I am about to install a new Sliding Patio Door. I have (2) questions regarding the installation:
(1) It is my understanding that you can not flash directly over the new Pressure Treated Wood with Aluminum because of corrosion concerns from the Highly Alkaline formulation. How do I flash over the new formula pressure treated wood? ... and what type is the best sealant? ... silicone rubber or polyurethene construction adhesive?
The manufacturers of pressure treated wood recommend stainless steel fasteners in contact with their treated products. I assume that this would extend to flashings or any other metals in contact with such materials. Maybe you could cap the treated wood members with an untreated 1 x where in contact with the aluminum.
