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 Simpson Door constructed with a Mortise and Tenon in a Therma-Tru Continuous Unit to receive a DP rating:
- Door: No screws required in door slab
- Door: Only approved Simpson door slabs to be used (See Below)
- Glazed (Glass) Doors can only be SDL Glazed
- All 8/0 doors require surface bolts on active and/or passive doors
- 6/8 Doors: Entry with Deadbolt 5-1/2” On Center Bore
- 8/0 Doors: Entry with Deadbolt 12″ On Center Bore
