Answers to frequently asked questions about bi-fold doors in Broward County.
Folding glass doors in Broward County HVHZ typically require design pressures of +/-55 PSF for residential and +/-65 to +/-75 PSF for commercial applications. Requirements increase with opening width and building height.
Impact-rated bi-fold systems are available with 2 to 8 panels, allowing openings up to 32 feet wide. Larger systems require higher design pressures and more robust hardware to meet HVHZ requirements.
Yes, properly rated folding doors can meet the same HVHZ requirements as sliding doors. The key is selecting systems with Miami-Dade NOA approval that meet TAS 201, 202, and 203 for large missile impact and cyclic pressure testing.
Critical hardware includes heavy-duty stainless steel hinges rated for the door weight, reinforced multi-point locking systems, structural track systems, and flush bolts at floor and head for each panel.
