Wooden exterior shutters rot and split apart

Forever Shutters TM - A Revolutionary Concept, Avoid the rot of our Competitors

What sets us apart is a unique manufacturing process involving placing reinforced stainless steel bar inside the back of our composite exterior shutters to give them a rigid shape. Since the material will not rot we back our exterior shutters with a LIFETIME guarantee. No more replacing wooden exterior shutters every 5-7 years. And unlike wood shutters, our exterior shutters are so strong the panels can never split apart. Made from a 1" thick version of the same material as our award winning and industry leading window boxes we are once again revolutionizing the industry with our Forever Shutter TM line.
