Dow Blue Rigid Foam Insulation

Easy to work with rigid insulation can be incorporated into construction or added later to increase r value.

Dow blue rigid foam insulation.

Dow styrofoam insulation blue board is a nonstructural rigid board insulation manufactured of extruded polystyrene foam xps. 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. Compressive strength 40 psi. That s understandable since the heating and cooling bill.

Both are closed cell foam products. Dow 1643 blue styrofoam se extruded polystyrene foam square edge xps insulation closed cell r 20 30 psi 4 inch x 4 x 8 foot square edge. 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. Rigid insulation comes in panels of various thickness which provide different r values.
