By creating a seamless air seal, spray foam prevents outdoor pollutants, allergens, and dust from entering your home through gaps and cracks. It also mitigates moisture infiltration, which significantly reduces the risk of mold and mildew growth.
Yes, blown-in and dense-pack cellulose are excellent for historic homes. The materials are treated with borates, providing fire resistance and deterring pests, a common concern in older New England structures.
For most spray foam projects, we recommend vacating the property for 24 hours during and after the application. This allows for proper curing and ensures that any off-gassing is fully ventilated before you return to your comfortable home.
If you notice uneven temperatures between rooms, high energy bills, or ice dams forming on your roof in the winter, your insulation is likely insufficient. A quick visual inspection of the attic floor can also reveal if the material has settled below the floor joists.
Open-cell foam is lighter, more flexible, and great for soundproofing. Closed-cell foam is much denser, provides a higher R-value per inch, and acts as a vapor barrier, making it better for moisture-prone areas like basements.
Absolutely. While most people think of insulation for winter warmth, it is equally important for keeping heat out during hot Massachusetts summers. It reduces the load on your AC system, lowering electricity costs.
