FAQ
Fire Retardant Paint questions in Waltham, MA
Is coating cheaper than drywall?
Often, especially in large or irregular spaces like basements and metal buildings.
Does the coating change the foam's R-value?
No. It protects the foam without reducing its insulating value.
Does exposed spray foam in my Waltham basement need a coating?
In most cases, yes. Code requires a thermal barrier between foam and living spaces, and an approved intumescent coating can meet that requirement.
What is intumescent paint?
A coating that swells when exposed to high heat, forming a protective char over the material underneath.
Can you coat foam another company installed?
Usually yes, once we confirm the foam product and its approved coatings.
Thermal barrier or ignition barrier?
Living and occupied spaces need a thermal barrier. Some attics and crawl spaces that are entered only for service may need an ignition barrier. We confirm which applies.
How soon can you start a coating project in Waltham?
Our crews travel about 22 miles from Westborough, MA to Waltham, and we group estimates and jobs by area. You'll get a start date with your written quote.
