what all the fuss is about
Why Spray Foam?
Why is spray foam insulation superior to conventional batt and blow-in insulation?

Imagine heading down the mountain on a perfect powder day. Would you rather tackle that slope in a stack of wool sweaters or a modern, wind-proof winter coat?
Conventional fiberglass and cellulose insulation is like those wool sweaters for your home. In ideal conditions, it slows down the movement of warm air out of your attic and walls. But add any sort of wind, and it cuts right through—brrr.
Spray foam, on the other hand, forms a tight seal wherever it's applied, preventing air leaks and drafts. This means no loss of warm air, which can greatly improve your home's energy efficiency and reduce heating and cooling costs.
Spray foam insulation also fills in small cracks and crevices that batt insulation might miss, providing a more complete insulation solution. It seamlessly tucks around all your doors and windows.
And here's the best part—spray foam insulation is more durable and long-lasting than batt insulation, which can settle and lose effectiveness over time. Apply it once, and you’re done.
Choosing spray foam insulation is like upgrading to that modern, wind-proof winter coat—it offers superior protection, comfort, and efficiency. Are you interested in a cozy and energy-efficient home? Give us a call and find out more about how spray foam can help you out.
