Available for virtually any Simpson exterior door, WaterBarrier technology combines a Medium Density Overlay (MDO) with PVC glazing beads and bars to create an exterior that stops water in its tracks. Select your choice of wood species and you've got the best of both worlds: water protection on the outside and the unmatched beauty of a real wood door on the inside. It's a perfect alternative to an expensive cladded door, and exactly the type of innovation you'd expect from Simpson.
