Insulation ~ Cork

Category: insulation September 28th, 2008 by mbc

You knew there was a use for cork except for sealing wine bottles…

Cork is a natural and effective insulator. One disadvantage for the UK builder is the need to import cork from countries with the climate to grow it such as Portugal and other Mediterranean countries (China and India are now getting in on the act). Cork is fire-retardant, resists mold and is non-toxic.



  • Biodegradable.
  • Renewable.
  • Low embodied energy.
  • Excellent acoustic insulation.
  • Low impact production – few chemical additives.
  • Self-supporting. Cork boards do not slump and therefore maintain their structure and insulating properties over time.

Cork boards at 120 kgs/m2 have a thermal conductivity or K value of 0.04 W/m.K.
(Watts per meter Kelvin ~ a lower value is a better result)

As production is still relatively small scale, cost is relatively high – I guess! I’m currently unable to get UK prices for Cork insulation – anyone able to advise?

Lies, damn lies & statistics…
Don’t agree? Know better? Got a real world example to share? Are you a manufacturer or supplier with something to say?

    We’re just looking at flooring options and were thinking about using cork. I really like the look of the dyed cork tiles. We’re also looking at natural rubber.

    Good luck with drinking enough to line your walls with bottle corks!

    just an extra comment
    sheets or boards are agglomerated cork, not expanded cork.

    It means density is higher; average of 175Kg per cubic meter.

    a lot easier to cut without dust and the surface is more finer.
