Polystyrene Insulation Board Thermal Conductivity

Thermal conductivity of expanded polystyrene.

Polystyrene insulation board thermal conductivity.

The studs conduct more heat than the insulation between them. The thermal performance of these polystyrene sheets is unparalleled to other insulators. There is a sealed and foamed structure which is an environmental protection material with the performances of high resist compression waterproof moisture proof air proof. Thermal conductivity is measured according to en 12667.

R values per inch given in si and imperial units typical values are approximations based on the average of available results. Insulation material thermal conductivity chart. The thermtest heat flow meter hfm is a steady state heat transfer system measuring the thermal conductivity and thermal resistivity of flat slab insulating materials such as foams solids and textiles figure 3. Typical values range from 0 032 to 0 038 w m k depending on the density of the eps board.

Through special process the hard expanded board is extruded. Isoboard is the name of the insulation product. Consider using spray foam insulation as well to seal smaller cracks and gaps. Extruded polystyrene thermal conductivity.

This eliminates thermal bridging which is the energy lost through wall studs. Huamei brand extrusion and expanded polystyrene xps thermal insulation boards are made with polystyrene. The hfm measures thermal conductivity over a range of 0 005 to 0 5 w m k and over a temperature range of 20 c to 70 c in accordance. The panels provide a continuous energy efficient surface.

Various insulation material thermal conductivity chart. Isoboard is a high quality rigid extruded polystyrene foam insulation manufactured in south africa. Heat transfer engineering. Insulating boards are just one of the many types of foam insulation.

The value of 0 038 w m k was obtained at 15 kg m 3 while the value of 0 032 w m k was obtained at 40 kg m 3 according to the datasheet of k 710 from styrochem finland. Due to the thermal conductivity of foam this insulation is the best protection for your home against cold. Providing much higher r values than a standard rhino board ceiling. Extruded polystyrene xps xps is a thermal insulation board produced from polystyrene in an extrusion process.

Ranges are marked with. Due to its special characteristics it is the ideal solution for inverted ballasted systems and utility roof decks. 50mm cellecta hexatherm xroof 300l is an extruded polystyrene thermal insulation board designed specically for inverted roof applications where a high resistance to compression and water absorption is essential. It is manufactured with microscopic gas filled cells which resemble a honeycomb.

Xroof roof insulation boards are ideal for a multitude of roofing requirements inc. Xps can also be used in exposed roofing systems.
