Replied to My Question on Hemp Building:

I’m designing a Hempcrete home and have been looking into a Catalan Style Spanish Roof for a roof system that does not require lumber. Do you think a hempcrete product would replace the concrete the spanish masons use? I’ve started a series of articles on the planned build at: http://stlouisrenewableenergy.com/2014/02/05/hemp-home-catalan-vaulted-style-roof-waterproofing/

Mr. Greg Flavall Co-Founder / Technical Director Hemp-Technologies Answered:

“”having looked at your website and design I’m intrigued. Although we have not done this style of roof I do not see what lime could not do the same as cement in this application- if it were sealed correctly.  Typically we are using Hemp/Lime for walls which is covered with 15-20mm of lime plaster for weather protection on a vertical plane. We install hemp/lime under the roof where it is protected as insulation and in the floor (above grade only) where it can breathe.””

Why would you not consider a green roof cover in this style, much like the Adnams Brewery project in UK completed in 2008? Seems to me a better use of area.
