Why Spray Foam Insulation in the Attic is the Best First Step

If your energy bills are through the roof, it might be because your heat is literally escaping through the roof. Insulating your attic with spray foam is the best place to start to improve your home’s energy efficiency without tearing down walls. Attics are one of the biggest sources of heat loss in a home and spray foam insulation is one of the most effective ways to cut energy costs, improve comfort, and even prevent winter headaches like ice dams.

Why Attic Insulation is Important

Heat rises, and if your attic isn’t properly insulated, the warm air you’re paying for is escaping through the roof. Up to 25% of heat can escape through an attic of a poorly insulated home¹. Traditional insulation like fiberglass or blown-in cellulose can leave gaps, settle over time, and require replacing. Spray foam on the other hand is a long-lasting material that expands to fill every gap and crack, creating a solid, airtight barrier that prevents heat loss. Plus, when it comes to R-values, closed-cell spray foam delivers the highest performance.

Upgrade with Spray Foam Without Tearing Up Your Walls

You don’t need to rip out drywall to benefit from spray foam insulation. A trained and certified professional can apply the foam directly to the underside of the roof deck or attic floor. It’s one of the best insulation upgrades you can make without the mess of a full renovation.

Ice Dams: How Spray Foam Prevents Damage

Ice dams are a common winter issues, often caused by heat loss through the attic. When heat rises and escapes through the roof, it melts the snow on top. The melted snow refreezes, forming a barrier that traps water behind it. This can lead to leaks, water damage, and roof damage.

How Spray Foam Helps Prevent Ice Dams

Proper attic insulation is the key to preventing ice dams, and closed-cell spray foam outperforms traditional types of insulation. Not only does it provide the strongest R-values and create an airtight seal, but it also acts as a built-in vapour barrier. In the winter, moisture from inside your home can rise into the attic and freeze when it reaches the cold roof. With closed-cell foam, like Insulthane® Extreme, the vapour barrier prevents this moisture from reaching your roof in the first place, reducing the chances of ice dams forming.

By stopping both heat loss and moisture buildup, closed-cell spray foam creates a reliable, energy-efficient enclosure that helps keep your roof temperature consistent. A warm, sealed attic means a reduced chance of ice dams forming and water damage.

Spray Foam your Attic and Start Saving

The attic is a great way to get started with spray foam insulation and will help you lower your energy bills, avoid ice dams, and improve overall comfort without the need for major renovations.
