1/4 UNDERLAY INS BOARD 2 SQ BLD

Extruded polystyrene foam insulation like STYROFOAM Brand Residential Sheathing is inherently resistant to moisture, which can wreak havoc on other building materials. Moisture can compromise the performance of cavity insulation and damage drywall, wood framing and OSB or plywood sheathing. STYROFOAM Brand Residential Sheathing provides a one-two punch against moisture. Defends against wind-driven moisture penetrating a wall system, providing an effective layer of protection for wood components and cavity insulation. Moderates temperature in the wall cavity, reducing the potential for damaging moisture condensation to accumulate inside the wall cavity. Air infiltration is the largest single cause of energy loss in most homes. Adding STYROFOAM Brand Residential Sheathing to an exterior wall helps cover seams in the sheathing and gaps around windows and doors, providing a more complete barrier against air leakage.
