Red Seal CertifiedWhy Does New Westminster 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.
New Westminster's historic homes sit on hilly terrain above the Fraser, built decades before modern insulation standards. Coastal rain and the river create constant moisture pressure, and spray foam's seamless air and vapor barrier is ideal for retrofitting heritage character homes without compromising their structure.
New Westminster's Insulation Challenges
As BC's oldest city, many heritage homes have little or no original insulation
Steep, hilly terrain above the Fraser exposes homes to wind-driven coastal rain
Pacific moisture promotes mould in the air gaps of century-old wall assemblies
Riverfront and SkyTrain density brings tight infill construction
How Spray Foam Helps
Spray foam seals heritage walls and crawl spaces against moisture older homes were never built to resist
Prevents mould in century-old Royal City homes by eliminating air gaps
Improves energy efficiency beyond code while preserving heritage structures
Ideal for retrofitting crawl spaces, rim joists, and additions in older homes

What Type of Spray Foam is Right for Your New Westminster 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.
New Westminster's Zone 4 climate and coastal rain and the fraser river load century-old heritage homes with moisture they were never sealed against 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 New Westminster: 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 New Westminster: 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 New Westminster 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 New Westminster. Here's what our local installers recommend.
Closed-Cell Spray Foam
New Westminster's high rainfall and coastal or interior moisture means closed-cell foam is the standard choice for basements, crawlspaces, and any below-grade area. Its built-in vapour barrier prevents moisture from migrating through the building envelope.
- ✓ 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 is a cost-effective option for interior partition walls, attic assemblies above the roof deck, and sound control between floors in New Westminster homes. It breathes freely, which suits dryer interior spaces.
- ✓ 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 New Westminster
