Dear Chita, I'll explain the idea when I read Chris email: 1- Project is in Extremadura - Spain. Cork forest exists there and is extremly important there. 2- I read he was thinking of mortar with cork granules in order to insulate the building as it would need to last a while longer than initially planned... 3- He also refers mineral wool so the suggestion to cork seemed natural to me. It is required less thickness despite similar lamda values, because cork has a higher inertia. 4- Cork is really not unobtanium, it really works great, it is tested for more than 50 years and does not loose its insulation properties during the time.
For your pivotal question about price you are right at some level. Cork is not a free product and is more expensive than EPS for instance. However it fullfils his requirements on his initial request: sustainable (or least recyclable) and durable. So, at the end, the material will be local! Sustainable! and not from outer space like the great unobtanium that makes wonders... Excuse me if by anyhow I misinterpreted the request. For an alternative in terms of building there are many "new" trends in alternative building: http://www.youtube.com/watch?v=93Y_ctwhNso Regards, Francisco On 19 April 2012 18:28, Chita Jing <[email protected]> wrote: > > > On Thu, Apr 19, 2012 at 7:12 AM, fsim <[email protected]> wrote: > >> Dear Chris, >> >> May I suggest you use Insulation Cork Board. >> Further information can be found on: >> http://www.bcork.amorim.com/en/constructive-solutions >> >> I don't want to single out this company because so very very VERY > many companies do it -- I just want to say that I usually don't read most > ads any more when they are coy about the cost of what they are selling. > It's the same reason I buy so much online: my time and money are precious. > I can't go through 123 pages of bragging to get to a Form that basically > collects ALL my data - so they can spam me with phone calls and emails. > Most companies who are (or want to be in) the alternative-construction > business really don't care about small users and their pricing reflects > this focus. > > I've been into alternative building for more than thirty years now (I > graduated from Shelter Institute in 1978) and I've seen that MOST of the > things being touted in the 70s did not work out as planned.
