Metal Building Insulation in North Idaho

Empire Insulation sprays closed-cell foam directly onto the steel in metal buildings across North Idaho, including arched and Quonset-style buildings. Steel moves heat right through it and sweats when temperatures swing. Foam stops the air and vapor that reach the cold metal, slows heat loss and seals the seams. Nick Bond quotes and sprays it himself.

Keep the water off your steel and the heat inside

Closed-cell foam sprayed against the panels keeps warm, moist air away from cold steel, so less drips on what you store and less heat leaks out.

Why the foam goes right on the steel

Metal is a poor insulator: heat moves right through it. When temperatures change fast, or inside and outside are far apart, the steel drops below the dew point and water forms on it. Fiberglass doesn't stop that. Air moves through fiberglass and sets up convection loops, so condensation forms behind it. Closed-cell foam sprayed straight onto the steel stops the air and the vapor drive, so it insulates, seals the seams and keeps moisture off the cold metal in one pass.

Arched and Quonset-style buildings get the same treatment, and spray foam is the only way to insulate them. The panels need to be clean and dry enough for the foam to bond. You can do the cleaning and rust prep yourself to save money, or Empire can include it in the quote. Nick talks through the panels, how you use the building and what you want covered before he gives a firm price.

Nick runs the rig himself and stays on site from start to finish. Ratio monitoring tracks the foam mix while he sprays, and an application report is available on request.

Bare steel moves heat fast and sweats when warm air hits it. These are the problems foam on metal is used to solve.

  • Dripping on equipment and stock

    When the steel drops below the dew point, water forms and drips onto whatever sits below. Closed-cell foam on the steel stops the air and vapor that cause it.

  • Arched and Quonset buildings

    Empire insulates arched and Quonset-style buildings. Spray foam is the only way to insulate them: it goes on from the floor up over the whole curved shell.

  • Heat leaking out through bare panels

    Steel passes heat quickly. Foam adds insulation right on the panels, so a heated building holds its temperature longer.

  • Drafts at seams, doors and eaves

    Foam fills seams and the gaps around doors and framing, so cold air has fewer ways in.

  • A metal shop you want to work in

    If you spend winter days in the building, foam turns cold steel into a shell your heater can keep up with.

  • Steel shipping containers

    Containers are on Empire's project list. Foam on the steel walls and roof insulates and seals the inside in one pass.

  • Panels that need prep first

    Dirt, rust and moisture affect how foam bonds. Clean the panels yourself to save money, or have the prep included in the quote. Fix any roof leaks before spray day.

These are Empire's own jobs. Look at how the foam follows the ribs of corrugated metal, covers an arched building from the floor to the crown and fills the roof between the purlins above an overhead door.

Customer reviews & pricing

  • I've utilized many insulation companies over the years and rarely write reviews, but Nick and his guys did an outstanding job and I would HIGHLY recommend them. Their price was excellent, the work was perfect, and they are extremely clean and organized.

What affects the price

Every metal building is quoted on its own, and estimates are free. Price follows the steel area covered, the condition of the panels and access, not the floor size.

JobWhat affects the quote
Metal Building Insulation Steel area covered, surface condition and access
  • Steel area covered: Roof and wall panels set the base. Floor area alone does not tell you how much steel needs foam.
  • Foam type and thickness: Empire sprays 2-lb closed-cell and HFO closed-cell. Thickness changes the material used and depends on how you heat the building.
  • Surface condition: Clean, dry panels are ready to spray. If the steel needs cleaning or rust prep, you can do it yourself to save money, or Empire can include it in the quote.
  • Access and building shape: Tall walls, curved panels, equipment inside and tight spots change how the steel is reached and how long the work takes.
  • How the building is used: Cold storage typically gets 4 inches on the walls and 6 on the roof; heated shops usually less. A space people work in may need a covering over the foam.

Questions we get

Will spray foam stop my metal building from sweating?

Closed-cell foam is how Nick deals with it. Metal moves heat right through it, so when temperatures swing the steel drops below the dew point and water forms. Foam sprayed against the panels stops the air and the vapor drive that carry moisture to the cold steel. It won't fix a roof leak, so sort out any leaks before the foam goes on.

Why not use fiberglass in a metal building?

Air moves through fiberglass and sets up convection loops, so moist air still reaches the cold steel and condensation forms behind the batts. On a roof deck, fiberglass also needs vented airflow the building usually isn't built for, and it tends to fall down after some years. Spray foam bonds to the steel and stops the air and vapor.

Do you insulate arched or Quonset-style buildings?

Yes. Spray foam is the only way to insulate an arched or Quonset-style building. Closed-cell foam goes on from the floor up over the whole curved shell and the end walls, and it bonds to the corrugated metal. Send photos and the building's size, and Nick can give you a rough number.

Request your free estimate

Does the foam need to be covered?

If people will work in the building, usually yes. Spray foam is combustible, and codes generally call for an approved thermal barrier, such as gypsum drywall, between foam and occupied space. Empire can paint exposed foam for a finished look, but ordinary paint is not a thermal barrier. Requirements depend on the product, how the space is used and local code.

What happens on spray day?

Empty the building as much as you can and fix any leaks first. If you physically can't move everything, tell Nick and the crew will help. Nick sprays with one consistent crew member and stays on site start to finish. Everyone else stays out of the work area during spraying, cleanup and the product's re-occupancy period, so ask for the return instructions before you schedule.

What should I send to get an estimate?

Call, text or use the form with the building's rough size, how you use it, the condition of the panels and what you want insulated. Photos of the steel and framing help. Nick gives a rough number from that and a firm quote once he has seen the building. Estimates are free, and veterans and service members get a discount that depends on the job.

  1. Reach out

    Call, text or send the form with your building and what you want insulated.

  2. Rough estimate, then a firm quote

    Nick gives a rough number from what you send, then a firm quote once he has seen the job. Simple pole barns can often be quoted remotely.

  3. Clear the building

    Move everything you can off the floor and out of the way. If you physically can't, tell Nick and the crew will help.

  4. Spray day and cleanup

    Nick sprays the foam with one consistent crew member and stays on site throughout. Jobs are left cleaner than when the crew arrived.
