What does it take to insulate a shop or office in Mandan?
Commercial insulation in Mandan means insulating the walls, roof and sometimes the floor of a shop, warehouse, office or metal building so it holds heat, costs less to run and is easier to work in. At R&T Mandan Spray Foam Insulation we plan each job around how the building is put together, because a steel building and a block one don't take the same approach.
Nobody calls us because their warehouse is too warm in January. Most business owners we hear from have a shop that won't hold heat, a heating bill that keeps climbing, or a space they're turning into something new. The price turns on the square footage, the wall and roof type, whether spray foam or a lighter material fits, whether old insulation has to come out first, and whether the foam needs a covering. The schedule turns on the same things, plus the permit and inspections when the job needs them, and your own price comes from the estimate we do at the building.
How we handle commercial insulation
We start with the wall and roof type, since that decides the approach, and a steel-framed building, a concrete or block wall and a wood-framed office each call for something different. Then we check what's already in there, because anything soaked, moldy or full of mouse droppings comes out before new material goes in, or the problem just gets buried. We do the air sealing next, closing the gaps around doors, roof edges and anything that runs through the walls, so the insulation isn't fighting a draft. Then we install the insulation and put up whatever covering the foam needs. That covering is spelled out in our quote, so it doesn't turn up later as a surprise. When we're done, the floor gets swept and the scraps leave with us.
Moisture is the other half of the job on a lot of buildings. Where warm, damp air inside meets a cold wall or roof, a vapor barrier installation keeps that moisture out of the insulation. If the building sits over a crawl space, a crawl space vapor barrier stops ground damp from working up into the floor.
Commercial insulation permits and buildings in Mandan
Mandan's Building Inspection Department issues building permits, and one is required to build, alter or repair a building inside city limits and within the city's 2-mile zone beyond them. Whether your insulation job needs one depends on the work, so if you're not sure, ask and I'll find out. Commercial permit questions go to the city's Building Department at 701-667-3230, and it's the city that enforces North Dakota's building code here, which was updated with new energy rules at the start of 2026. When your job needs a permit, we pull it and set up the inspections.
Around Mandan and Bismarck we see a lot of steel shops with a thin blanket stapled to the walls, and older block buildings with nothing behind the paneling but good intentions. We also get plenty of calls about roof panels dripping on cold mornings, which is why we check for moisture before we decide what goes in.

How much does commercial insulation cost in Mandan, ND?
Insulation in Mandan usually costs about $1 to $5 per square foot, as a general planning range for insulation, not a price for your building. Where your job lands in that range depends on the wall and roof type, the material and the covering foam needs. Your own number comes from the on-site estimate.
Does spray foam insulation need to be covered in a commercial building?
Yes, unless the foam is part of an assembly that passed large-scale fire tests. The model building codes require spray foam to sit behind a thermal or ignition barrier, a covering layer that slows a fire down, so the people inside have time to get out. Gypsum wallboard is one of the materials the codes list as a thermal barrier, so ask any installer which one they plan to use.
Is the covering over spray foam different in an attic or crawl space?
It can be. In certain attics and crawl spaces that people only enter to service utilities, the code allows a lighter ignition barrier over the foam. It gives less fire protection than a thermal barrier, which is why it's only accepted where hardly anyone goes.
What is the best way to insulate a metal building to meet energy code?
For a lot of metal buildings, a filled cavity system, which fills the space between the framing and holds the insulation there with banded facing or a liner, is quickly becoming a necessity to meet the current, stricter energy codes. Most commercial projects have to meet minimum levels for walls, roofs and floors, with separate targets for continuous insulation and cavity insulation. Ask whether a filled cavity system fits your building and how the plan meets each target.
How do I know if my commercial building's walls need continuous insulation?
Start with the wall type. One insulation maker's article says continuous insulation, an unbroken layer across the outside of the framing, is required on steel-framed walls across most of the country, and on concrete and block walls starting in the cooler parts of the country. That's why the wall type is the first thing we look at.
Will insulating a metal building make it quieter?
Yes. Metal building insulation greatly cuts noise, keeping outside sound out and soaking up the echo inside. If you've ever tried to take a phone call in a bare steel shop, you already know why that matters.
