RetroFoam insulation is the best insulation for existing walls. Un-like foam insulations of the past there is little to no odor and it is 100% environmentally friendly. Without the tear out and mess of de-construction, RetroFoam can be injected into the stud cavity of the wall, giving an R-4.7 per inch of thickness. Instead of weeks your home can be well insulated in about one or two days with little to no visible traces.

Polymaster's R501 is a new-generation, vastly-superior alternative to traditional urea-formaldehyde foams (known for their odor). It is odor-free as well as non-toxic.
R501 foam insulation is a cost-effective, environmentally green, thermal and acoustical insulation designed for use in concrete block walls and cavities in commercial stuctures.

R501 is pressure-injected into masonry through 5/8" holes drilled directly into the wall. When injected, R-501 foam flows into and fills cavities, up to 12 feet vertically from the insertion hole.
R501 yields R-4.6 per inch, equivalent to R-11.05 when injected into walls constructed of 105 lb density concrete blocks (CMUs).
