WaterBarrier^® Technology

WaterBarrier Technology = 5 Year Warranty with no Overhang Requirement

Available as an option for virtually any Simpson exterior door, WaterBarrier technology combines a Medium Density Overlay (MDO) with water-resistant 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.

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
• Exterior side of the door is to be painted. Interior side can be painted or stained.
• Can use water or alkyd-based paints on finish
• Choose any species to match interior architecture
• Available for virtually any Simpson door. To see if your door can accept WaterBarrier technology, visit Find a Door.
• Five year limited warranty, no overhang required

UltraBlock^® Technology

Available in all Exterior doors; 5 Year Warranty

A long time favorite of Simpson's most discriminating customers, UltraBlock technology adds a water-resistant composite block in the bottom of the door stiles, where water infiltration can occur in a tough exposure. 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.

UltraBlock technology is already included on most Simpson entry doors. And for doors that do not include it as a standard, it can be ordered as an option. Simply let your Authorized Dealer know you want UltraBlock in your door.

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
