With freezing winters, hot summers, and wild temperature swings, Manitoba homes need insulation that can keep up. Spray foam insulation has become a top choice thanks to its energy efficiency, moisture resistance, and long-term value.

Why Spray Foam is a Top Choice for Manitoba Homes

1. Energy Efficiency Built for Manitoba’s Climate

Spray foam provides a high R-value and airtight seal, making it ideal for our -30°C winters and 30°C+ summers. It keeps warm air in during winter and hot air out in summer, reducing the strain on your HVAC system. Many homeowners see 20–30% savings on energy bills after upgrading.

2. Consistent Comfort, Fewer Drafts

Unlike traditional materials that can leave gaps or sag, spray foam expands to fill every corner. That means no cold spots, fewer drafts, and more even temperatures in every room. It’s a noticeable upgrade during blizzards or summer heat waves.

3. A Strong Moisture Barrier

Manitoba’s wet seasons can lead to condensation, leaks, and mould. Closed-cell spray foam acts as both an insulator and a moisture barrier, sealing out water and preventing rot, mould, and mildew. It’s especially effective in attics, crawl spaces, and basements.

4. Long-Term Savings and Durability

Though it has a higher upfront cost, spray foam insulation quickly pays for itself through energy savings and improved resale value. It lasts for decades—often 80+ years—without sagging or needing replacement. That makes it a one-time investment with lasting returns.

5. Healthier Indoor Air Quality

Spray foam seals out dust, pollen, and pests that often sneak in through gaps. It also helps prevent mould, keeping the air fresher and healthier, especially for allergy or asthma sufferers. No more itchy fibres or musty smells.

6. Ideal for Manitoba Homes—and Eligible for Rebates

Efficiency Manitoba and other programs offer rebates for insulation upgrades, especially in older homes. When installed by a qualified local contractor like Summit Insulation Services, spray foam often qualifies.
