    How Open-cell Spray Foam Insulation Supports Daily Comfort

    Open-cell spray foam insulation is applied as a liquid that expands and cures into a soft, flexible material. As it expands, it fills cracks and voids that traditional insulation often leaves behind.

    Because it remains flexible, this insulation adapts to normal building movement while maintaining its air sealing ability. Homeowners often notice more stable indoor temperatures and fewer drafts soon after installation.

    This insulation type is designed for airflow control rather than moisture blocking.
