills
• Uneven temperatures
Traditional fiberglass batts and blown-in insulation often fail in these structures because they do not stop air leakage — which is the primary cause of heat loss in older Nova Scotia homes.
Why Spray Foam Is the Best Choice for Older Homes
Closed-cell spray foam insulation creates a sealed thermal envelope that:
• Stops uncontrolled air leakage
• Prevents moisture intrusion
• Strengthens aging framing
• Protects against mold growth
• Improves indoor comfort
Spray foam also provides vapor barrier protection — something older homes desperately need due to coastal humidity and winter freeze-thaw cycles.
Where Old Homes Lose the Most Heat
| Area | Impact |
|---|---|
| Rim joists | Major cold drafts |
| Crawl spaces | Moisture & mold |
| Attic slopes | Ice damming |
| Basement walls | Heat loss & dampness |
Quinn Energy targets these critical zones to deliver maximum insulation performance.
Why Blown-In Insulation Often Fails in Old Homes
Blown-in insulation fills cavities but does not seal air movement. Moist air continues to travel through walls, causing:
• Heat loss
• Condensation
• Structural rot
• Reduced insulation lifespan
This is why spray foam dramatically outperforms traditional methods in heritage properties.
