Frequently Asked Questions

Expert answers for architects, engineers, and contractors.

What wind speed must sliding doors withstand in Palm Beach County?
+
Sliding doors in Palm Beach County HVHZ must withstand 180+ mph wind speeds with impact resistance. Standard areas require 150-170 mph ratings. Multi-panel systems require additional structural reinforcement at each track junction. The design wind speed is determined by ASCE 7-22 maps and building Risk Category.
What is the maximum panel width for impact sliding doors?
+
Maximum panel width depends on glass thickness and frame system. Typically 48-60 inches for residential and up to 72 inches for commercial with reinforced framing. Larger panels require thicker laminated glass assemblies. For HVHZ zones, panel width is often limited by pressure rating rather than structural capacity alone.
Do pocket sliding doors have different wind load requirements?
+
Yes, pocket sliding doors require additional header and jamb reinforcement since panels retract into wall cavities. The pocket framing must resist lateral loads and the track system needs enhanced anchorage to meet HVHZ standards. Engineering calculations must account for the reduced wall section at pocket locations.
How do multi-slide systems affect wind load calculations?
+
Multi-slide systems (3+ panels) require cumulative load calculations at meeting stiles and header tracks. Each additional panel adds connection points that must transfer loads to the structure. Systems over 16 feet typically need intermediate support posts. The tributary area for each panel affects pressure coefficients.
What glass specifications are required for HVHZ sliding doors?
+
HVHZ sliding doors require laminated glass with minimum 0.090" PVB interlayer. Typical configurations are 1/4" + 0.090" PVB + 1/4" for smaller panels, scaling up to 3/8" + 0.090" PVB + 3/8" for larger openings. Impact-rated insulated glass units add another laminated lite for thermal performance. All glass must pass TAS 201 missile impact testing.
