Performance Series®

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 heavy-duty door components 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.
UltraBlock® (Available in all 1- 3/4" doors)
Long a 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.
What is UltraBlock Technology?
- Maximum protection against extreme weather conditions
- Composite block material finger-jointed into the bottom of the stiles eliminates water infiltration
- Minimizes stile and rail separation
- Eliminates bottom rail and lower stile rot
- Reduces buckling and swelling of bottom rail and lower stile components
- Improves warp resistance
- Beautiful genuine wood
- Five year limited warranty
All Simpson 1-3/4" doors are available with UltraBlock technology. This icon indicates this availability - look for it below the doors in our online catalog.
WaterBarrier™ (Patent Pending)
Available on select French doors, 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 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 in select French doors
- Five year limited warranty
