Pemko 252X3AFG Thermal Barrier Saddle Threshold - 5-1/8" Width x 1/2" Height
The Pemko 252X3AFG is a high-performance Commercial Thermal Barrier Threshold designed to eliminate the "thermal bridge" between exterior and interior environments. Measuring 5-1/8 inches wide and 1/2 inch tall, this threshold features a rigid vinyl center key that physically separates the aluminum extrusions. This "thermal break" technology effectively stops the transfer of heat and cold, preventing condensation and frost from forming on the interior side of the door.
High-Performance Features
- Advanced Thermal Break: The rigid vinyl strip provides a critical separation that significantly reduces energy loss and maintains interior comfort in extreme climates.
- ADA & Barrier-Free Entry: Fully compliant with ADAAG-1998, ICC/ANSI A117.1, and California Building Code Title 24. The 1/2" profile ensures a smooth, accessible transition for all users.
- Fire-Rated Safety: Rigorously tested under UBC 7-2 Positive Pressure and Category J certified, supporting up to 3-hour ratings on steel doors and 90-minute ratings on wood doors.
- Architectural Quality: BHMA Certified (ANSI A156.21) to guarantee industry-leading durability and material performance in high-traffic settings.
- Resilient Construction: Crafted from mill finish aluminum for long-term durability and resistance to heavy foot traffic.
