The extruded all aluminum frames and impact-resistant glass are engineered to withstand high winds and flying debris generated by severe storms and hurricanes. With the ability to achieve oversized, one-of-a-kind designs, even the most ambitious visions for coastal homes are possible. Designed and manufactured in Florida, Coastline products are available in select Southeast coastal regions. Unsurpassed Protection, Limitless Possibilities Advanced Coastal Performance Engineered to stand up to the high winds and flying debris generated by a tropical storm or hurricane, Coastline products meet the stringent Miami-Dade County and State of Florida code requirements. Coastline products provide peace of mind knowing your home is protected without having to take special measures each time there is a threat of severe weather. Premium Aesthetics Coastline products are made with the highest levels of workmanship at a new, state-of-the-art manufacturing facility in South Florida. The handcrafted details and superb fit and finish permeate these premium windows and doors with a beautiful aesthetic that will bring a sense of quality to any room and provide a clean, shutter-free, well-maintained aesthetic to your home. And our industrial-grade finishes withstand corrosion caused by humid conditions and salty air, and resist fading even after many years of direct sun exposure. Design Possibilities Coastline is the right choice for the most exacting architects, builders, and homeowners. Leverage scenic ocean views by creating an opening 50 feet wide with a bi-fold door, or create an architectural statement piece with a glass pivot door 12 feet high. Through the use of specialty glass and applied muntins of various widths and profiles, Coastline windows and doors are highly customizable and allow you to create one-of-a-kind solutions for even the boldest design aspirations. Coastline Windows Awning Awning window sashes are hinged at the top of the frame and swing out at the bottom. They are ideal for bringing in a breeze even in damp weather. COASTLINE AWNING Casement Provide vast, unobstructed expanses of glass while providing a clean feel and narrow sightlines. Perfect for hard to reach areas like over a sink or counter. COASTLINE CASEMENT Glider Also known as a horizontal roller window, a glider features an operating sash equipped with durable brass tandem rollers for easy operation. COASTLINE GLIDER Single Hung A traditional design that instills a sense of warmth, the Single Hung window features a stationary top window and a well-balanced bottom sash. COASTLINE SINGLE HUNG Picture Specialty Shapes These windows are available in hundreds of geometric shapes providing design freedom to create unique architectural statements. COASTLINE SPECIALTY SHAPES Picture The glass is glazed directly into the frame, eliminating the need for a sash, which results in narrow sightlines, more light, and larger unobstructed views.
