Open-Cell Spray Foam Insulation
What is Open-Cell Insulation?
Open-cell spray foam insulation is a lightweight, cost-effective solution designed to provide excellent air sealing and thermal performance. It is made up of tiny interconnected cells that are left intentionally open, creating a soft and flexible foam once cured. Though it has a lower density and R-value (around R-3.5 to R-4 per inch) compared to closed-cell foam, it expands significantly upon application—filling even the smallest cracks and hard-to-reach cavities.
Because of its expansive nature, open-cell spray foam is ideal for interior applications such as attics, walls, ceilings, and between floor joists, where it provides effective insulation, sound dampening, and air barrier performance without adding structural weight.
One of the standout benefits of open-cell foam is its breathability, which allows for moisture permeability and helps prevent trapped condensation—especially useful in humid climates like Central Florida. While it doesn't serve as a vapor barrier like closed-cell foam, it is an eco-friendly and affordable insulation option that delivers strong performance in climate control and comfort.
Open-cell foam is widely chosen for residential insulation upgrades and new construction, offering a budget-conscious path to energy efficiency, noise control, and better indoor air quality.
Why Choose Open-Cell Insulation?
Open-cell spray foam insulation is a cost-effective, energy-efficient solution ideal for attics, walls, and ceilings. It expands to fill gaps and hard-to-reach areas, creating a seamless air seal that helps reduce drafts, lower energy bills, and improve indoor comfort.
This lightweight foam also provides excellent sound absorption, making it great for interior spaces where noise control is important. Its moisture permeability allows homes in humid climates like Central Florida to breathe, reducing the risk of trapped moisture and mold.
Affordable, eco-friendly, and effective—open-cell foam is a smart choice for homeowners who want long-term performance and better indoor air quality.
