4 insulation myths: what homeowners often get wrong 

Insulation is full of misconceptions. Many homeowners rely on outdated advice or half-truths that cost money and comfort. Let’s set the record straight.

Myth 1: “Insulation is only for winter”

In truth, insulation works year-round. It keeps heat in during winter, but it also locks cool air inside during summer and blocks moisture.

Myth 2: “Thicker walls are enough”

Without the right materials, thick walls won’t stop heat transfer or moisture damage. Performance depends on technology, not just mass.

Myth 3: “Any material will do”

Each home needs a tailored solution. Fiberglass, timber batt, and spray foam all perform differently — the wrong choice leads to waste.

Myth 4: “It’s just about saving money”

Lower bills are part of the story. But insulation also means better health, less noise, and stronger structures.

No more insulation myths

Knowing the truth about insulation is the first step to smarter decisions and to a home that truly protects.
