We are in the the middle of installing Marvin Evergreen Clad Windows with Clad Brick Mold Casing and Aluminum Nailing Flanges on a residential project. The building envelope is being waterproofed utilizing Prosoco Fast Flash products. The orange that you see on the sheeting is CAT5. The Red is Fast Flash. You do not see the Joint and Seam that was used to seal all the seams and joints prior to application of Fast Flash or Cat5. The windows and doors will use Marvin’s Aluminum Clad Nailing Flanges that will feature integrated corners.
