They sport an r value of 6 0 8 0 per inch of insulation about double their open cell foam counterparts.
Closed cell spray foam r value per inch. The r value is r 3 5 to r 3 6 per inch so filling a 2 4 cavity yields about an r 13. For example closed cell spray foam depending on brand can offer an r 6 or r 7 per inch. Closed cell foam r6 r8. Closed cell spray foam insulation.
Ideal for continuous insulation solutions. For advanced temperature control superior moisture resistance and added structural support sealtite pro s higher density spray foam products deliver results. Open cell spray foam has an r value of about r 3 7 per inch while closed cell spray foam has an r value that may be as high as r 6 5 per inch. Higher r value per inch easier to accommodate high r value requirements in narrow spaces.

Two inches of closed cell foam will provide r12 r14 of insulation. With an even tighter seal and higher r value per inch closed cell spray foam is ideal for residential commercial and industrial projects. The open cell structure of low density foam insulation means the r value is lower than its closed cell counterpart. Closed cell spray foam is the most expensive residential insulation available.
