What is the recommendation for the weather-resistant barrier / waterproofing?

Each application is entirely different. The substructure must be built to be weather proof and we are decorative cladding that is not designed to keep moisture out. It is up to the architect, engineer, installer, and local code official to ensure the structure is weather-tight and meets code.

Does the installation require 2x4 pressure treated furring strips?

Yes, our code compliance research report requires a minimum 2x4 PT furring strips. Our experience with smaller or thinner furring strips is they split and lose their holding power.
