Homes in our region face significant temperature fluctuations and high humidity from nearby water sources like the Wachusett Reservoir. Spray foam creates an airtight, moisture-resistant barrier that prevents humid summer air and freezing winter drafts from penetrating your living spaces, ultimately stabilizing your indoor climate.
Open-cell foam expands significantly to fill complex cavities, providing excellent sound dampening and air sealing for interior walls. Closed-cell foam is denser, offering a higher thermal resistance value per inch, and acts as a rigid vapor barrier that adds structural strength, making it ideal for basements, crawlspaces, and exterior walls.
Removal is highly recommended when existing materials have been compromised by water damage, pest infestations, mold growth, or heavy settling over the decades. Extracting this old material ensures that your new thermal application adheres properly and maintains healthy indoor air quality.
Building codes often require exposed foam in accessible areas (like attics or basements) to have a fire barrier. Intumescent coatings are specialized paints applied directly over the foam; in the presence of extreme heat, they expand to form a protective char layer, significantly delaying fire spread and meeting strict safety regulations.
Absolutely. Dense-pack cellulose is injected at high pressure into existing wall cavities without tearing down drywall or plaster. It effectively packs around older wiring and plumbing, blocking the hidden airflow channels that cause persistent drafts in aging New England architecture.
