Dow Chemical Extruded Polystyrene Insulation

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.

Dow chemical extruded polystyrene 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 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.

3 based on 1 25 mm thickness. For dynamic loads 10 1 is suggested. Values are based on the desiccant method and they apply to insulation 1 in thickness. 3 based on 1 25 mm thickness.

3 water vapor permeance varies with product type and thickness. With more than 60 years of proven performance in wet environments the. For dynamic loads 10 1 is suggested. 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.

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. Its dense closed cell structure gives styrofoam brand extruded polystyrene foam insulation excellent moisture resistance long term thermal performance and compressive strength. For static loads 3 1 is suggested.

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. 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.
