Salt Air Corrosion-Resistant Window Frames: What to Look For

Why Salt Air Is Hard On Window Frames

Salt does not need a storm to cause trouble. By the time the finish bubbles or the hardware feels gritty, corrosion has usually been working for a while.

A product that works well inland can age fast near the beach if the coating system, seals, and hardware were not built for coastal exposure. That is also why people shopping for impact windows often focus too much on the glass and not enough on the frame system.
