Specialty Shaped Windows

Available in hundreds of geometric shapes, specialty-shaped windows provide you the freedom to create unique design statements while protecting your home from hurricanes. 

  • Glass is glassed directly to the frame, eliminating the need for a sash
  • Available in widths up to 13' or heights up to 13'
  • Available in shapes including circle, half circle, oval, arch, triangle, trapezoid, hexagon, and octagon
  • Nine colors and wood grain finishes plus custom colors
  • Optional decorative glass and divided lites

Specialty Shaped Window Finishes

Our low-maintenance interior and exterior finishes resist fading, peeling, and chalking even under the most extreme coastal conditions. Finish options include five colored finishes and five wood grain finishes that will bring beauty and natural warmth to your home. 

Our Bronze, Black, Bronze, and Stone White Kynar finishes are AAMA 2605 certified. AAMA 2605 is the American Architectural Manufacturer's Association's high-performance exterior specification. Finishes meeting this certification exhibit outstanding resistance to humidity, color change, chalk, gloss loss, and chemicals. 

We also offer custom color options to create your unique, coastal window and door vision.

We were in need of window and door upgrades. SIW did an exceptional job at a reasonable price. Management and staff were outstanding. I highly recommend this company. Thank you for your excellent service!

Viviana C.

We had 24 windows, four sliders, and two doors all installed at the same time. Flawless, and as smooth as could be. The quality of the windows and doors is great. Cannot say enough positive things about the entire experience, from start to finish.
