All our Coastal door hardware components are manufactured with durable, corrosion resistant metals, and the finishes are formulated to stand up to high humidity, salt spray, and the intense UV rays from the sun.

Glass
Decorative Glass
Coastline windows and doors are built with impact resistant glass that is engineered to stand up to the punishing winds and flying debris generated by tropical storms and hurricanes. And you don’t have to sacrifice design flexibility for strength. There are a wide variety of decorative patterns available to meet the unique needs of each project including rain, glue-chip, and obscure. We offer several interlayer, laminated tinting options that will increase privacy, reduce solar heat gain, and meet the requirements of the Sea Turtle Conservation Codes. Coastline products can be fitted with insulated glass to help conserve energy. We can also provide specialty impact resistant glass solutions for specific project needs like sound management.
