EPS is a lightweight cellular plastics
material consisting of small spherical shaped particles containing
about 98% air. This microcellular
closed cell construction provides EPS with excellent insulating
and shock absorbing characteristics. High strength to weight
ratio. Sheet EPS is cut from a primary block measuring 5.000m
x 1.200m x .500m thick. EPS is an inert, organic material that
will not rot. EPS is dimensionally stable after kiln drying
and will not shrink or sag over time. EPS will last the life
of buildings without physical damage. It has been used throughout
the world for over 40 years. |

The ‘K’ value or Thermal Conductivity
Specifies the rate of heat transfer in any Material. If a material
has a ‘K’ value of 1 it means a 1m cube will transfer
heat at 1 watt for every degree of temperature difference between
opposite faces. The lower the ‘K’ value the
less heat the material will transfer. Eg:
EPS Grade ‘S’..................... = 0.038 w/mK.
Fiberglass............................= 0.050 w/mK.
Plasterboard 19mm.......... = 0.225 w/mK.
Concrete.............................. = 1.250 w/mK. |
