Why Does Sydney 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.
Sydney's Cape Breton location means longer, harsher winters than mainland Nova Scotia. Wind exposure from the Atlantic and Gulf of St. Lawrence amplifies heat loss. Many homes built during the industrial era lack adequate insulation, making spray foam retrofits especially impactful.
Sydney's Insulation Challenges
Cape Breton's exposed geography amplifies wind chill, increasing heat loss through poorly sealed walls
Heavy snowfall and ice buildup create moisture intrusion risks at rooflines and soffits
Many Sydney homes were built during the steel mill era with minimal insulation standards
Limited local insulation contractors mean many Cape Breton homes remain under-insulated
How Spray Foam Helps
Spray foam seals against Cape Breton's notorious wind-driven cold infiltration
Closed-cell foam provides a vapor barrier critical for Sydney's heavy precipitation climate
Local Greenfoot technicians serve Cape Breton directly, eliminating long service wait times
Proper insulation dramatically reduces heating costs for Cape Breton's longer heating season

What Type of Spray Foam is Right for Your Sydney 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.
Sydney's Zone 6 climate and heavy precipitation combined with strong ocean winds drives moisture deep into wall assemblies 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 Sydney: 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 Sydney: Exterior walls, basements, and any area where moisture is a concern. Provides the R-value needed for your climate zone.

"FIXED A LONG STANDING ISSUE I HAD FROM POOR INSTALLATION BY ANOTHER COMPANY!"
The two technicians Tanner and Halim were excellent, did a great job, very tidy, and identified 2 problems with my heat pump head, and fixed a long standing issue I had from poor installation by another company! Thank you very much, looking forward to using Greenfoot again.

"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.
Ellen DOWNEY - 5 Star Review

The young chaps, Marlon Marcuflo and Sylvia Richard, were wonderful to deal with. They were extremely polite, very tidy and efficient in their work, were right on schedule and did an excellent job.

Which Spray Foam Is Right for Your Sydney 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 Sydney. Here's what our local installers recommend.
Closed-Cell Spray Foam
Sydney'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 Sydney 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 Sydney
Not sure which type your Sydney home needs?
Our free home assessment determines the right foam type, thickness, and application areas — and we'll identify any provincial insulation rebates of up to $5,500 you qualify for. See available rebates →
