Benefits of each Spray Foam Insulation Type

Most spray foam insulation comes in two kinds: open-cell and closed-cell. Natural-Therm comes in both of those types, plus one more: hybrid cell. When choosing what variety would be good for your project, there are several things to consider. We’ve tried to make that decision as easy as possible with the breakdown below.

Closed-Cell
Spray Foam Insulation

• Higher R-value per inch, better for tighter spaces
• Better for basements, crawlspaces, and exterior spaces
• Rejects large amounts of water, good for flood zones
• Adds strength to wall racking
• Less permeable for air, pests, moisture, heat
• Strongest structure

Open-Cell
Spray Foam Insulation

• Lower cost than closed-cell
• Better for interior spaces like walls and attics
• Better to fill large voids
• Stands up better to movement such as seasonal shifting
• Hydrophobic structure

Zero-Cell
Spray Foam Insulation

• Higher R-value to typical open cell foam
• More suitable for application where a harder foam is desired
• Hydrophobic structure
• Considered a low GWP product
