Soy Spray Foam Insulation R Value Per Inch

R values are additive so you can multiple the number of inches of insulation thickness times the r value to arrive at a total insulation value.

Soy spray foam insulation r value per inch.

For example closed cell spray foam depending on brand can offer an r 6 or r 7 per inch. Eco spray foam insulation. For example blown fiberglass typically has an r value of only r 2 to r 3 per inch depending on compression density and moisture. Why spray foam insulation is so effective in meeting code requirements is that it has a higher r value per inch of product used than batts.

One manufacturer urethane soy systems co. According to green building advisor. However there are open cell spray foam insulation products actually offer r 3 7 per inch such as icynene classic and. 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.

It has an r value. Soy based insulation comes in open cell foam and closed cell foam. According to industry publication fine home building the r value for open cell spray foam is between r 3 5 r 3 6 per inch. The latter has a higher r value per inch.

Rigid foam soy insulation is new on the market as well. The closed cell spray foam stops air infiltration and provides about an r 5 per inch. Homes generally try and reach an r value of 38 with their insulation. All these have r values ranging from r 3 2 to r 3 8 per inch.

The r value of. The higher the r value of an insulation product the more effective the insulation properties. Products with a higher r value provide greater insulation. Made with plant based products such as soy eco spray foam is more eco friendly.

A higher r value prevents more heat from escaping through the insulation. A typical 2 4 stud filled with open cell spray foam will have an r value. The r value of spray foam insulation is approximately 6 per inch so those using spray foam as their insulator will need about 6 3 inches of thickness to reach r 38. The higher the number the better the material insulates.

R value measures how a material resists heat transfer. Volga s d touts its soy therm as having a density of 1 2 pound per cubic foot of rigid foam insulation. Open cell spray foams are between 5 and 1 lbs per cubic foot and have an r value of 3 0 4 0 per inch of insulation. Open cell foam is impermeable to air and permeable to moisture.

R value is the term given to thermal resistance to heat flow. The r value is r 3 5 to r 3 6 per inch so filling a 2 4 cavity yields about an r 13. Focusing on spray foam insulation materials there is a difference between the two main types. Insulate rim joists and other large areas with this product meant for big jobs.
