Simpson® Performance Series® doors include components that provide additional protection to your door in harsh weather conditions. Performance Series doors utilize three moisture blocking features. First, they utilize UltraBlock® Technology which is a water-resistant composite block added to the bottom of both door stiles.
Additional glue is also added to the holes for the dowels pins.
Second, they feature the Weather Seal process. The sides of the rails are covered with glue.
Including glue where stiles and rails meet blocks water absorption and enhances the glue joints.
Finally, all Simpson Performance Doors stocked by Reeb come with a solid bottom rail. Solid lumber is very durable especially in this vulnerable area of the door. By incorporating all three of these into a door, the entire bottom of the door is protected against moisture penetration. Reeb stocks Performance Doors in Douglas Fir, Sapele Mahogany, Ponderosa Pine, and Red Oak; they come with a 5 year limited warranty in a partially protected doorway.
