How much does insulation cost in New Brunswick?
Insulation costs in NB vary by type and scope: attic blown-in cellulose runs $1,200-$5,500 to reach R-60 code targets, spray foam insulation costs $2,500-$12,000 depending on area and foam type, batt insulation for open walls runs $1,000-$5,000, and basement insulation costs $2,000-$9,000. NB Power rebates and the federal Greener Homes Grant can offset 30-50% of project costs for qualifying upgrades.
What R-value do I need for my New Brunswick home?
The NB Building Code recommends R-60 for attics, R-24 for above-grade walls, R-20 for below-grade foundation walls, and R-10 for under-slab insulation. Most existing NB homes have attic R-values of only R-20 to R-30. Northern NB communities (Edmundston, Grand Falls, Campbellton) fall in Climate Zone 7A where even higher R-values are recommended.
Is spray foam insulation worth the cost in NB?
For most NB homes, spray foam delivers the best long-term value. Closed-cell spray foam provides R-6.5 per inch while also serving as an air barrier and vapour retarder. In NB's Maritime climate with 100-120 freeze-thaw cycles annually, spray foam seals every gap and crack, eliminating convective heat loss that batt insulation cannot prevent. Typical payback through energy savings is 5-8 years.
Are there rebates for insulation upgrades in New Brunswick?
Yes. NB Power offers energy efficiency rebates for qualifying insulation upgrades when supported by a registered energy audit. The federal Canada Greener Homes Grant provides up to $5,000 for home energy retrofits including insulation, plus $600 for required pre- and post-retrofit EnerGuide evaluations. You need a pre-upgrade energy audit, qualified contractor installation, and post-upgrade audit to qualify.
