Is open cell or closed cell spray foam better?

Neither type is best for every project. Open cell and closed cell foam have different densities, R-values and performance characteristics. The right choice depends on the building assembly, application and goals for the project.

Can spray foam be installed in an existing home?

Yes, in many situations. Spray foam can be used in existing homes during remodels, additions, attic improvements and other retrofit projects. We can evaluate the area being insulated and recommend an appropriate solution.

How much does spray foam insulation cost?

Cost depends on factors such as the size of the area, type of foam, required thickness and accessibility of the project. Contact A-Z Spray Foam for a project-specific estimate.

More Than Insulation

Spray foam expands as it is applied, allowing it to insulate and air seal areas where traditional insulation can leave gaps. When properly specified and installed, spray foam can help create a more comfortable, energy-efficient building while providing long-lasting insulation performance.

Helps reduce air leakage and drafts

Provides continuous coverage in hard-to-reach areas

Can improve indoor comfort and energy efficiency

Available in open cell and closed cell systems

Open Cell or Closed Cell Spray Foam?

Both can provide excellent insulation and air sealing, but they have different characteristics and applications. A-Z Spray Foam can help determine which system makes sense for your project.

Open Cell Spray Foam

Open cell spray foam is a lightweight, flexible foam that expands significantly during installation. It provides excellent air sealing and is commonly used in walls, ceilings, roof assemblies and other interior applications.

Commonly chosen for:

Homes and residential construction
Walls and roof assemblies
Attics and conditioned spaces
Projects where sound reduction is also beneficial

Closed Cell Spray Foam

Closed cell spray foam is a denser, rigid insulation that provides a higher R-value per inch than open cell foam. Its density and moisture-resistant characteristics make it well suited for many demanding residential, commercial and metal-building applications.

Commonly chosen for:

Metal buildings and shops
Commercial applications
Areas with limited space for insulation
Applications requiring greater R-value per inch

TALK TO A-Z SPRAY FOAM

The Right Foam.
The Right Application.

Good spray foam performance starts before the foam is applied. The type of foam, application area, required thickness and building assembly all matter.

At A-Z Spray Foam, we look at the project as a whole and recommend an insulation system based on the building and your goals. And because we offer more than spray foam, we'll help you find the right solution rather than simply trying to fit every project into the same product.
