Polystyrene Insulation Board Thermal Conductivity

Insulating boards are just one of the many types of foam insulation.

Polystyrene insulation board thermal conductivity.

Xps can also be used in exposed roofing systems. Isoboard is the name of the insulation product. Various insulation material thermal conductivity chart. Heat transfer engineering.

Through special process the hard expanded board is extruded. Thermal conductivity of expanded polystyrene. 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. The studs conduct more heat than the insulation between them.

This eliminates thermal bridging which is the energy lost through wall studs. Ranges are marked with. This also gives it strength making it rigid. 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.

Typical values range from 0 032 to 0 038 w m k depending on the density of the eps board. 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. Due to the thermal conductivity of foam this insulation is the best protection for your home against cold. Extruded polystyrene thermal conductivity.

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. R values per inch given in si and imperial units typical values are approximations based on the average of available results. The thermal performance of these polystyrene sheets is unparalleled to other insulators.

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. Providing much higher r values than a standard rhino board ceiling. Due to its special characteristics it is the ideal solution for inverted ballasted systems and utility roof decks. 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.

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. Thermal conductivity is measured according to en 12667. Huamei brand extrusion and expanded polystyrene xps thermal insulation boards are made with polystyrene.

Consider using spray foam insulation as well to seal smaller cracks and gaps. Extruded polystyrene xps xps is a thermal insulation board produced from polystyrene in an extrusion process.
