Styrofoam brand scoreboard insulation is an extruded polystyrene foam insulation board that is easy to cut to commonly used widths.
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.

As insulators pink and blue boards perform virtually identically with an insulating value of r 5 per inch of thickness.
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.
Products with foil facing help the panels resist moisture vapor.
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.
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.
Specially designed and formulated insulation products from dow are available to help meet specific application needs.
Choose this option for areas that need a good amount of strength and water resistance.
Foamular 250 retards the transmission of water vapor and moisture in masonry walls.
For example styrofoam wallmate extruded polystyrene insulation with slotted vertical edges is installed with furring strips and covered with gypsum board for a finished appearance.
It provides about r 5 per inch.
This material offers the highest r values about r 6 to 6 5.
Dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps.
