Extruded Polystyrene Foam Board Compressive Strength

Styrofoam is the trade name of a range of blue extruded polystyrene foam insulation boards originally developed and marketed by the dow chemical company in the early 1940 s.

Extruded polystyrene foam board compressive strength.

Extruded polystyrene is a closed cell polystyrene rigid foam board with high compressive strength and excellent long term thermal resistance performance. Polystyrene blocks are used in construction as permanent insulation in buildings. Product data sheet foamular 400 600 1000 extruded polystyrene xps rigid foam insulation energy saving1 moisture resistant xps insulation high compressive strength foamular 400 xps insulation. Foamular extruded polystyrene xps insulation astm c578 types and physical properties this table outlines the basic physical property requirements of astm c5781 and foamular xps insulation compliance.

Compressive and flexural strength values for expanded polystyrene are based on short term load conditions in accordance with typical astm test standards. Unlike expanded polystyrene eps styrofoam is manufactured via a continuous extrusion process. 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. As do most load bearing building materials eps foam insulation products creep under long term continuous load conditions and in critical applications this characteristic must be considered.

The products are organized left to right in ascending compressive strength. Celfort and foamular extruded polystyrene insulation boardsare suitable for all types of high strength construction applications the boards are lightweight durable and impact resistant which helps to reduce job site damage foam insulation can be scored and fabricated easily with common hand tools. Ceiling boards xps.

It is produced on a continuous fully automated extrusion process. Extruded polystyrene xps rigid foam insulation owens corning foamular 250 extruded polystyrene xps rigid foam insulation is a closed cell highly moisture resistant rigid foam board well suited to meet the needs for a wide variety of residential and commercial construction applications. Astm c578 type vi. Extruded polystyrene is a closed cell polystyrene rigid foam board with high compressive strength and excellent long term thermal resistance performance due to its inherent resistance to moisture transfer.

2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. For static loads 3 1 is suggested. Polystyrene blocks eps.
