Insulating Exterior Plaster Achieves R-5 Per Inch
Fixit 222 is a lime plaster to which granulized silica aerogel has been added. It can be sprayed or troweled onto a wall and then coated with a harder surface plaster to provide a stucco cladding that can be fully exposed to the elements. While standard portland cement plasters provide very low R-values (considerably less than R-1 per inch), Fixit 222 provides R-5.15 per inch (0.028 W/mK).
