Spray Foam Insulation in Bentonville, AR

Our shop sits on Brookside Road, which makes Bentonville the city where a spray foam crew spends the least time driving and the most time working. It also means we have been in and out of Bentonville attics since 1996, long enough to watch the city split into two very different kinds of house, each with its own reason to call about foam.

The older homes near the square

The established neighborhoods around Downtown Bentonville hold homes built well before current insulation code, and the problem in most of them is not just thin insulation. It is air movement. Warm air escapes through gaps at the top plates, around recessed lights, and up through the attic hatch, and no amount of loose material stops that on its own. Spray foam does, because it insulates and air seals in a single pass. Open cell foam, at roughly R-3.7 per inch, expands aggressively into the irregular framing these older houses are full of, and it stays vapor permeable so the assembly can dry.

If an older home near the square simply needs depth and its air sealing is adequate, we will say so, because blown-in fiberglass is the cheaper fix for that condition and we install both.

Bonus rooms in the growth-year subdivisions

The subdivisions that filled in through Bentonville's growth years, places like Central Park, Rolling Hills, and Willowbrook, were built tighter. What they have instead is a pattern we see constantly: the bonus room over the garage that never matches the thermostat, and the vaulted ceiling that bakes in July. A bonus room has conditioned space on one side and outdoor temperatures on the other five, which is exactly the situation foam was made for. Sealing and insulating the knee walls and roofline of that one room is a small job that changes how the whole upstairs feels.

Closed cell foam, denser and roughly R-6.5 per inch, is what we reach for at rim joists, in metal shops, and on crawl space walls as part of a full crawl space encapsulation. It costs more per board foot, so it goes where its moisture resistance earns the difference, not everywhere.

What an install looks like when the shop is this close

Every Bentonville job starts with an inspection rather than a quote. We look at what the attic actually has, where the leaks are, and whether there is any moisture history, and because the drive is minutes rather than an hour, getting on the schedule is fast. Sometimes the inspection ends with us telling you the insulation is adequate and the problem is elsewhere. We would rather do that in our home city than anywhere.

On install day the crew masks the work area, sets up ventilation, and applies foam in controlled lifts to the specified thickness, because curing generates heat and rushing it compromises the result. Most residential projects run one to two days, and you get the exact re-entry time in writing before we start.

Spray foam is one of three things we do here; the Bentonville insulation page covers how the services fit together across the city. When you want a number for your own house, the estimate is free, in person, and in writing before any work begins.
