Choosing Spray Foam Insulation In Winnipeg
The Superior Choice for Winnipeg’s Extreme Climate
Winnipeg’s long, cold winters and windy conditions expose every air leak in a home. If you’re dealing with cold floors, drafty rooms, or damp basement spaces, spray foam insulation may be the right solution.
Spray foam insulation expands on application to seal cracks and gaps, creating an airtight barrier that improves energy efficiency, comfort, and moisture control. Unlike traditional fibre insulation, it both insulates and air seals at the same time.
Why We Recommend Spray Foam Insulation
Spray foam is especially effective in areas where air leakage and moisture are common concerns.
Closed-cell spray foam:
- Provides approximately R-6 per inch
- Acts as an air barrier and vapour barrier
- Does not absorb water
- Does not settle or sag over time
- Helps reduce drafts and uneven temperatures
In Winnipeg homes, spray foam is commonly used in:
- Rim joists and crawlspaces
- Basements and foundation walls
- Cathedral ceilings and attic slopes
- Select wall applications
In many cases, spray foam is used strategically in key areas and combined with fibreglass or cellulose insulation elsewhere to create a balanced, high-performance system.
Performance Benefits
Energy Efficiency
By sealing air leaks, spray foam helps reduce heat loss in winter and heat gain in summer.
Moisture Control
Closed-cell spray foam resists moisture and helps reduce condensation caused by warm indoor air leaking into cold spaces.
Improved Comfort
Eliminates drafts and helps create more consistent indoor temperatures.
Durability
Closed-cell spray foam does not shrink, crack, or deteriorate when installed properly.
Types of Spray Foam Insulation: Open-Cell vs. Closed-Cell
There are two types of spray foam insulation: open-cell and closed-cell.
At Above All Insulation, we use closed-cell spray foam for its higher R-value, moisture resistance, and structural rigidity. Its dense composition creates a durable, high-performance insulation layer suited for Winnipeg’s climate.
Where Can You Install Spray Foam Insulation?
Spray foam can be installed in:
Attics and Sloped Ceilings – Reduces air leakage in hard-to-insulate areas.
Walls – Used in specific applications where air sealing is critical.
Basements – Helps control moisture and improve comfort in damp areas.
Crawlspaces and Rim Joists – Addresses common sources of cold floors and drafts.
Installation time varies by project size. If spray foam is applied inside living spaces, the area must remain unoccupied during installation and for approximately 24 hours afterward to allow proper curing and ventilation.
FAQ
Is spray foam insulation safe for my family and pets?
Yes; when installed correctly by trained professionals, closed-cell spray foam insulation is safe and durable. During installation and curing, the area being sprayed must be properly ventilated and unoccupied. Once the foam has fully cured (typically within 24 hours), it becomes an inert material and does not release odours or gases under normal conditions.
Where does spray foam insulation make the most sense in Winnipeg homes?
Spray foam insulation is most effective in areas where air leakage and moisture are common concerns, such as basements, crawlspaces, rim joists, cathedral ceilings, and certain attic applications. Winnipeg’s cold, windy winters can force cold air through small gaps in these areas, and spray foam’s air-impermeable properties help eliminate drafts and improve comfort.
Will spray foam insulation help with cold floors and drafts?
In many cases, yes. Cold floors are often caused by air leakage around rim joists, uninsulated crawlspaces, or poorly sealed basement areas. Spray foam seals these gaps while providing insulation at the same time, which can significantly reduce drafts and improve overall comfort.
How long does spray foam insulation last?
When installed properly, closed-cell spray foam insulation is highly durable and designed to last for the life of the building. It does not sag, settle, or deteriorate over time like some traditional fibre insulation materials, even in areas exposed to air movement or moisture.
How long does spray foam installation take, and do I need to leave my home?
Installation timelines vary depending on the size and scope of the project. Some spray foam applications can be completed in under a day, while larger or more complex projects may take multiple days. If spray foam is applied inside living spaces, those areas must remain unoccupied during installation and for approximately 24 hours afterward to allow proper curing and ventilation.
Is spray foam insulation better than fibreglass or cellulose?
Spray foam insulation performs differently rather than simply being “better” in every situation. It excels at air sealing and moisture resistance, making it ideal for certain applications. Fibreglass or cellulose insulation can be more cost-effective for larger open areas like attics. In many Winnipeg homes, a combination of spray foam in critical areas and fibre insulation elsewhere provides the best balance of performance and value.
