[GSBN] Straw Bale in Marine Environments

[Rene Dalmeijer]

Hi David,

I will second Martins suggestion of using a Larch rain screen. I have seen and stayed in his SB house in Brittany it is in very exposed situation and the rain screen is very effective. One thing to watch out for is watertight detailing around openings, water can travel uphill given sufficient wind pressure. I have used Larch cladding on most of my projects and until sofa only experienced problems around openings due to incorrect detailing.

We've discussed using straw bale panels for the exterior walls (and possibly party walls) of these multi-unit buildings.  One of the structures will be located only meters away from the bluff above the ocean.  Yes, beautiful, but sometimes very foggy, and heavy rains with high winds at times, too.

Our structures will have 3' to 4' (1 meter +)overhangs to the west, north and east, and 6' to 8' (2 meter +) toward the south (and no bales on the south walls).  All sites receive a good amount of sun (no significant trees or hills).
