Stucco Application

An insulating solution for every wall.

Wood framing (studs, window and door framing, and headers) makes up about 25% of the wall surface. Insulating only the cavities means 25% of the wall surface is left uninsulated. A continuous layer of STYROFOAM™ extruded polystyrene or polyisocyanurate insulation applied on the exterior of the wall reduces energy loss. And, it can reduce the potential for condensation and resulting moisture problems in your walls.

There's a Dow insulation solution that's right for every Stucco application:
