Steel Buildings in Gulf Heat
Metal building insulation solves two problems at once on the Coast. Bare steel roofs and walls soak up sun and radiate heat inside, so an uninsulated shop is miserable much of the year. And when humid air meets steel that has cooled overnight or is being air conditioned, the steel sweats, dripping on tools, vehicles and stored goods and rusting fasteners.
Closed-cell foam on steel
Closed-cell spray foam applied directly to the inside of the panels insulates, seals the seams and keeps humid air off the metal, which stops the sweating. HomeGuide lists closed-cell at $3.00 to $5.00 per square foot installed.
Cooling a shop
If you plan to air condition the building, foam makes that practical. The thickness depends on how you use it: a climate-controlled workshop needs more than a storage building you just want to keep from dripping.
Inland lots
Communities like Saucier and Vancleave have larger lots, many with a metal shop or barn. We insulate those as well as attached and detached garages.
Permits
Check with your city or county about permits for converting a building to conditioned space.
Wall girts and roof purlins
In steel buildings the foam goes onto the inside of the panels between the girts and purlins. We cover the framing members where needed to stop them becoming cold bridges that drip.
Doors and openings
Roll-up doors, walk doors and vents are the weak points in an insulated metal building. We seal around frames and can discuss insulated door options with your door supplier.
Coatings and barriers
Depending on the building's use, foam may need a thermal or ignition barrier coating. We go over what applies before quoting.
