Sometimes an exterior door needs additional protection from the demanding elements of Mother Nature. Developed for exterior doors that are subject to harsher environments, Performance Series® is a selection of options that deliver maximum protection of your finely crafted Simpson door. We currently offer two Performance Series options, UltraBlock® and WaterBarrier® Technologies. The combination of these two technologies creates a door suited for the toughest exposures. And this protection is delivered without sacrificing the charm and craftsmanship you've come to expect from a Simpson door. After all, a beautiful door is only worth having if you can protect it.


WaterBarrier® Technology
(Patent Pending)

Available for a variety of entry, sash and French doors (see your Authorized Dealer for specific designs), WaterBarrier technology combines a Medium Density Overlay (MDO) with PVC glazing bead 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.

What is WaterBarrier® Technology?

  • One-piece of Medium Density Overlay (MDO) on outside for the very toughest exposures - commonly used on concrete forms and street signs
  • Minimizes the possibility of stile and rail separation
  • Eliminates checking on the face of the door
  • Excellent durability and resists moisture absorption
  • Overlay has thermoset acrylic latex primer topcoat, resulting in superior paint application
  • Can use water or alkyd-based paints on finish
  • PVC glazing bead provides moisture resistance
  • Choose any species to match interior architecture
  • Available for dozens of door designs
  • Five year limited warranty, no overhang required

UltraBlock® Technology (Available in all 1- 3/4" doors)

A long time favorite of Simpson's most discriminating customers, UltraBlock technology combines a composite block in the bottom of the stiles, where water infiltration typically occurs. Our exclusive Weather Seal™ process provides additional protection against moisture penetrating the bottom rail. It's our answer to the galoshes you splashed around in as a kid.
