Pole Barn & Garage Insulation in Indianapolis, IN

Pole barn and garage insulation around Indianapolis covers a wide range of buildings: steel pole barns on acreage in Boone, Hendricks and Hancock counties, detached shops behind city homes, and attached garages under bonus rooms in the suburbs. Wikipedia notes that about 14,600 acres of farmland still lie inside Indianapolis city limits, and that about two-thirds of Boone County's land is in cultivation, so there are plenty of farm buildings in our area. What they share is that they were built to keep weather out, not to hold heat or keep moisture under control.

Why steel buildings drip

A steel roof cools fast at night by radiating heat to the sky. When warm, moist air inside the building touches the cold metal, water condenses on the underside and drips onto whatever is stored below: equipment, vehicles, hay or a workbench. Indianapolis summers make it worse; Wikipedia lists the city's average relative humidity at 72.3%. Closed-cell foam sprayed directly on the steel insulates it and keeps humid air off the cold surface, which stops the condensation where it starts. It also adds some rigidity to the panels and seals the gaps at laps and fasteners.

Choosing what to insulate

Not every building needs the same thing. A cold-storage barn that only needs the drip stopped may need a thin layer of closed-cell on the roof. A heated shop needs walls and roof insulated to a level that makes heating affordable. A barn with animals needs ventilation planned alongside any insulation. We ask how you use the building, then quote the thickness that matches. If you plan to add a heater, a mini-split or living space later, tell us; the plan changes.

Attached and detached garages

In suburban homes the attached garage is often the coldest part of the house, and the room above it is often the least comfortable. Foam in the garage ceiling under a bonus room both insulates the floor above and seals out garage air and fumes. The shared wall between the garage and the house is another common leak. For a detached garage you want to use as a workshop, open-cell or closed-cell foam in the stud walls and roof framing makes it practical to heat in winter and to work in on a summer afternoon.

Overhead doors and slabs

A large overhead door is often the weakest part of a garage or shop. Foam cannot go on a moving door, but we can recommend insulated door panels and seal the frame around the opening. Slab edges in heated shops lose heat too; if you are building new, rigid insulation at the slab edge is far cheaper to add before the pour.

Code and permits

A farm building and a heated living space are treated differently by building officials. If you are converting a barn or garage into living space, or adding plumbing and heat, check with your city or county building department before work starts. We can supply the foam type and thickness for your permit paperwork.

Planning around the weather

Foam needs the steel and the air within a working temperature range. Unheated buildings are easiest to spray in spring and fall. In winter we bring heat or wait for a milder stretch. Morning dew on the inside of steel has to dry before we spray, so summer jobs often start a little later in the day.
