Dow Rigid Foam Insulation R Value

Since its discovery in 1941 styrofoam brand xps insulation has a long and rich heritage as a sustainable building product insulating to meeting core thermal moisture air and vapor performance requirements through its rigid foam board technology.

Dow rigid foam insulation r value.

It provides about r 5 per inch. It is offered in multiple thicknesses and dimensions in both square edged and tongue and groove joints. 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.

1r values are consistent with criteria of astm c578 and requirements of ftc r value rule 16 cfr part 460. Shop dow r 10 common. 4based on 1 25 mm thickness. 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.

2 in x 4 ft x 8 ft. This product typically has an r value of 3 6 to 4 0 per inch of thickness. 1 when joints penetrations detailed appropriately. The higher the r value the greater the insulating power.

See also material data sheet msds 1511 or msds 1911. This material offers the highest r values about r 6 to 6 5. Dow scoreboard is scored over 16 and 24 making it. 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.

Some products have reinforced facing to make them sturdier. 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. Choose this option for areas that need a good amount of strength and water resistance.

The information on this page is based on data considered to be true and accurate based on periodic internal. It provides r values that range from 3 6 to 4 2 per inch.
