Retractable pool enclosure up against an existing house
We are in a 5A climate zone, near Chicago. We wanted to add a retractable pool enclosure up against an existing house that would be used year round. http://www.libart.com/evolution-lean-to-structures
The existing house has a wall construction what has fiber cement siding, 1" rigid insulation with taped seams, Tyvek, 5/8" plywood, 2x6 framing with open cell insulation and drywall on the interior. See attached image. Keep in mind that this wall was build 9 or so years ago.
The interior of the house would be conditioned but so will the enclosed pool air although it would be a bit warmer and substantially more humid due to the pool. There probably will be a dehumidification system for the pool area but I think that would not completely solve this problem.
Our concern is with having potentially warm and humid air up against the existing house year round and how that affects the existing walls. We are planning on removing the existing siding and replacing it with impregnated fiber cement (significantly different than typical cement fiberboard) to help with durability. http://www.fibercementproducts.com/blog/?page_id=400 At that point the rigid insulation would be exposed and we could modify that surface as needed.
Additionally, we are building a new pool house area that would essentially have the same condition except we can build the wall from scratch correctly to address these conditions. Any feedback what would be ideal for the new walls would be great as well. We would rather get this wall built correctly than worry about cost.
Thanks in advance
