WHY SHOULD WE USE EXPANDED INSULATION CORK IN CONSTRUCTION?
- Favorable impact on cork forests
- 100% natural industrial process
- Technical characteristics:
> Density: 100/120Kg/m³.
> Thermal conductivity: test results range between 0.036/0.038 W/mk.
> Value declared for EU label: 0.040W/mk.
> Resistance to compression at 10%: declared 100 KPa (test results 110/120 KPa) – EN 826.
>Perpendic
ular face resistance: declared TR50 (test results 60 KPa) – EN 1607.
> Level of humidity: maximum 8% - EN 1215.
> Water absorption: declared 0.5 Kg/m² (maximum test result 0.3 kg /m²) – EN 1609. > Longitude tolerance: between +/- 3 and 5mm – EN 822.
> Thickness tolerance: between +/- 1 y 2 mm – EN 823.
> Fire resistance: Euro class “E” – EN 13501 – 1.
> Durability: practically unlimited.
> Recyclable: 100%.
> Impact noise: 20dB LF - 40 dB MF - 30dB HF.
> Air noise: 30dB LF - 35 dB MF - 34dB HF.
> 50mm Sound absorption: 40% at 400 Hz / 50 Hz to 3500%
> Sound speed on cork: 500 m / second.
> Sound absorption coefficient 500 CPS: 0.33/0.35.
- 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 aoer utilisation… It may again be reused in construction applications.
