The higher density not only allows for it to be molded for decorative or light structural uses it also provides r values of about 6 0 per inch.

Open cell spray foam r value.

Most open cell foam has a density of about 5 pounds per cubic foot. Closed cell spray foam has a far better r value per inch than other less effective insulations like cellulose fiberglass or even open cell foam. The r value for open cell is typically around 3 7 at 1 thick and varies by manufacture. 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.

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. It has a lower r value per inch than closed cell foam and is vapor permeable. 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.

A foams r value is its resistance to heat flow or in other words how well they insulate. 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. Closed cell foam can be made with densities as high as 1 7 to 2 0 lbs cu. Ft with an r value insulation factor of about 3 5 per inch.

Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more. 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. 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. Closed cell spray foam insulation is vapor and air impermeable and is applied with a minimum of 2 on average with use on on interior and exterior building applications.

Closed cell spray foams are between 2 and 4 lbs. Two inches of closed cell foam will provide r12 r14 of insulation. Open cell foam weighs between 0 4 and 0 5 lbs cu. Just like for open cell foam r values are additive.

They sport an r value of 6 0 8 0 per inch of insulation about double their open cell foam counterparts. It performs much better than any form of batt for stopping air flow but it is not as complete of an air seal as closed cell spray foam. Open cell spray foam typically has an r value of 3 5 per inch and it should be noted that open cell does not form a tight air seal. Closed cell spray foam provides a higher r value per inch 6 5 than less expensive insulation types like cellulose and fiberglass 3 5 to 3 7.

Closed cell spray foam insulation. Closed cell foam has a higher r value than open cell foam usually about 6 0.
