Styrofoam extruded polystyrene and polyisocya nurate insulations from dow are the only rigid insulation products built on the scientific expertise of the dow chemical company a leading global supplier of chemical plastic and agricultural products and services.
Dow chemical extruded polystyrene insulation.
Since styrofoam brand extruded polystyrene foam insulations are visco elastic materials adequate design safety factors should be used to prevent long term creep and fatigue deformation.
With more than 60 years of proven performance in wet environments the.
3 based on 1 25 mm thickness.
Its dense closed cell structure gives styrofoam brand extruded polystyrene foam insulation excellent moisture resistance long term thermal performance and compressive strength.
Since styrofoam brand extruded polystyrene foam insulations are visco elastic materials adequate design safety factors should be used to prevent long term creep and fatigue deformation.

Dow has manufactured styrofoam brand extruded polystyrene foam insulation for use in construction and specialty applications for more than 60 years.
Values are based on the desiccant method and they apply to insulation 1 in thickness.
Styrofoam brand insulation is the original extruded polystyrene 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.
