3 water vapor permeance varies with product type and thickness.
Dow chemical extruded polystyrene insulation.
Styrofoam brand insulation is the original extruded polystyrene foam insulation.
3 based on 1 25 mm thickness.
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.
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.
For dynamic loads 10 1 is suggested.
For static loads 3 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.
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.
