Profiles and opening size
Aluminum systems often support slimmer sightlines, large openings, commercial applications, and extensive mulled configurations. Exact limits still depend on the tested system.
Thermal behavior
Vinyl frames and thermally improved aluminum can both support energy-efficient packages. Compare the documented whole-product U-factor and SHGC rather than material assumptions.
Finish and architecture
Aluminum may offer anodized and broader custom-finish options. Vinyl color ranges vary by system. Match exterior standards, interior appearance, coastal exposure, and maintenance expectations.
Choose by approved fit
Start with the required operation, size, pressure, frame depth, egress, glass, finish, mullions, and installation—not a universal material winner.
Turn the guide into a real opening schedule.
Keep every dimension, option, pressure, document, and delivery note connected to the same opening ID.

Which material lasts longer near salt air?
Service life depends on system quality, finish, hardware, exposure, cleaning, drainage, installation, and maintenance. Review coastal-use requirements for the exact product.
