OPEN-CELL SPRAY FOAM INSULATION
Open cell spray foam insulation is a smart, cost-effective way to improve comfort and energy efficiency throughout your home. It expands to fill every crack and gap, creating a powerful air seal that helps eliminate drafts and temperature swings. With its soft, flexible structure, it also provides excellent sound dampening between rooms and floors. Ideal for interior applications, open cell insulation delivers reliable performance while allowing assemblies to breathe, making it a great choice for comfort-focused, high-performance homes.

PERFECT FOR:
R-value per inch (R4.2 per inch)
Open cell spray foam provides an R-value of about R-3.8 per inch. While lower than closed cell, it delivers strong performance by expanding to fully air-seal cavities and reduce energy loss through air leakage.
OPEN-CELL SPRAY FOAM
Excellent air seal, expands up to 100x its liquid volume
Open cell spray foam acts as a powerful air seal, expanding up to 100x its original volume to fill every crack, gap, and void. This expansion creates a continuous barrier that helps eliminate air leakage, improving overall comfort and energy efficiency throughout the home.
THE BENEFITS OF
Soft, flexible structure that absords sound
Open cell spray foam is also an excellent sound-absorbing material. Its soft, porous structure helps reduce noise transfer between rooms and floors, making it a great choice for improving privacy and overall interior comfort in homes and buildings.
More cost-effective solution
Open cell spray foam is a cost-effective insulation option that delivers strong air sealing and comfort performance at a lower material cost than closed cell. It’s often used in larger interior areas where maximizing coverage and efficiency matters while staying within budget.
