Salt air vs aluminium: why coastal Jamaica chooses uPVC

What salt does to metal systems

Aluminium near the coast often shows white oxidation, stiff operators, and gaskets that shrink away from the frame. Steel stains walls with rust streaks that paint cannot hide for long.

Domus uPVC does not rust. Stainless hardware and UV-stable frames keep openings serviceable when maintained with simple wipe-downs.

Total cost over a decade

First invoice is only part of the story. Paint cycles, gasket replacements, and early frame failure add up. Warranty-backed Domus frames shift that cost curve toward longevity.
