High Compressive Strength Insulation

Available in 40 60 and 100 psi compressive strengths.

High compressive strength insulation.

Insulation compressive strength can be a very important design consideration. High compressive strength resists damage from heavy loads. Of energy s oak ridge national laboratory ornl. Compressive stress when the compressive strength is not reached the point at which the load stress causes a 10 relative deformation of the insulation.

Target an appropriate compressive strength. Celfort and foamular insulation is 5 0 ft2 hrºf btu for 1 inch thickness or rsi 0 87 m2 ºc w for 25mm thickness according to can ulc s770 00 1 engineering applications requiring. Thermafiber rainbarrier ci high compressive insulation uses thermacrimp technology to make the highest compressive strength mineral wool continuous insulation on the market. High performance flat roof insulation for roofs.

The compressive strength of the chosen thermal insulation should be enough to bear both dead and active loads imposed by the flat roof and its use. The high moisture absorption rate of xps in real world settings is further seen in a 2012 report from the u s. Eps is a closed cell lightweight and resilient foamed plastic composed of hydrogen and carbon atoms. Using an unnecessarily high strength insulation you end up paying for something you don t really need.

The product needs to offer sufficient compressive strength for the intended application and also be capable of withstanding any demands placed on it during installation. Designed to be used behind any cladding type including combustible and open joint assemblies. The greater the compressive strength the more durable the insulation. Astm c578 types and physical properties for foamular xps 106 kb pdf foamular extruded polystyrene insulation for cold storage applications technical guide 884 kb pdf.

Moisture effective resistance against moisture mildew corrosion and rot. Foamular 400 600 1000 high compressive strength rigid foam insulation product data sheet 467 kb pdf technical bulletins. Since eps is lower cost per inch than xps and is available in a range of compressive strengths from 10 to 60 psi using it belowgrade and under slabs can save on insulation costs. High compressive strength rigid foam insulation features and benefi ts strength designed for use in high load bearing applications.

Compressive strength the point at which the load causes the insulation to yield before it reaches 10 relative deformation. Their researchers found that xps insulation installed below grade for 15 years had absorbed 67 percent or more moisture. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher.
