Spray Foam Insulation

Oklahoma heating and cooling bills are high partly because of our extreme temperature range and partly because a large number of homes in the region have attic assemblies that were never properly air-sealed. Insulation stops conductive heat transfer. Spray foam stops both conduction and convection. That distinction is why two houses with the same rated R-value can have dramatically different energy bills.

Aero Precision applies open-cell and closed-cell spray foam for residential and commercial projects across Cleveland, Tulsa, Owasso, Stillwater, Bartlesville, and Ponca City.

Why Air Sealing Changes the Equation

Most homes built in Oklahoma before the mid-2000s have unsealed attic bypasses — gaps around plumbing stacks, wiring penetrations, recessed lights, and top plates that allow conditioned air to move directly from living space into the attic. You can pile R-60 worth of blown fiberglass on the attic floor and still have an uncomfortable, expensive house if those bypasses are open.

Closed-cell spray foam addresses this in a way no other insulation product does as well. Applied to the underside of the roof deck, it creates an unvented attic assembly — the attic becomes part of the conditioned envelope. HVAC equipment and ductwork in the attic, which is extremely common in Oklahoma, suddenly operates in conditioned air rather than 140-degree summer heat. The efficiency improvement in those cases is dramatic. For homes also getting new replacement windows or exterior door upgrades, spray foam in the same project seals the wall cavities at penetrations that those trades open up anyway.

Choosing the Right Foam

• Closed-cell — R-6 per inch, vapor barrier properties, adds structural rigidity; required at roof deck and critical moisture planes
• Open-cell — R-3.7 per inch, excellent air sealing, better sound attenuation; cost-effective for large attic volumes and interior walls
• Hybrid systems — closed-cell at the moisture control plane, open-cell fill above; used where both vapor management and volume coverage matter

Crawl Spaces and Wall Assemblies

Crawl spaces in homes across northeast Oklahoma often have exposed ground and minimal insulation. Encapsulating the crawl space floor and walls with closed-cell foam and a vapor barrier addresses moisture infiltration, pest pressure, and the cold floors that are a persistent complaint in older homes in Bartlesville and the surrounding area.

Spray foam also has a place in new construction. When we build out a barn or workshop, spray foam in the wall and roof panels is what separates a climate-controlled shop from a heated tin box. For new residential construction or additions, specifying spray foam at the framing stage produces a significantly tighter envelope than retrofitting it later.

If your home is uncomfortable despite adequate-looking insulation, an air leakage problem is the likely culprit. Call us for an assessment — we’ll show you where the losses are before recommending any work.
