Phoenix Block Insulation

Stop Drafting By Filling Every Void

Drafting - uncontrolled airflow - is a major source of energy loss in many homes.  Many times drafts cannot be felt because they are so small, but the combination of all drafts in a home is often compared to leaving a window open all year round.  On many old block homes, builders intentionally left gaps in the grout to facilitate airflow for evap coolers.  As the video to the left shows, Retrofoam fills every cavity and crevice in the wall cavity - blocking drafts, insects, and dust intrusion.

Save Money And Increase Comfort

A block home with foam insulation slows heat/cold transfer through the wall by 82% when compared to a home with out foam insulation.  AC units and heat pumps run less and the home maintains more consistent temperature.  Homeowners with Retrofoam in their walls enjoy a more comfortable home and lower utility bills.  See video testimonials from Retrofoam of Arizona customers here.

Increase R Value

Many older block homes have R 30 - R 50 of insulation in the attic, yet their walls are only R 2.  A Retrofoam injection will increase the R value of the entire block wall from R 2 to R 11.05.  All without disturbing the interior of the home or causing harmful off gassing into the home.
