The two primary glass configurations for Fort Lauderdale impact windows are a standard PVB laminated assembly and an upgraded SentryGlas Plus (SGP) laminated assembly. PVB interlayers satisfy HVHZ requirements for most residential openings and represent the most commonly specified option. SGP interlayers are stiffer and more tear-resistant, which makes them the stronger choice for larger openings, ground-floor windows with higher debris exposure, or homeowners who want the maximum available protection. Haven specifies the interlayer type based on the engineering requirements of each opening rather than applying a single default across the project.
Frame selection in Fort Lauderdale almost always comes down to aluminum versus vinyl. Aluminum dominates along the coast because it handles salt exposure without degradation and achieves the design pressure ratings that HVHZ code demands in a relatively slim profile. Vinyl frames with thermal breaks offer better insulation values and can reduce cooling costs, but they require wider profiles at higher design pressures, which can reduce the visible glass area in certain openings. Haven presents both options with the engineering data for each window so the homeowner makes the decision with complete information.
