Dow Foam Board Insulation R Value

Dow styrofoam insulation blue board dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps.

Dow foam board insulation r value.

Values at yield or 10 deflection whichever occurs first. 2 in x 4 ft x 8 ft. R value determined by astm c518. 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. Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. This product typically has an r value of 3 6 to 4 0 per inch of thickness. Since styrofoam brand extruded polystyrene foam insulations are visco elastic materials adequate design safety factors should be used to prevent long term creep and fatigue deformation.

For insulated panels and boards we offer polyurethane systems that are lightweight increase energy efficiency improve longevity and meet the most demanding industry requirements. 2 r means resistance to heat flow. 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. The higher the r value the greater the insulating power.

Value at yield or 5 whichever occurs first. Each type comes with unique advantages. 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. Expanded polystyrene foam eps is the cheapest and least used foam board product on the market.

Shop dow r 10 common. For polyurethane pur and polyisocyanurate pir foam insulation systems our high performance surfactants boost energy efficiency. Data ranges from 0 00 to value shown due to the level of precision of the test method.
