WATERBARRIER ®
TECHNOLOGY
WaterBarrier® technology helps preserve the beauty of your
Simpson doors even in tough exposures subject to harsh
weather. Available for virtually any Simpson exterior door, this
innovation affords you superior water protection.
WaterBarrier combines a medium density overlay (MDO)
over the exterior surface of the door with water-resistant
glazing beads and bars for an exterior that’s not only resistant
to moisture, but provides a beautiful surface for paint. And
when combined with any wood species on the inside, you
can match your interior woodwork and keep the warmth and
natural beauty that wood provides.
