Dow Rigid Foam Insulation R Value

Insulfoam rigid foam is a high performance built to spec sheathing insulation that provides superior r value and moisture resistance.

Dow rigid foam insulation r value.

Some products have reinforced facing to make them sturdier. It is offered in multiple thicknesses and dimensions in both square edged and tongue and groove joints. This product typically has an r value of 3 6 to 4 0 per inch of thickness. It is lightweight and easy to use and provides an optimum balance between performance and cost.

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. See also material data sheet msds 1511 or msds 1911. The information on this page is based on data considered to be true and accurate based on periodic internal. 1r values are consistent with criteria of astm c578 and requirements of ftc r value rule 16 cfr part 460.

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. 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. It provides about r 5 per inch. Shop dow r 10 common.

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. Dow scoreboard is scored over 16 and 24 making it. This material offers the highest r values about r 6 to 6 5. 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.

Choose this option for areas that need a good amount of strength and water resistance. The higher the r value the greater the insulating power.
