Dow Polystyrene Insulation Board

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.
Dow polystyrene insulation board. Working with home insulation boards. 2 in x 4 ft x 8 ft. Choose this option for areas that need a good amount of strength and water resistance. Styrofoam brand scoreboard extruded polystyrene foam insulation is an extruded polystyrene foam insulation board that is scored longitudinally on 16 and 24 centers making it easy to size to commonly used widths cut and install.
It provides about r 5 per inch. Foamular 250 retards the transmission of water vapor and moisture in masonry walls. 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. 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.
Has excellent insulating characteristics high resistance to water and water vapor exceptional compressive strength and long term durability. Products with foil facing help the panels resist moisture vapor. This material offers the highest r values about r 6 to 6 5. As insulators pink and blue boards perform virtually identically with an insulating value of r 5 per inch of thickness.
Foamular 250 extruded polystyrene xps provides continuous insulation in insulated concrete sandwich panel walls in masonry unit cavity walls or when used with non penetrating surface mounted furring systems over masonry or concrete walls. Dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps. Pink and blue rigid foam insulation boards are made from polystyrene resin that is melted and then forced through a die to form it into the desired shape. It is especially recommended for exterior cavity walls and foundations.
Styrofoam brand scoreboard insulation is an extruded polystyrene foam insulation board that is easy to cut to commonly used widths.
