Quality Edge's Vesta Siding: Tie it altogether with coordinating and interdesigned J-Channel, corner post, trim and more. It’s these details that create a crafted design that is as beautiful as it is durable. Siding accessories such as trim not only add the finishing touches to windows, doors and corners, they protect the exterior. And unlike wood or vinyl, Quality Edge accessories won’t absorb moisture, rot, fade or require maintenance.
