The Top Myths About Attic Insulation (Debunked)

When it comes to attic insulation, there’s no shortage of myths and outdated advice floating around. At InsulationBC.com, we’re here to set the record straight — and help BC homeowners make smarter, more cost-effective decisions.

1. Myth: “My Home Was Insulated When It Was Built — It’s Fine.”

Fact:
Building codes 20+ years ago required far less insulation than today’s standards. In BC, homes now benefit from R50 or higher attic insulation to handle our damp, shifting climate.

2. Myth: “More Insulation Is Always Better.”

Fact:
Proper insulation is about balance. Over-packing your attic without ventilation can actually trap moisture, causing mold and rot. That’s why ventilation and insulation must work together.

3. Myth: “Insulation Only Matters in the Winter.”

Fact:
Attic insulation keeps your home cooler in summer, too. It blocks the sun’s heat from baking your living spaces, helping you save on AC costs and stay comfortable year-round.

4. Myth: “I Can Just DIY My Attic Insulation.”

Fact:
DIY insulation often leads to missed gaps, compressed material, and lack of airflow — all of which reduce effectiveness. Professional blown-in insulation ensures full coverage and optimal performance, plus surprisingly enough it can actually cost MORE with the retail cost of insulation, than having it installed.

5. Myth: “Insulation Doesn’t Affect Home Value.”

Fact:
Energy-efficient upgrades like attic insulation directly impact property value. Smart buyers in BC are now asking about insulation levels — and homes with energy improvements sell faster and for more.
