Spray foam insulation is a polyurethane-based material that expands upon application, creating a seamless, airtight barrier that seals gaps, cracks, and voids in the building envelope. Available in two main types—open-cell and closed-cell—spray foam insulation offers distinct advantages and applications tailored to homeowners' specific needs.
Open-Cell Spray Foam
Characterized by its softer, lighter structure, open-cell spray foam is ideal for interior applications such as walls, ceilings, and floors. It provides excellent thermal insulation and sound absorption properties, making it an effective solution for noise reduction and indoor comfort enhancement.
Closed-Cell Spray Foam
Denser and more rigid than its open-cell counterpart, closed-cell spray foam excels in exterior and moisture-prone areas such as attics, crawlspaces, and basements. Its superior insulation, moisture resistance, and structural reinforcement capabilities make it well-suited for combating air infiltration, moisture intrusion, and thermal bridging.
