Keep Your Phoenix-Area Home More Comfortable with Foam Insulation

If your home never seems to cool down, your air conditioner runs all day, or some rooms are always hotter than others, your insulation could be part of the problem.

Since 2010, KASI has helped homeowners across Phoenix, Tucson, Maricopa, Prescott, Flagstaff, Sedona, and the surrounding communities solve this with RetroFoam injection foam and spray foam insulation. Both create a sealed barrier that stops hot air from seeping into your walls and attic, so your HVAC doesn’t have to work as hard to keep up. Whether you’re upgrading an older home or insulating new construction, we’ll assess your specific situation and recommend a solution tailored to your needs.

Helping Arizona Homes Stay More Comfortable

Arizona’s desert climate is demanding on homes. Long summers, intense sunshine, and extreme temperatures can make it difficult to keep your home consistently comfortable.

KASI provides two professional insulation solutions designed to help reduce unwanted air leaks and improve indoor comfort:

  • RetroFoam injection foam insulation for most existing homes
  • Spray foam insulation for attics, basements, new construction, remodels, garages, additions, and other open-wall projects

We proudly serve homeowners throughout Phoenix, Tucson, Maricopa, Prescott, Flagstaff, Sedona, and surrounding Arizona communities.

Does Your Home Feel Miserable?

If you’re constantly adjusting the thermostat but your home still feels uncomfortable, you’re likely paying for cooling that’s leaking right back out.

Many Arizona homeowners experience:

  • Hot upstairs areas or bonus rooms
  • Spots that never seem to cool down
  • An air conditioner that runs almost nonstop
  • Uneven temperatures throughout the house
  • Rising cooling costs during Arizona summers
  • Older block or stucco homes that struggle to stay comfortable

These issues often point to unwanted air movement and insulation that isn’t performing the way it should.
