Stucco over 4-inch rigid foam?
I am trying to figure out if I am crazy for wanting to Stucco over 4 inch rigid insulation…
I am building an earthship-inspired house in a county with no building codes. As you can see in the picture, the southern wall of the home is a row of glass windows that sit on top of a concrete “footer” that is on top of 3 rows of tires.
The glass will be a huge loss of heat and we want to insulate the tires on the out side of the home.We have an abundance of 4×8 sheets of 4″ insulation and want to use it to insulate the tires and concrete. Tires are 30″ tall and concrete is another 14″. Tires a packed with sand.
From the research I have done it seems like the problem I would run into is being able to fasten the insulation and lath well enough to the tires so that when the weight of the stucco is applied it doesn’t give. Are there other issues? Would 5″screws that go through the tires be sturdy enough? I am also wondering about how a weep Edge wood look on this design. Any advice or suggestions are greatly appreciated. Thank you in advance
