Chattanooga firefighters responded to a reported commercial fire shortly after midnight on Thursday at Woodbridge Foam Fabricating at 1138 Judd Road.
Battalion Chief David Thompson Jr. said that when firefighters with Quint 10 arrived on the scene and confirmed they had a fire at the rear of the building, a second alarm was requested to bring in additional firefighters and equipment.
Chief Thompson said the fire was located in a stack of foam blocks. The building's sprinkler system activated and helped to contain the spread of the flames. The fire was declared under control in about 45 minutes. No injuries were reported.
An estimate on the dollar loss was still being assessed, but most of the commercial business was spared any serious fire damage.
The cause of the fire will be ruled accidental.
