Dow Foam Board Insulation R Value

1r values are consistent with criteria of astm c578 and requirements of ftc r value rule 16 cfr part 460.

Dow foam board insulation r value.

For insulated panels and boards we offer polyurethane systems that are lightweight increase energy efficiency improve longevity and meet the most demanding industry requirements. For polyurethane pur and polyisocyanurate pir foam insulation systems our high performance surfactants boost energy efficiency. Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. Choose from three types of insulating foam core boards for wall insulation.

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. Shop dow r 10 common. 2 in x 4 ft x 8 ft. Each type comes with unique advantages.

Data ranges from 0 00 to value shown due to the level of precision of the test method. This product typically has an r value of 3 6 to 4 0 per inch of thickness. 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. The r value at 180 day real time age and 75ºf mean temperature is commonly used to compare products and is the value printed on the product.

4based on 1 25 mm thickness. Expanded polystyrene foam eps is the cheapest and least used foam board product on the market. Values at yield or 10 deflection whichever occurs first. The higher the r value the greater the insulating power.

2 r means resistance to heat flow. R value determined by astm c518. Dow styrofoam insulation blue board dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps.
