Dow Rigid Foam Insulation R Value

Expanded polystyrene insulation is similar to the foam used for packing peanuts and it s typically used for insulated concrete forms also knows as icf s.

Dow rigid foam insulation r value.

1r values are consistent with criteria of astm c578 and requirements of ftc r value rule 16 cfr part 460. 2 in x 4 ft x 8 ft. Because rigid foam plastic insulation products are not all aged in accordance with the same standards it is useful to publish comparison r value data. 2 r means resistance to heat flow.

This product typically has an r value of 3 6 to 4 0 per inch of thickness. Choose this option for areas that need a good amount of strength and water resistance. 1 when joints penetrations detailed appropriately. See also material data sheet msds 1511 or msds 1911.

It is offered in multiple thicknesses and dimensions in both square edged and tongue and groove joints. The information on this page is based on data considered to be true and accurate based on periodic internal. It is lightweight and easy to use and provides an optimum balance between performance and cost. This material offers the highest r values about r 6 to 6 5.

R values vary depending on many factors including the mean temperature at which the test is conducted and the age of the sample at the time of testing. Insulfoam rigid foam is a high performance built to spec sheathing insulation that provides superior r value and moisture resistance. The higher the r value the greater the insulating power. It provides about r 5 per inch.

2 stated thermal resistance values are based upon conditioning requirements and test methodology found in astm c1289 and astm c518 for foil faced polyisocyanurate insulation. Thermosetting resins from dow can be used as an alternative to traditional formaldehyde based resins for binding mineral fibers in the production of insulation blanket products that go into building insulation systems and specialty insulation. Shop dow r 10 common. Some products have reinforced facing to make them sturdier.

It provides r values that range from 3 6 to 4 2 per inch. 4based on 1 25 mm thickness.
