Built for real Phoenix summers.
Spray foam insulation for Phoenix, Arizona homes and businesses — IECC Climate Zone 2B, an ASHRAE 1% summer design temperature around 108°F, and an AC bill that shows it. Open-cell and closed-cell foam for attics, walls, garages, and new construction, built to stop desert heat before it reaches your thermostat.

Phoenix's climate runs on heat, not cold. Your insulation should be built for that.
Phoenix sits in IECC Climate Zone 2B — a genuine hot-dry desert climate where the roof deck takes direct sun for most of the day and the ASHRAE 1% summer design temperature runs around 108°F. The Department of Energy's general guidance for hot-dry Zone 2 homes points to attic insulation in the R30 to R60 range, and a lot of Phoenix homes, especially the mid-century and 1970s-90s tract housing that makes up so much of the Valley, are running well below that.
Spray foam insulation is built for exactly this kind of climate. It insulates and air-seals in a single application, stopping the infiltration of superheated attic air that drives up cooling bills — and closing the gaps that fiberglass batts lie across without ever sealing. Traditional insulation alone can't do either of those things.
We're a dedicated spray foam insulation specialist for Phoenix and the Valley of the Sun — not a generalist treating every Arizona climate the same way.

Comfort and savings, built for the desert.
Desert heat control
Sealing the attic and roof deck stops the radiant-heat-into-living-space problem at the source, instead of just asking your AC to keep up.
Zone-2B-appropriate R-values
We build to DOE guidance for hot-dry Zone 2 homes — attic R30-R60 — not a generic one-size-fits-all number.
Local, honest advice
We recommend open-cell, closed-cell, or a mix based on your home's actual needs — never a one-size-fits-all pitch.

Phoenix spray foam insulation FAQs
Phoenix sits in IECC Climate Zone 2B, a hot-dry desert climate where the ASHRAE 1% summer design temperature runs around 108°F and the roof deck takes direct sun exposure most of the day. Air conditioning typically makes up the largest single share of a Phoenix home's summer electric bill, and an under-insulated, poorly air-sealed attic is one of the biggest reasons AC units run longer than they should.
Spray foam insulation in the Phoenix area typically runs $1 to $5 per square foot installed, averaging around $3 per square foot, with open-cell at the lower end and closed-cell at the higher end. A typical attic or garage project often falls in the $1,500-$2,500+ range depending on square footage. A free on-site assessment gets you a firm number for your home.
Open-cell is lighter and less expensive, a strong fit for interior walls and vented attic-floor coverage. Closed-cell is denser, delivers the highest R-value per inch (R-6 to R-7), adds structural rigidity, and resists moisture — making it the right call for roof decks and garages facing Phoenix's most extreme heat exposure.
For homes with under-insulated attics or leaky building envelopes, yes — often meaningfully. Spray foam air-seals and insulates in one step, which stops the infiltration of superheated attic and exterior air that drives up AC runtime through a Phoenix summer. Industry estimates suggest 30-50% cooling-cost reductions are achievable for a poorly insulated home.
This is almost always a garage-ceiling insulation issue, not an AC problem. An uninsulated garage regularly runs hotter than outdoor air in summer, and that heat rises directly into the floor of any room built above it. Spray foam on the garage ceiling closes that heat pathway at the source.
