High Compressive Strength Insulation

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 insulation.

Their researchers found that xps insulation installed below grade for 15 years had absorbed 67 percent or more moisture. 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. 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.

Of energy s oak ridge national laboratory ornl. Insulation compressive strength can be a very important design consideration. Foamular 400 600 1000 high compressive strength rigid foam insulation product data sheet 467 kb pdf technical bulletins. Compressive stress when the compressive strength is not reached the point at which the load stress causes a 10 relative deformation of the insulation.

Compressive strength the point at which the load causes the insulation to yield before it reaches 10 relative deformation. Designed to be used behind any cladding type including combustible and open joint assemblies. 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. The mechanical strength of eps varies with its density.

High performance flat roof insulation for roofs. High compressive strength resists damage from heavy loads. High compressive strength long term thermal performance hydrophobic insulation closed cell structure no food value for rodents. The greater the compressive strength the more durable the insulation.

Available in 40 60 and 100 psi compressive strengths. Eps is a closed cell lightweight and resilient foamed plastic composed of hydrogen and carbon atoms. High compressive strength material can resist damage by foot traffic vibration and various forms of external pressure. Using an unnecessarily high strength insulation you end up paying for something you don t really need.

Thermafiber rainbarrier ci high compressive insulation uses thermacrimp technology to make the highest compressive strength mineral wool continuous insulation on the market. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher. The high moisture absorption rate of xps in real world settings is further seen in a 2012 report from the u s.
