Did you know that Simpson Doors offers Performance Series doors that offer additional protection against the elements? Simpson’s Ultrablock and WaterBarrier technology are available on most exterior doors, and each upgraded door comes with a 5 year warranty.
WaterBarrier technology is made from one-piece of Medium Density Overlay (MDO) on the outside – a material commonly used on concrete forms and street signs. It resists moisture absorption and the overlay has a primer topcoat which results in better paint application. You can find if the technology is available on the door you want by visiting Simpson’s Find a Door.
Ultrablock technology already comes standard on many of Simpson’s door lines. This technology offers the best protection against extreme weather and improves warp resistance while still giving you a beautiful genuine wood door.
