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.
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.
It is especially recommended for exterior cavity walls and foundations.
Choose this option for areas that need a good amount of strength and water resistance.
It provides about r 5 per inch.
Working with home insulation boards.
Products with foil facing help the panels resist moisture vapor.
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.
