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.




R501 being injected

R501 logoPolymaster'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 in a concrete block

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).
