Open cell spray foam insulation provides a lower r-value per inch, but is therefore typically more affordable than closed cell spray foam insulation. A set of closed cell foam will produce roughly 4500 board feet of foam or in other words it will cover 4500 square feet one inch thick for roughly an R-7. [CDATA[// > < --!
