    Matt, please come back to this build to show us how it looks after it's been weathered for several months and over a year.

    Plus it doubles as a giant post it board!

    Had (1cm thick) cork panels instaled as interior insulation in one bedroom just to try it out. After installing them, the temperature diference with the other rooms was of about 4-5 degrees celsius, the mold/ damp problems completely gone and also a slightly better sound insulation I would say . I painted right on top of it, zero problems and it s been 5 years.Since then , I learned that you could install 10-15 cm panels on the outside of the house and they are weather proof, no need to install any cover or even paint it unless you want too, it s also a natural vapor barier , one of the best sound proofing material and bugs repelent. I ve seen houses isolated with cork with barely any usage of heaters or air conditioning. I live by the sea on the Spanish Mediterranean coast, it s warm here and this stuff ( cork) literally groes on trees over here and the factories that produce the panels are near by. We no longer use things like rockwool bcos it was proven to be toxic, the cork is more expensive but better all around on the long term. If you want to build a new house use "autoclaved aerated concrete " blocks with metalic structure ( for seismic resistance) and cork panels insulation on the outside. And of course a decent set of windows and doors. You ll never be cold again or suffer from the heat
  • A place close by was built in 1870 with 12cm of cork insulation behind the blue stone building construction. It still looks new to this day, I thought it was just something that was done long ago, but that building is so quiet inside and thermally stable it's surprising.
  • Matt, I did a report for a company that supplied tree bark siding for the outside of houses. Once it was baked, it was not subject to insects. Once installed, it had a unique and very decorative look. It was also insulating and lasted a long time.

    Cork from Portugal!! we are one of the world´s biggest producer of cork. used in construction here too! Good job really beautiful house!
  • @J_Urban_
    Can't wait to pin a message to the side of that house! 😂 In all seriousness though, it's pretty cool to see cork being used like this again.

    My house from the 60's is insulated with pretty thick cork. Works excellently, is sound dampening and is fire proof.
  • Fascinating material. I'd be nervous here in the wet northwest--just in terms of fungal rot--without a substantial rain screen and flawless lapping details.

    Love this channel keep showing us the alternative building trends
  • @jesinbeverly
    A lot of old cold storage facilities were insulated with cork.

    They used to sell thin rolls of cork as a decorative wall covering back in 1978 when I bought my first house in Michigan. I used it on the walls of a small bedroom with an accent wall of cork & mirror tiles. Beautiful! 12"×12" Cork/mirror tiles were sold in a box of 6 tiles.
  • Fantastic channel, a great place to learn. I really enjoy the way you approach different building materials and architecture styles. Keep up the great work!

    There’s a very cool house in England that uses cork blocks as structure, insulation and finish. The main issue I see with cork as a building material in the US is that it isn’t really grown here. Most production happens in the Mediterranean.
  • I've used cork as underlayment and it definitely makes good insulation. I have also installed cork flooring on several projects. However, the one takeaway that I experienced in all cases is that it is easily damaged. And while it's random pattern helps to hide defects as time passes and large chunks break off it looks terrible. At $4 to $6 a SF cork flooring was a costly mistake for us.

    I have!!! When I moved from Dallas back to Houston in the mid 1980's, as a member of the Box-4 fire buffs, I was naturally listening to the radio, hearing about the fire in the downtown all concrete building (4 foot think concrete walls/roof, etc), built in 1928 cold storage warehouse. The cold storage areas used cork as the insulation.
