Our old wall was made up of 2x4, then a horizontal 3/4 inch t and G siding, a 3/4 shiplap vertical siding, followed by a Styrofoam :insulation" and them Vinyl siding. In order to keep the same thickness for the new Vertical Metal siding we would put on we needed to double sheet 3/4 inch plywood to keep the outer surface even.
The bottom sheet is pressure treated 3/4 inch plywood and the top and inner layer is 3/4 inch sheeting grade.
By 6:00 PM we were done, all closed in and we are ready to resume work on the bathroom, Wet room and exterior wall as time permits in Sept and October.
Inside view finished.
