Just like for open cell foam r values are additive.

Closed cell foam r value 2x4 wall.

This combination ensures that the insulation is neither too loose nor too tightly packed within the walls. It s made of environmentally sound closed cell polyisocyanurate foam bonded to a durable white matte non glare aluminum facer and a reflective reinforced aluminum facer. Additional r value for a masonry wall constructed using these materials needs to add the insulating value of additional wall components typically included such as 1 solid foam polyisocyanurate r 8 extruded polystyrene r 5 expanded polystyrene r 4 or 1 of perlite r 2 7 and for an exterior air film winter no wind r 0 17 an interior. 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.

Spray foam insulation r value. Closed cell foam r6 r8. The higher the density of the foam the higher the r value per inch. Insulation is rated in two ways r value and u value.

Closed cell spray foams are between 2 and 4 lbs. How to achieve r 21 in a 2x4 wall. R 3 2 polyisocyanurate rigid foam insulation board r matte plus 3 thermasheath 3 is rigid foam r matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation board. They sport an r value of 6 0 8 0 per inch of insulation about double their open cell foam counterparts.

Closed cell foam also adds to the structural strength of a ceiling wall or roof because of its density and glue like adherence. 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. Two inches of closed cell foam will provide r12 r14 of insulation. Use r 19 or r 21 kraft faced fiberglass insulation for two by six 2x6 walls.

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 is the best choice for robust insulating where space is an issue as it can achieve 2x the r value of open cell inside a standard wall. The r value is a calculation which measures the flow of heat through an insulation product or its. Best insulation for 2x4 and 2x6 wall studs.

This is very important in situations where your code requires an r 21 for the wall but you only have a 2 4 stud because closed cell spray foam is the only way you would achieve the required r value to meet code.
