Spray Urethane Foam Insulation
There are several types of Polyurethane foam insulation with different compositions and chemical formulation, but the two major categories are: open cell spray foams and the closed cell spray foams.
Open cell spray foam insulation
R 3.8/inch = R 13 total
The open cell spray foam has a similar R value to other insulation forms but in addition to the R value, the open cell spray Foam insulation is air sealed, meaning that it creates an air barrier and you would not need to take any further measures to prevent air leaks into your building when you are using open cell spray foam in Boston weather. It creates a very tight building envelope and the fact that you don’t need any extra insulation measures with it justifies the extra cost of spray foam insulation material.
