XPS- (Extruded Polystyrene)


Extruded polystyrene is produced from polystyrene, by extrusion. It can be manufactured in the form of board in different size, edge and surface shape and with different compressive strength, according to the intented use and the place of use. It is used for thermal insulation.

XPS reduces the loss of energy used for heating and cooling of a building up to minimum (60%), provides protection of the walls from the expansion and contraction under the influence of weather conditions, does not crumble with time elapse, rot, undergo to corrosion or rust, easy to cut and apply, does not lose physical properties, provides eternal isolation of buildings. Application areas: In isolation systems against heat and cold of exterior walls, in underground and flood plain levels of isolation works, at ceiling, floor and wall works.

XPS Foamboard Production

  • It is manufactured with the licence of Owens Corning UCI USA.
  • It is produced in the plants that hold the ISO 9001 Quality Management System, ISO 14001 Environmental Management System and OHSAS 18001 Occupational Health and Safety Management System certificates provided by Bureau Veritas.
  • XPS Foamboard products that are subject to TS 11989 – 1 EN 13164, hold the CE mark according to the Construction Products Directive (89/106/EEC).

General Information

  • Its declared thermal conductivity is λ ≤ 0,035 W/mK. (at 10˚C)
  • Depending on the declared thermal conductivity values, XPS Foamboard products are in the thermal conductivity group of 035.
  • Water vapour diffusion resistance factor μ = 90 - 100.
  • The temperature of use is between -50/+75˚C.
  • It has 100% closed porous cell structure that keeps the water out.
  • It does not have a capillary absorbency.
  • It has high compressive strength.
  • Even though it is resistant to acidic and basic chemicals, it is sensitive to chimney gases, methane group gases and chemicals of gasoline group, eter, esther and amine group.
  • It is sensitive to ultra violet (UV) rays of the sun. It should be protected from direct sun light.
  • It is classfied as “E” with respect to TS EN 13501-1.
