Red Seal CertifiedWhy Does Fredericton Need Spray Foam Insulation?
Spray foam insulation seals air leaks and provides the highest R-value per inch, reducing heating costs by 30 to 50% in cold Canadian climates.
Fredericton's inland river valley location produces colder winter temperatures than coastal New Brunswick cities. The long heating season and many older homes with heritage character but poor insulation make spray foam retrofits particularly valuable. Closed-cell spray foam provides the high R-value needed for Fredericton's extreme climate.
Fredericton's Insulation Challenges
Fredericton experiences some of the coldest sustained winter temperatures in the Maritimes
Saint John River valley humidity creates condensation problems inside wall cavities
Many homes near the University and downtown area are 80–100+ years old with no insulation
Extended heating season from late September through May puts enormous demand on poorly insulated homes
How Spray Foam Helps
Spray foam maintains R-value performance even during Fredericton's deep cold snaps below -25°C
Air sealing stops cold drafts that make older Fredericton homes uncomfortable and expensive to heat
Closed-cell foam prevents the condensation issues caused by Saint John River valley moisture
Significant heating cost reductions help Fredericton homeowners manage long winter fuel bills

What Type of Spray Foam is Right for Your Fredericton Home?
Open-cell foam (R-3.7/inch) is ideal for interior walls and soundproofing, while closed-cell foam (R-6.5/inch) provides a moisture barrier for basements and exteriors.
Fredericton's Zone 6 climate and saint john river valley fog and humidity cause persistent condensation inside wall cavities conditions inform our recommendation for the right spray foam type.
Open-Cell Spray Foam
R-3.7 per inch
- Excellent soundproofing properties for interior walls
- More flexible—ideal for areas with movement or settling
- Allows moisture to pass through (breathable)
- Cost-effective for large interior applications
- Perfect for interior walls, attics (with vapor retarder), and floors
Best for Fredericton: Interior partition walls, soundproofing between rooms, and attic applications where a separate vapor barrier is installed.
Closed-Cell Spray Foam
R-6.5+ per inch
- Highest R-value per inch of any insulation material — ideal cold climate insulation
- Acts as its own vapor and moisture barrier
- Adds structural rigidity to walls and rooflines
- Resists water, mold, and moisture infiltration
- Ideal for exterior walls, basements, crawl spaces, and rim joists
Best for Fredericton: Exterior walls, basements, and any area where moisture is a concern. Provides the R-value needed for your climate zone.

"I ONLY WISH THEY INSTALLED OUR HEAT PUMP ORIGINALLY"
Great company to deal with. We hired them to move an existing heat pump after the original installer refused to help us. The estimator and the installer were both very polite, careful and thorough. I only wish they installed our heat pump originally. I would hire them again without hesitation.

Which Spray Foam Is Right for Your Fredericton Home?
There are two types of spray foam insulation — and the right choice depends on where it's being installed and the specific moisture challenges in Fredericton. Here's what our local installers recommend.
Closed-Cell Spray Foam
Fredericton's freeze-thaw cycles, coastal humidity, and Atlantic winters make closed-cell foam the preferred choice for most exterior applications. It acts as a combined insulator and vapour barrier — critical in Maritime climates where moisture in wall cavities leads to mould and rot.
- ✓ R-6 to R-6.5 per inch — highest R-value available
- ✓ Acts as a built-in vapour barrier — no separate poly required
- ✓ Adds structural rigidity to wall assemblies and rim joists
- ✓ Impervious to water — won't sag, settle, or absorb moisture over time
Open-Cell Spray Foam
Open-cell foam works well for interior walls, interior attic slopes, and any area in your Fredericton home where air sealing matters more than vapour control. It's also the better choice for soundproofing between rooms.
- ✓ R-3.5 to R-4 per inch — excellent air sealing at lower cost
- ✓ Superior soundproofing between rooms and floors
- ✓ More affordable per board foot — suited for large interior areas
- ⚠ Not suitable for below-grade or exterior applications in Fredericton
