Summit Builders Group offers the water blown open cell insulation which comes in convenient 5 gal pails because they are easy to transport, manage and dispose of. This air sealant is designed specifically for use by the patented Spray Pod Tornado, a portable two component spray systems. Open cell spray insulation would be a good choice where larger framing sizes need the greatest R-value per inch possible.
Spray insulation is a less dense than other types of closed cell foam. It has a larger, less compact cell structure. It can be an air barrier as well as a water vapor barrier if it is sprayed at the correct thickness. It is often used in maintenance projects or other outdoor applications, but can be used anywhere where building performance needs improvements, but small enough to need just spray insulation in 5 gallon pails.
