Steel Buildings in Tennessee Weather
Metal building and barn insulation solves two problems in Dickson County: heat in summer and condensation the rest of the year. Bare steel roofs turn a shop into an oven by afternoon. On cool nights the steel drops below the dew point of the humid air inside, and water condenses on the underside and drips onto equipment, hay or vehicles.
Closed-cell foam on steel
Closed-cell spray foam bonds directly to the steel, so humid air cannot reach the cold metal and condense. It also cuts the heat that radiates down from a sun-baked roof, and it seals seams and fastener holes. HomeGuide lists closed cell at $3.00 to $5.00 per square foot installed.
Shops, garages and barns
A shop you work in needs enough thickness to stay comfortable; a storage building may only need enough to stop dripping. Barns with animals need ventilation planned along with insulation, which we discuss before quoting. Many rural lots around Dickson, Charlotte and Centerville have one of each.
Coatings and rules
Depending on use, exposed foam may need a thermal or ignition barrier coating. We tell you which applies and include it on the quote.
