Fixed windows typically achieve higher design pressures than operable windows due to having no moving parts. Standard fixed windows can achieve +/-75 PSF, architectural systems reach +/-90 PSF, and structural glazing can exceed +/-100 PSF with appropriate engineering.
Maximum sizes depend on design pressure requirements and frame system. Standard fixed windows can reach 60 SF or larger per lite. Architectural systems can exceed 100 SF, and structural glazing can achieve 150+ SF with appropriate glass thickness and support.
Yes. All fixed windows in Miami-Dade HVHZ must have a valid Notice of Acceptance (NOA). The NOA must cover the specific size, glass makeup, and design pressure required for your application. Structural glazing may require project-specific engineering approval.
Glass thickness depends on unit size and required design pressure. Typical impact fixed windows use 7/16" to 9/16" laminated glass. Large architectural units may require 11/16" or thicker multi-laminate constructions to achieve required pressures.
