Why exposed foam in Hopkinton needs a coating

Hopkinton homes and what they need
Hopkinton, the starting line of the Boston Marathon, has older homes near the town center and many large colonials built since the 1990s.
Hopkinton's homes range from older houses near the town common, where the Boston Marathon begins, to newer subdivisions near Hopkinton State Park and Lake Maspenock. Many newer homes have large open attics and bonus rooms where better air sealing makes a noticeable difference.
Middlesex County is the most populous county in New England, with dense older cities near Boston and larger single-family suburbs further west.

Insulation targets and incentives in Hopkinton

Climate & code
Climate zone 5A targets
In climate zone 5A, which includes Hopkinton, recommended attic levels are R-49 to R-60, well above what most homes built before the 1980s were given. Many Massachusetts towns have adopted the Stretch Energy Code or the Specialized Opt-in Code, which raise insulation and air-sealing requirements for new construction and major renovations.

Massachusetts homeowners can start with a no-cost Mass Save® Home Energy Assessment, which can lead to incentives for insulation and air sealing. As a Mass Save® partner, BCI Group helps you through the program steps.

FAQ
Fire Retardant Paint questions in Hopkinton, MA
How long does it take?
Most basements and garages are coated in a day.
Does the coating change the foam's R-value?
No. It protects the foam without reducing its insulating value.
Can you coat foam another company installed?
Usually yes, once we confirm the foam product and its approved coatings.
Is coating cheaper than drywall?
Often, especially in large or irregular spaces like basements and metal buildings.
Do you document the thickness?
Yes. We measure as we go and provide product data for your inspector.
Does exposed spray foam in my Hopkinton basement need a coating?
