Polystyrene Insulation Board Thermal Conductivity

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.

Polystyrene insulation board thermal conductivity.

Consider using spray foam insulation as well to seal smaller cracks and gaps. Xps can also be used in exposed roofing systems. Thermal conductivity is measured according to en 12667. Providing much higher r values than a standard rhino board ceiling.

This eliminates thermal bridging which is the energy lost through wall studs. Heat transfer engineering. Typical values range from 0 032 to 0 038 w m k depending on the density of the eps board. The thermal performance of these polystyrene sheets is unparalleled to other insulators.

It is manufactured with microscopic gas filled cells which resemble a honeycomb. Ranges are marked with. Due to the thermal conductivity of foam this insulation is the best protection for your home against cold. Insulating boards are just one of the many types of foam insulation.

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. Thermal conductivity is defined as the amount of heat in watts transferred through a square area of material of given thickness in metres due to a difference in temperature the lower the thermal conductivity of the material the greater the material s ability to resist heat transfer and hence the greater the insulation s effectiveness. Isoboard is the name of the insulation product. Extruded polystyrene xps xps is a thermal insulation board produced from polystyrene in an extrusion process.

The eps specifically can resist moisture and cold leaving your home warm during winter. The panels provide a continuous energy efficient surface. Extruded polystyrene thermal conductivity. 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.

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. Various insulation material thermal conductivity chart. Through special process the hard expanded board is extruded. This also gives it strength making it rigid.

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. Thermal conductivity of expanded polystyrene. R values per inch given in si and imperial units typical values are approximations based on the average of available results. Xroof roof insulation boards are ideal for a multitude of roofing requirements inc.

Insulation material thermal conductivity chart. Huamei brand extrusion and expanded polystyrene xps thermal insulation boards are made with polystyrene.
