Simonton Specialty Shapes Windows offer a way to elevate your home with bold geometry and custom style. These fixed (non-operating) windows are available in circular, arched, and linear forms—designed to highlight architectural details and frame breathtaking views without distracting hardware. Whether used as a standalone feature or combined with operable windows like double hung or casement units, specialty-shaped windows bring visual interest and a custom aesthetic that complements both traditional and modern designs.

Because specialty shapes are fixed, they deliver excellent performance with fewer points of potential air or water infiltration. Simonton builds these windows with fusion-welded, one-piece frame and sash assemblies for structural strength and durability.  In glass design, they use energy-efficient double-strength insulating glass, optional Low-E coatings, argon gas fills, and non-conductive spacers to strengthen thermal performance. The result is a window that combines artistry with lasting protection, sealing tight against elements while preserving clarity and elegance.

Certain specialty shape lines, such as DaylightMax Specialty Shapes, are engineered with ultra-narrow frames (e.g. 2-7/8″), increasing glazing area for more light and clearer sightlines.  This slim profile enhances contemporary aesthetics and ensures the window itself doesn’t dominate the architecture—light takes center stage.

Simonton builds its specialty shapes with high-quality vinyl, designed for durability and minimal upkeep. The weather-resistant material resists pitting, peeling, and corrosion—so your custom window retains its beauty over time.

Vinyl’s natural insulating properties help reduce thermal transfer, contributing to energy savings when combined with high-performance glass. And because specialty shapes are fixed, there’s no wear from moving parts, which further increases longevity and performance.
