Rain screen is composted of a concrete panel with 2" of rigid insulation with a metal panel exterior face. The look is meant to give a sleaker and more modern look which contrasts the brutal nature of the bac.

Joe, Check your text, your floor slab in the foundation detail looks 4" but says 12".
Also, in your curtain wall section, you can place rigid insulation behind you spandrel panel to keep cold/hot transfer.
Hi Joe,
What system is that, sitting on top of your I-beam?
Joe, it would be great if you could show foundation, grade condition, typical window and roof condition for every wall system you are using. Right now your details are a bit disconnected.
Each detail by itself seems to make a certain amount of sense, but they don’t add up to a consistent picture of the building.
The indicated dimensions on the foundation detail are a bit random (8” foundation, 12” slab?). I like the water proofing and the foundation drain. Wouldn’t you want to connect it to a water table recharge element, rather than the storm system?
Do you have a basement in your building? If so, is there a plan?
I would love to see the foundation wall meeting the ground and “light” ground floor. What sill condition will you have? How do you transition the perimeter insulation into the exterior wall?
The standard curtain wall detail (where in the building is it used?) is a bit thin: I would like to see a serious effort insulating that wall system, and maybe showing some shading devices. Are there operable parts in your curtain wall?
On the parapet detail I have to ask you why you would want to add precast panels for back-up of a metal wall system, especially knowing that a fair amount of your upper two floors are hung off considerable cantilevers?
I think you would do just fine with light gage stud back-up, sheathing, air barrier 2” to 3” rigid insulation, air space and metal panel.
How will you detail this skin system to make it appear heavy?
werner/paul/felix,
-i think on the structural slab detail i was thinking 12" but drew it at 4" for some reason.
-thanks for the suggestion on the rigid insulation.
-the slab is composed of a 1 1/2' metal deck with concrete poured on top.
-i am still debating on how to resolve the issue at the floor condition/sill with the curtain wall meeting the slab, and how i can make that appear 'light.' i will work on the details and the elevations today and tomorrow and try and post all of that tomorrow evening.
werner,
one more thing, i did a little research on the water recharge comment, it looks like i can try and use that design strategy, but does effect the site and erosion with the steep slope?
Joe, anymore progress?
