Dow Chemical Extruded Polystyrene Insulation

3 water vapor permeance varies with product type and thickness.

Dow chemical extruded polystyrene insulation.

3 based on 1 25 mm thickness. For static loads 3 1 is suggested. Values are based on the desiccant method and they apply to insulation 1 in thickness. Styrofoam brand square edge insulation is an extruded polystyrene foam xps insulation board that meets the needs of the commercial foundation and building floor slab market and can also be used for attics foundations slabs and crawl spaces in residential applications.

For static loads 3 1 is suggested. For dynamic loads 10 1 is suggested. 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. For dynamic loads 10 1 is suggested.

With more than 60 years of proven performance in wet environments the. 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. Its dense closed cell structure gives styrofoam brand extruded polystyrene foam insulation excellent moisture resistance long term thermal performance and compressive strength. Styrofoam brand insulation is the original extruded polystyrene foam insulation.

Since its discovery in 1941 styrofoam brand xps insulation has a long and rich heritage as a sustainable building product insulating to meeting core thermal moisture air and vapor performance requirements through its rigid foam. For dynamic loads 10 1 is suggested. 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. 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.

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. For static loads 3 1 is suggested.
