Stop treating the steel skin as the whole building envelope
When warm, humid interior air reaches a cold metal surface, condensation can drip onto equipment, vehicles, stored materials, or finished spaces. A spray-foam plan should address the roof deck, wall panels, joints, penetrations, use of the building, access, ventilation, and re-entry—not just the number of square feet.
Buildings we spray foam
Pole barns
The scope should account for post spacing, open or finished walls, roof geometry, electrical work, livestock or storage use, and whether the space will be heated.
Metal buildings and steel roofs
The steel condition, fasteners, joints, panel profile, and underside access affect adhesion and preparation. The product must be approved for the substrate and application.
Detached garages and workshops
A workshop can have occupancy, ignition-source, ventilation, and equipment requirements that a storage building does not. Describe how the building is used before quoting.
Agricultural outbuildings
Ask about dust, animals, machinery, temperature, humidity, and the time the building needs to return to service. These factors affect containment and re-entry.
