Crawl Space Insulation: Is Your Home Losing Heat Below?

# Crawl Space Insulation: Is Your Home Losing Heat Below?

Many Ottawa homes have crawl spaces that are poorly insulated or not insulated at all. This leads to cold floors, drafts, and wasted energy.

Symptoms of crawl space issues include floors that feel cold even with heat running, drafts near floor level, ice dams that seem excessive, and high heating bills.

Two approaches to crawl space insulation exist. The traditional method insulates between floor joists, keeping crawl space outside the thermal envelope. The preferred method encapsulates the crawl space, bringing it inside the thermal envelope.

Encapsulation includes sealing vents, adding vapor barrier on floor and walls, insulating foundation walls, and conditioning the space with minimal heat.

Benefits include warmer floors, reduced heating costs, better humidity control, and protection against frozen pipes.

Costs in Ottawa run $3,000-$8,000 for encapsulation depending on size and access.

Moisture control is critical. Ottawa crawl spaces are prone to moisture intrusion. Address water problems before insulating.

Properly insulated crawl space can reduce heating costs 15-20% while dramatically improving comfort.
