The vinyl institute only provides installation instructions when the exterior shell assembly is 1" or less total. We are dealing with exterior assemblies with 1-2". CertainTeed has provided no help nor any testing data and they do not support the Foam Coalition Association recommendations. Any ideas? Someone else has to have this issue come up due to the new energy code.

The company has good solutions for adding continuous insulation to vinyl cladding, as well as metal, fiber-cement, and wood siding, to meet ASHRAE requirements for CI. They have specs and CAD details to help you get your requirements documented properly.

If you're installing over wood studs, you might consider Zip System which has continuous insulation, nailable sheathing and air barrier in one product.
