No Mix is a two component, light density, one-to-one-by-volume spray-applied polyurethane foam. No Mix does not require mixing or agitation of the resin prior to application. To produce No Mix requires the use of an “A” component (ISO) and a blended “B” component (RESIN), which contains ZERO ozone-depleting blowing agents, catalysts, polyols and fire-retarding materials. No Mix is an insulation system designed for use in residential applications. Use it in lieu of more traditional forms of insulating materials such as fiberglass, cellulose or other loose-fill products. Typical areas where spray polyurethane foam is applied are exterior walls, interior walls, vented attics, unvented attic assemblies between floors, and ceilings.
