Why spray foam

What does spray foam do for a Phoenix attic that can reach 150 F?

In a Phoenix summer, an attic can reach 150 F. That heat sits on your ceiling and your ductwork all afternoon, and every gap in the ceiling lets some of it into the house. Blown-in and batt insulation slow heat down. Spray foam does that and seals the air leaks in the same pass, because it expands to fill cracks, gaps and penetrations as it goes on.

On a roofline job, we spray the underside of the roof deck so the attic, and any ductwork or air handler up there, sits in a milder space. Foam Pro Insulation sprays two products, open-cell and closed-cell, and the right one depends on the building. Every job starts with a free thermal-imaging attic inspection of about 30 minutes, and we show you the photos before we talk price.

Open-cell vs closed-cell

Which spray foam fits your Phoenix property?

Two foams, two jobs. We pick the one that fits your building after the inspection.
Compare	Open-cell spray foam	Closed-cell spray foam
R-value per inch	About R-3.6 to 3.9	About R-6 to 7
Where it fits	Roofline encapsulation in Phoenix attics, and most residential retrofits	Metal buildings, exterior applications, new construction, and spots where cavity depth is limited
What you get	Cost-effective coverage over large areas, a semi-conditioned attic that protects HVAC equipment, and quieter rooms from sound dampening	The most R-value in the least depth, a rigid finish that adds structural support, and strong resistance to moisture
Pricing	Custom quote	Custom quote

Not sure which one you need? Your free attic inspection answers it, and the quote is built around the area and thickness we measure.

Protection for HVAC systems and your belongings
Substrate cleaning, and primer where it is needed

2Precision application

Temperature-controlled mixing so the foam expands properly
Layer-by-layer spraying to reach the target R-value
Extra attention at top plates, penetrations and transitions

3Quality verification

Thickness measured at multiple points
Thermal imaging to confirm complete coverage
Post-cure inspection to check adhesion

4Final handoff

Before and after photos for your records
Care instructions for your new foam

Energy bills

Lower your APS or SRP bill by keeping the heat out

Most of a Phoenix cooling bill is your AC fighting the heat that leaks in from above. Spray foam goes after both parts of that problem, the temperature and the air leaks, in one application.

We also help homeowners with APS and SRP insulation and duct rebates. Ask us during your inspection what to look into for your home.

Spray foam questions

Spray foam insulation in Phoenix: common questions

How much does spray foam insulation cost in Phoenix?

Spray foam is a custom quote. The price depends on how much surface we are covering, how thick the foam needs to be, and whether it is open-cell or closed-cell. We start with a free thermal-imaging attic inspection, measure the job, and give you a same-day quote with the numbers laid out.

What is the difference between open-cell and closed-cell spray foam?

Open-cell foam gives about R-3.6 to 3.9 per inch and covers large areas cost-effectively. Closed-cell gives about R-6 to 7 per inch, so it fits where depth is limited. Closed-cell is also rigid and resists moisture, which is why we use it on metal buildings and exterior work.

Which spray foam is right for my Phoenix attic?

For most Phoenix homes, open-cell on the roofline is the popular choice. It turns the attic into a semi-conditioned space that protects your HVAC equipment. Closed-cell makes sense where rafters are shallow or you want the most R-value per inch. We confirm which one fits during your attic inspection.

How does a spray foam job work from start to finish?

We mask everything that should stay clean, protect your HVAC system and belongings, and prep the surface. Then we mix and spray in layers until we reach the target R-value. After that we measure thickness, check coverage with thermal imaging, and give you before and after photos for your records.

Where do you install spray foam insulation?

We work across the Phoenix metro from our base in Glendale, including Phoenix, Scottsdale, Chandler, Mesa, Gilbert, Peoria, Surprise, Goodyear and Buckeye. That covers homes, shops and metal buildings. Our own crews do the work, and we never subcontract it, so the people who quote your job are the ones who spray it.

Are there APS or SRP rebates for spray foam?

We help homeowners with APS and SRP insulation and duct rebates. Programs and requirements are set by the utilities and can change, so we do not quote rebate amounts here. Ask us during your inspection and we will walk you through what to look into for your home and the work you are planning.
