Providing much higher r values than a standard rhino board ceiling.
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.
Insulating boards are just one of the many types of foam insulation.
Due to its special characteristics it is the ideal solution for inverted ballasted systems and utility roof decks.
Various insulation material thermal conductivity chart.
The thermal performance of these polystyrene sheets is unparalleled to other insulators.
The studs conduct more heat than the insulation between them.
Xps can also be used in exposed roofing systems.
Ranges are marked with.
This also gives it strength making it rigid.
Isoboard is the name of the insulation product.
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 is measured according to en 12667.
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.
Extruded polystyrene xps xps is a thermal insulation board produced from polystyrene in an extrusion process.
Thermal conductivity of expanded polystyrene.
Through special process the hard expanded board is extruded.
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.
Insulation material thermal conductivity chart.
Isoboard is a high quality rigid extruded polystyrene foam insulation manufactured in south africa.
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.
Consider using spray foam insulation as well to seal smaller cracks and gaps.
