As a specification consultant to architects, I have recommended and specified the VSA line of siding products. I am confident in both their design and quality. In fact, I have used them in my own home.

VSA’s Third Wave product stands alone. It’s amazing how well it works to redirect water from penetrating the exterior envelope.

Third Wave Series products demostrate greatly improved water shedding performance over standard siding accessories.
