Difference Between Closed and Open Cell: Which one is best for me?

Open Cell

Open cell spray foam is lightweight, flexible, and ideal for interior insulation projects like walls and ceilings. It expands to fill every gap, helping to reduce drafts, moisture, and outside noise. This breathable solution is cost-effective and perfect for homes throughout Northern Virginia and Maryland.

Closed Cell

For maximum durability and insulation value, closed cell spray foam is the top choice. It adds structural strength while providing a higher R-value per inch — perfect for basements, foundations, roofs, and commercial settings. We use premium-grade materials to ensure lasting performance in every climate zone from Annandale, VA to Gaithersburg, MD.
