Closed-Cell Spray Foam

Dense foam with the highest R-value per inch. Adds rigidity and resists moisture, so it is the go-to for crawl spaces, rim joists and tight spaces that need a vapor barrier.

Best for: crawl spaces, rim joists, where space is limited or moisture is a concern.

Open-Cell Spray Foam

Lighter, softer foam that is an excellent air seal at a lower cost per board foot. A strong choice for interior walls and many attic assemblies.

Best for: walls, many attics, cost-effective air sealing.

Blown-In Insulation

Loose fill blown to an even depth across the attic floor. Flows into corners and around obstructions for consistent coverage and a real R-value.

Best for: attic floors, topping up thin or settled insulation.

Batt Insulation

Pre-cut material fitted into open cavities. Cost-effective and effective when installed correctly, with no gaps or compression.

Best for: new construction walls, floors, vented attic assemblies.

The Honest Answer Is Usually "It Depends"

A good insulation company should be able to tell you when a cheaper option is the right one. During a free estimate we look at your specific attic, walls or crawl space and recommend what actually fits, not the most expensive product on the truck.

Common Questions

Which insulation is best for my home?

It depends on the area, your goals and your budget. There is no single best product for every part of a house. The right answer is often a combination: foam or air sealing where it matters most, and blown-in or batt where those are the smart, cost-effective choice.

Is spray foam always better than batt or blown-in?

No. Spray foam is excellent for air sealing and tight spaces, but batt and blown-in are the right, more affordable call in many assemblies. We recommend based on the area, not on price.

What is the difference between open-cell and closed-cell foam?

Closed-cell is denser, gives more R-value per inch, adds rigidity and resists moisture. Open-cell is lighter, a strong air seal, and costs less per board foot. We match the type to the space.

Do I need air sealing on top of insulation?

In most homes, yes. Insulation slows heat transfer, air sealing stops leaks. Doing both is what delivers the comfort and savings people expect.

How do I know how much R-value I need?

It varies by assembly and where it is in the home. We measure what you have and recommend an appropriate R-value to add during your free estimate.
