RE: 32 Woodbine Ave. West Yarmouth MA.
Dear: Building Department.
The International Building Code mandates that spray polyurethane foam be separated
from the interior of the building by a 15 minute thermal barrier or other approved
covering. DC 315 passed certified NFPA 268 and UL 1715 over a variety of open and
closed cell spray applied urethane foams that were conducted by certified testing
facilities.
DC 315 Thermal Barrier covers-88.88 sq. ft. /gal @ 18 mils wet and 12 mils dry NFPA 286
(AC377)
The space that the foam was left exposed was approximately 1,300 sq. feet and we used
14.606 gallons of DC315 paint. (Attic area)
18 WFT > 89 Sq. Ft. per One Gallon > 445 Sq. Ft. per Five Gallon
