Design Pressure (DP) is a numerical value rating which defines the structural wind loading requirements for a building, and components or cladding of a building, described in pounds per square foot. Essentially Design Pressure represents the wind load the door system can withstand.
The following are general requirements for a Therma-Tru Continuous Door Unit with Venting Sidelitesto receive a DP rating:
- Door: 2-1/2” screws through the stile and into the top and bottom rails
- Door: Fiber-Classic or Smooth-Star
- Sidelites: No additional screws needed through sidelites
- Frame: Frame members connected to the rough opening can be wood or composite
- Mullpost: Must be a clear mullpost
During testing, the unit used a door with an entry lock and deadbolt. Due to the Fat Boy Mullpost (1” thicker) used with Venting Sidelite units, a unit was also tested using a multi-point locking system. Specific requirements exist based on the lock type used.
- Entry with Deadbolt: 8/0 doors need a 5-1/2″ Center on Center Bore
- Entry with Deadbolt: No additional screws needed on the strike mullpost
- Multi-Point Locking System: No additional screws needed on the strike mullpost
Below are the unit types that are possible as well as any specific requirements that are necessary.
