Selby Insulation returns your telephone call. That alone distinguishes Selby from the competition in Cedar City. We did a large bath remodel completely replacing tub and shower areas. Everything was ripped out to the studs. Shelby quoted a very reasonable price to (re)insulate all of the affected areas, arrived on site when they promised, and they did an outstanding job. Their on-site workers were pleasant, did their set-up and removal quickly and thoroughly without damaging (no nicks, no scrapes, no errors) and left the place cleaner than they found it. I enthusiastically, and without reservation, recommend Selby Insulation’s services.

Selby Insulation completed a relatively large basement insulation removal job for me. The workers were fantastic; smart, experienced, fast, thorough, and friendly. Also, the owner found a way to fit my job into their schedule the very next day after I called. I highly recommend Selby Insulation.

These guys were great. I called and they visited the site right away. They gave me a competitive quote with several options. They communicated with me on when they could come and completed the job on schedule. I needed to run a sewer vent up through the insulation and they came back and fixed it. Very halpy woth the job they did.

Had my 40x30 steel building garage done last fall. At first I was worried it wasn't sprayed on thick enough but he came back when he was in the area and tested a few areas and I got what I paid for, 2 1/2". This is the first real hot week so far and it's pretty miserable outside, I just walked into this garage and it's 65 in here...amazing. Well worth the money. I paid extra to paint the yellow sprayfoam grey....it was about $2500 for the grey paint but worth it when you consider it took all day and the cost of materials these days. We are getting another steel building installed in a few weeks and I will be calling to get the same insulation done again.

SOUTHERN UTAH SPRAY FOAM team was knowledgeable and professional. I was impressed with how quickly they came out for a bid and were able to get the job done. The foam set up evenly and consistently even though it was hot. Thank you!

Frequently Asked Questions — Spray Foam Insulation in Cedar City

Below are common questions Cedar City, UT homeowners ask about spray foam insulation cost, types, and installation. For local pricing and to compare verified contractors in Cedar City, browse the listings above.

Why is spray foam insulation especially important in cold climates like Cedar City?▼
In cold climates like Cedar City, UT, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in UT typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Cedar City?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Cedar City, UT. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Cedar City?▼
For cold climates like Cedar City, UT, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with UT building codes can recommend the exact specification for your home.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Cedar City, UT?▼
In Cedar City, UT and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Cedar City costs $2,000–$6,000. Most Cedar City homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Cedar City, UT?▼
When searching for a spray foam contractor in Cedar City, UT, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Cedar City contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Cedar City for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
