The Difference Between Open-Cell and Closed-Cell Spray Foam Insulation - Spray Foam Experts

When it comes to spray foam insulation, one common question Toronto homeowners ask is: “What’s the difference between open-cell and closed-cell foam?” The answer depends on your building type, insulation goals, and budget.

At Spray Foam Experts, we help our clients make informed decisions. Here’s a breakdown of both types:

Open-Cell Spray Foam
This type is softer and more flexible. It expands significantly, filling every nook and cranny — making it ideal for interior applications like attics, walls, and ceilings. Open-cell spray foam provides excellent soundproofing, making it perfect for homes in busy Toronto neighborhoods. It’s also more affordable than closed-cell foam.

Closed-Cell Spray Foam
Closed-cell spray foam is denser and more rigid, offering superior insulation performance and moisture resistance. It’s ideal for basements, crawl spaces, and exterior walls where moisture control and structural reinforcement are essential.

Choosing between the two depends on your property’s unique needs. Our professionals assess your home or business and recommend the best option to maximize efficiency and comfort.

We specialize in energy-saving insulation that keeps your home comfortable while drastically reducing heating and cooling costs. Spray foam creates a continuous air seal, preventing warm or cool air from escaping. As a result, your HVAC system runs more efficiently, extending its lifespan and lowering energy use. our Toronto customers often report energy bill reductions of up to 50% after installation. Beyond savings, spray foam also helps maintain consistent indoor temperatures and eliminates drafts.

Unlike traditional insulation, spray foam doesn’t sag, settle, or lose its effectiveness over time. It’s a long-term investment that pays dividends every month.
