Dow Foam Board Insulation R Value

2 r means resistance to heat flow.

Dow foam board insulation r value.

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. 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. 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. The higher the r value the greater the insulating power. Blue board can be used both on exterior and interior walls to give you a continuous insulation barrier that can increase effective r value of the wall by up to 20. Shop dow r 10 common.

Value at yield or 5 whichever occurs first. R value determined by astm c518. 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. 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.

Each type comes with unique advantages. 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. Data ranges from 0 00 to value shown due to the level of precision of the test method.

Choose from three types of insulating foam core boards for wall insulation. Expanded polystyrene foam eps is the cheapest and least used foam board product on the market. Dow styrofoam insulation blue board dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps.
