WHY USE THIS CORK?

100% NATURAL
CHOICE

EXPANDED INSULATION CORKBOARD IS A SUSTAINABLE MATERIAL FOR SUSTAINABLE INSULATION

100% natural industrial process

  • Only uses cork as a raw material.
  • Without additives… agglomerate of its own resins (suberin).
  • 90% of the energy consumed is biomass (a by-product of its own industrial processing).
  • Any wastage from the industrial process is 100% reusable (cork and dust granules).

Favourable impact on cork forests

  • Total area (Portugal) 735,000 hectares.
  • The cork tree produce cork every nine years (a renewable raw material).
  • Avoids soil desertification.
  • Provides local employment in the forestry sector hence prevent population desertification.
  • Important in maintaining biodiversity (unique in Europe).
  • Portuguese forests (cork oaks) trap 5 million tons of CO2 every year.

Quality control

  • Conforms to EN 13170 + EN 13172.
  • Thermal conductivity tested by the independent laboratories: CSTB (France) and LNEC (Portugal).
  • Industrial quality /Quality control by CSTB (twice annually). Other certifications (in addition to EN 13170): > MPA Stuggart – Ogo-Graf-Institut (quality verification).
  • ARGE KDR – Zertifikat no. - R0700144 “R” green 100% vegetal.
  • ACERMI by CSTB, France (Industrial and quality control).

In general

  • High level of stability… coping with major thermal variations.
  • Deals with temperatures of between: (-) 180ºC and (+) 120ºC.
  • In case of fire, cork does not release toxic gases.
  • Unlimited durability, maintaining its technical characteristics (official tests demonstrate between 45 and 50 years).
  • Totally recyclable after utilisation… It may again be reused in construction applications
