6 Common Insulation Myths Debunked

When it comes to keeping your Northern Ontario home warm in the winter and cool in the summer, insulation plays a vital role. Yet despite its importance, there’s no shortage of misinformation out there. Whether passed down from neighbour to neighbour or outdated advice from decades past, each insulation myth can lead to poor decisions, wasted money, and uncomfortable living conditions.

At Polar Bear Spray Foam Inc., we believe in educating our customers. Let’s break down six of the most common insulation myths and uncover the truth every homeowner in Northern Ontario should know.

🧊 Truth: While it’s tempting to believe that adding more and more insulation will boost performance, this insulation myth misses a crucial point—quality matters just as much as quantity. Simply piling up insulation without addressing air leakage, thermal bridging, or material type can result in diminished returns. In fact, a professionally installed 3-inch layer of closed-cell spray foam often performs better than a much thicker layer of poorly applied fiberglass or cellulose. When installed correctly, high-performance insulation like spray foam provides better air sealing, moisture control, and energy efficiency

🌞 Truth: This is a common insulation myth, especially in colder climates like Northern Ontario. While insulation is essential for trapping heat during our long winters, it also plays a major role in keeping your home cool during summer. Without proper insulation, your attic can become a heat trap, making your A/C work overtime. Insulation helps regulate indoor temperatures year-round, reducing both heating and cooling costs. Investing in proper insulation means comfort in every season—not just when the snow falls.

🧪 Truth: This outdated insulation myth often stems from confusion around the spray foam curing process. While it’s true that uncured spray foam should not be disturbed, the product used by Polar Bear Spray Foam Inc. – Genyk’s Boreal Nature Elite closed-cell spray foam, is certified safe and environmentally responsible. Once fully cured, this Canadian-made closed-cell spray foam becomes inert, non-toxic, and safe for long-term use. With certifications like CCMC, Greenguard, LEED, and an Environmental Product Declaration, it’s one of the most thoroughly vetted insulation products on the market.

🏚️ Truth: Don’t fall for this limiting insulation myth—older homes can absolutely be upgraded. While retrofitting insulation in century homes or older cottages requires care and expertise, modern techniques such as spray foam injection, blown-in cellulose, and hybrid insulation systems make it possible to significantly improve comfort and energy efficiency. In fact, insulating an older home is one of the best ways to preserve its charm while reducing your heating bills.

🔍 Truth: Believing this insulation myth can result in choosing the wrong material for your project. Each insulation type—whether it’s fiberglass batts, blown-in cellulose, or spray foam—offers different performance characteristics. For example, spray foam not only insulates but also seals air leaks and acts as a vapor barrier, making it ideal for damp basements, crawl spaces, and hard-to-reach attics. A one-size-fits-all approach doesn’t work; the right solution depends on your home’s specific needs and the unique climate conditions of Northern Ontario.

🛠️ Truth: This final insulation myth is risky and often costly. While DIY kits tempt some homeowners, professional insulation contractors bring expertise, tools, and product knowledge that ensure the job is done safely and effectively. Improperly installed insulation can lead to air gaps, moisture issues, and long-term performance problems. With Polar Bear Spray Foam Inc., you’re not just getting insulation—you’re getting the Polar Bear Hug: quality workmanship, certified materials, and results you can trust.
