Closed Cell Spray Foam R Per Inch

For more comfortable and consistent indoor temperature control and optimum energy efficiency sealtite pro s open cell spray foam products are the natural choice.

Closed cell spray foam r per inch. With foamed in place insulation it is relatively easy though not inexpensive to fill wall and ceiling cavities completely. All these have r values ranging from r 3 2 to r 3 8 per inch. Closed cell foam has a higher r value than open cell foam usually about 6 0 per inch. This higher rating makes closed cell foam better at keeping heat in or out of a structure.

Both closed cell spray foam and open cell spray foam insulation can be used effectively in commercial building designs to allow the building to achieve energy efficiency and consistent performance. If you want to install spray foam in a stud wall and price is no object then it would seem to make sense to specify closed cell spray foam right. 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. When applied on the interior open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior.

Just like for open cell foam r values are additive. If you want to install spray foam in a stud wall and price is no object then it would seem to make sense to specify closed cell spray foam right. Most spray polyurethane foam is called two component foam. The r value of closed cell foam is r 6 5 7 per inch.

Innovations such as icynene proseal le allows for an initial pass of five inches 5 to achieve r 35. Closed cell spray foams are between 2 and 4 lbs. Closed cell insulation products such as icynene proseal allow builders and architects the ability to achieve r 21 in a three inch pass. That means if you used foam it green closed cell which is r 7 per inch it s r value for a 3 5 deep wall cavity would be r 24 5.
