FAQS
Are Specialty Windows Durable?
Yes. Pella specialty windows are built with the same high-quality materials and craftsmanship as the rest of our product lines. Whether you choose fiberglass, vinyl, or wood, each frame is designed to resist warping, rotting, and corrosion while maintaining its shape over time. Even unique designs like arch windows, triangle windows, or trapezoid windows are engineered for long-lasting performance and reliable strength.
How Much Do Specialty Windows Cost?
Specialty window cost varies based on the shape, size, material, and customization you select. Simple half circle windows or arch windows are typically more affordable than intricate custom shaped windows or large, dramatic designs. Wood and fiberglass options offer premium detailing and performance, while vinyl provides lasting value at a lower price point. Your local Pella Mid-Atlantic expert can provide an exact quote for your specific design and material preferences.
Are Specialty Windows Energy Efficient?
Yes. Pella’s specialty windows are designed with the same advanced glass technology and insulating materials as their standard window lines. You can choose from Low-E, dual-pane, or triple-pane glass options to help keep your home comfortable year-round. Even with distinctive shapes, like octagon windows, semi circle windows, or springline windows, you can expect exceptional energy efficiency and long-term performance.
What Customization Options Are Available for Specialty Windows?
With custom shaped windows, the design possibilities are nearly endless. Pella Mid-Atlantic offers a wide variety of shapes and styles—including circle, triangle, trapezoid, and arch windows—as well as your choice of interior and exterior finishes, grilles, and hardware. You can also combine specialty shapes with other window styles to create a dramatic architectural statement or highlight unique features in your home.
What Are the Maintenance Needs for Specialty Windows?
Specialty windows are designed for low maintenance and long-lasting performance. Vinyl and fiberglass options require minimal upkeep beyond occasional cleaning, while wood-clad designs feature protective aluminum exteriors for durability and weather resistance. Because most custom shaped windows are fixed (non-operable), they have fewer moving parts, reducing maintenance needs and ensuring long-term reliability.
What Materials Can You Get Specialty Windows In?
Pella Mid-Atlantic offers specialty shape windows in fiberglass (Impervia®), vinyl (250 Series), wood (Lifestyle Series), and wood with aluminum cladding (Reserve™). Each material provides unique benefits and delivers beauty and performance that last.
