Summer in Canada may not come with the year-round heat of the south, but when it hits, it hits hard, especially in places like Edmonton, where homes are traditionally built to retain heat.
If you’re cranking the AC and still not comfortable, the problem may not be your HVAC system; it could be your insulation. That’s where open-cell spray foam comes into play.
Unlike traditional insulation materials, open-cell spray foam adapts to modern comfort needs with superior airflow management, thermal regulation, and sound absorption.
As more Edmonton homeowners prioritize energy-efficient upgrades and eco-conscious builds, open-cell spray foam is emerging as a summer essential for creating cooler, quieter, and more cost-efficient homes.
How Open Cell Spray Foam Improves Comfort In Warm Weather
Creates An Airtight Seal
Open-cell spray foam expands up to 100 times its original volume, filling every gap in framing cavities. This creates a continuous air barrier, preventing warm air from entering and cool air from escaping.
Stabilizes Indoor Temperatures
Homes with poor insulation often have temperature swings between floors. Open-cell spray foam helps eliminate hot spots and maintain consistent temperatures throughout the home.
Reduces AC Usage
By improving the envelope seal, open cell insulation helps reduce the demand on your air conditioner. Less work for your HVAC means lower energy bills and longer equipment lifespan.
Energy Efficiency That Pays Off
According to Natural Resources Canada, air leaks can account for up to 30% of energy loss in homes. Sealing these leaks with open-cell spray foam can significantly lower energy use, especially during the summer cooling season.
Homeowners often see measurable ROI in the first year after upgrading. And since the material won’t sag or settle over time, it keeps your home efficient for decades with minimal maintenance.
Sound Control
One of the lesser-known benefits of open-cell spray foam is sound dampening. Its porous structure absorbs sound waves, making it perfect for:
- Bedrooms and nurseries
- Home offices
- Shared walls or multi-unit homes
- Homes near traffic or construction zones
The result? A quieter, more peaceful indoor experience—without needing extra soundproofing materials.
Where It Works Best
Open cell spray foam is a versatile insulation solution, but where it really shines is in areas that need maximum airflow control and improved thermal stability. Here’s where homeowners in Edmonton see the biggest impact:
Attics
Attics are notorious for becoming ovens in the summer, especially in homes with older or poorly installed insulation.
Open cell spray foam creates an airtight seal along rafters and roof decks, reducing heat transfer and helping your cooling system keep up. It’s also ideal for vented attic systems.
Cathedral Ceilings
These beautiful architectural features often struggle with uneven temperatures. Open cell spray foam fills the narrow roof cavities common in cathedral ceilings and prevents hot air from pooling at the top of your home.
The result? A consistently comfortable space that looks as good as it feels.
Interior Wall Cavities
Installing open cell spray foam in interior walls offers two big benefits: thermal insulation and sound dampening. It’s a great way to cut down on noise transfer between rooms while keeping your home cooler throughout.
Ideal for bedrooms, nurseries, home offices, and anywhere you want peace and quiet, without sacrificing comfort.
What To Consider Before Installing
Not For High-Moisture Areas Like Basements Or Crawlspaces
While open cell spray foam is excellent at air sealing, it is vapour-permeable, meaning it can absorb and hold moisture over time. For this reason, it’s not recommended for use in below-grade or damp spaces such as basements or crawlspaces. In these cases, closed-cell spray foam or other moisture-resistant materials are a better fit.
Choose Pros Who Understand Local Code And Climate Needs
Insulating a home in Edmonton isn’t the same as in Vancouver or Toronto. Local weather patterns, building codes, and energy efficiency requirements all affect how spray foam should be installed.
Working with certified, Edmonton-based insulation contractors ensures your home gets the right solution for its specific challenges and that your project meets all fire and building code regulations.
Ensure Product Quality: Insulthane® 450 NM ocSPF Is A Trusted Option
Not all spray foams work the same way. At Classic Spray Foam, we rely on Insulthane® 450 NM ocSPF, a proven open cell product that delivers consistent expansion, adhesion, and long-term thermal performance.
It’s designed for Canadian homes and meets the performance standards needed for our climate. If you’re investing in insulation, you should expect it to last, and this product delivers exactly that.
Why Homeowners Are Choosing Spray Foam Over Traditional Options
Better Long-Term Value Than Blown-In Or Batt Insulation
While blown-in and batt insulation may seem cheaper up front, they often allow air leakage, settle over time, or require replacement sooner.
Open cell spray foam offers superior performance for decades, with fewer maintenance issues. Its ability to both insulate and air seal in one application gives it a higher return on investment, especially when it comes to energy savings.
Ideal For Renovations, Additions, And Energy Upgrades
Whether you’re finishing a bonus room, adding a home office, or upgrading your attic, open cell spray foam fits easily into the plan. Its lightweight, expansive nature allows it to insulate irregular cavities and tricky corners without adding significant structural load, perfect for modern renovations that demand performance and efficiency.
Pairs Well With Energy-Efficient Cooling Systems
Installing open cell spray foam is like giving your home a cooling assist. It helps HVAC systems operate more efficiently, reduces run times, and minimizes energy loss through walls and ceilings. That synergy means better comfort and lower utility bills, a win for your wallet and the environment.
