Metal over exterior rigid insulation?
Hi all, I am an architect working with a private client on a farm structure in a cold-weather climate (many feet of snow accumulation during the winter months). I am trying to determine how we can utilize rigid insulation on the exterior of the foundation wall and finish it in a way that will protect the insulation, will stand up to nearby heavy-duty farm work, will not require ongoing maintenance as a result of freeze/thaw cycles, and will look attractive at any distance. I would also prefer a finish material than I can run below grade so as to eliminate the visual discontinuity that comes with ending a parge coat or other cementitious applied finish several inches above grade.
I have seen builders on this site recommend using a metal product, such as aluminum coil stock, as both a protective material and finish for this detail at the top of the foundation wall. However, I am having a difficult time selling my team on this idea and am also having a tough time finding images of metal-over-rigid online. I am hoping to crowdsource as many photos of this finish as possible. I am fairly certain it is a viable option for us, but I think our team is struggling with visualizing how it will work with our material palette (standing seam metal roof, dark blue Hardie siding). This is a fairly deluxe project, so photos of materials that may not work on a more conventional project (even something terne-coated, stainless, or copper) are also very helpful. The key is that the material should be resilient and attractive, not necessarily the most budget-friendly option. If you have other suggestions for a material that might work at this location in place of a metal finish, please let me know, keeping in mind our aesthetic requirements. Thanks very much for your help.
