High compressive strength insulation.

The high moisture absorption rate of xps in real world settings is further seen in a 2012 report from the u s. Available in 40 60 and 100 psi compressive strengths. High compressive strength resists damage from heavy loads. High performance flat roof insulation for roofs.

The greater the compressive strength the more durable the insulation. Designed to be used behind any cladding type including combustible and open joint assemblies. Using an unnecessarily high strength insulation you end up paying for something you don t really need. Moisture effective resistance against moisture mildew corrosion and rot.

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. Target an appropriate compressive strength. 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. Compressive strength the point at which the load causes the insulation to yield before it reaches 10 relative deformation.

Of energy s oak ridge national laboratory ornl. 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. 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. Their researchers found that xps insulation installed below grade for 15 years had absorbed 67 percent or more moisture.

The mechanical strength of eps varies with its density. The most important mechanical property of eps insulation and building products is its resistance to compressive stresses which increase as the density becomes higher. High compressive strength material can resist damage by foot traffic vibration and various forms of external pressure. Thermafiber rainbarrier ci high compressive insulation uses thermacrimp technology to make the highest compressive strength mineral wool continuous insulation on the market.

Eps is a closed cell lightweight and resilient foamed plastic composed of hydrogen and carbon atoms. High compressive strength long term thermal performance hydrophobic insulation closed cell structure no food value for rodents.
