YKK AP America Inc. has introduced the Model 50H wide stile door as its newest addition to the ProTek product line. The Model 50H adds a 5-inch-wide stile option to the ProTek door line-up to complement Model 35H, a 3 1/2-inch medium stile option. The door achieves exceptional impact resistance, while also exceeding the most stringent energy codes.
Designed to integrate with storefront and curtainwall-framing systems, the Model 50H door has been tested to meet the stringent standards of: Florida’s High Velocity Hurricane Zone (Miami-Dade and Broward Counties), Blast Mitigation Testing – ASTM F 1642 – Level 2, and Water Performance – ASTM E 331 –10.5 PSF. The new door was also tested in accordance with ASTM E 1886, ASTM E 1996, and it passed the Large Missile D test, to protect against large projectiles during high wind events. It can also incorporate lighter-duty glazing options that meet Small Missile A tests to protect against smaller projectiles such as roof gravel from adjacent buildings.
The door was tested with a variety of locking, hinging and threshold options such as:
- • Rixon Pivot Hinges
• Butt Hinges
• Continuous Hinges
• Single Locks
• Three-point Locks
• Five-point Locks (for pairs)
• Rim Panic Devices
• CVR Exit Devices
This wide variety of hardware, style and rail options provides architects with the flexibility that has only been previously associated with non-impact entrance systems.
The Model 50H door derives its strength from its all aluminum stile and rail construction and unique corner design, which features welded seams. It gets its energy efficiency from a unique glazing pocket design, which can accommodate up to 1-inch laminated insulating glass. The 2 3/8-inch-thick door panel can accommodate a variety of insulated or monolithic glazing options ranging in thickness between 1/4 and 1 inch. Both wet and dry glaze options are available up to 90 PSF.
The Model 50H door is available in single panel widths to 4 feet, double-door widths of 8 feet, and heights to 8 feet. It is available in multiple rail heights as well as with muntins between the glass.
