"We have a 30 year old home that had only 6" of Cellulose insulation in the attic. Now it has the recommended 10" @R-38. Half of home has a flat roof with about 12" of clearance for insulation that was extremly difficult to access. Thanks to the two Steves and John they "Got her done". Also got the $600 rebate savings from SRP. We are Looking forward to lower electricity bills this summer. They were on time at 6:00 am and all cleaned-up and on their way to the next job by 8:00am. Great young men, Thanks!"

"The owner, Joe called me and gave me a quote over the phone. YES! The quote was based on my square footage and my desire to stick with the least expensive solution. The new blown-in product won't need more added as it did with the original product blown-in by a different company 10 years ago. That inferior product had a settling rate of over half! The workers were on time, made short work of the installation, let me climb the ladder to see the before, sent me photos of the after, and stuck with the original quote. Lastly, they were here within a week of my initial call and were on time. Great company and saved me more than $800 on the next lowest estimate. Highly recommend."

Kasi is a local, family-owned and operated spray foam insulation contractor. We service Phoenix, Tucson, Prescott, and northern Arizona. Two brothers, Patrick and Paul Kariniemi, founded Kasi in 2010. Prior to starting Kasi, Patrick spent ten years with a spray foam roofing company in Phoenix and Paul was an industrial construction contractor in Minnesota. Although we’ve tested nearly every foam insulation product available in Arizona, we’ve only purchased foam from a few suppliers. We have an 11-year long relationship with our injected foam manufacturer and a five year long relationship with our spray foam supplier. Since each foam insulation product has its own application characteristics, we’ve found that you have a lot fewer problems by sticking with reputable manufacturers who stand behind their products. As a result, our technicians are experts in the products they install.\n\n

Insulation questions, answered by experts

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
