Hi, Can anyone see any problem with the following set up for a house wall? Outer layer (rain protection) compressed earth tiles treated with
water proofer. then an inner cavity to allow for moisture and water to drip down the back of the facade tiles without getting onto the next layer which is strawbale covered by a one way vapour barrier. I ask this question because someone today advised me to also have a board of some type in front of the strawbale but I would have thought that the strawbales would be rigid enough to stop wind. Could there be another reason for the cement board suggestion? many thanks
