Product Details
Elegant Design Meets Peak Performance
At Heritage Home Exteriors, we specialize in high-impact home upgrades, and nothing changes a room quite like the Endure™ Bay and Bow series. As an authorized ProVia dealer, we offer these windows to homeowners who want to “open up” their floor plan without changing their foundation.
Bay windows typically feature three panels—a large center fixed window flanked by two operable sashes (Double Hung or Casement)—set at sharp angles. Bow windows consist of 3 to 6 panels of equal size, arranged in a gentle, sweeping curve. Both styles provide an expansive view of the outdoors and a beautiful new interior ledge for your home.
Why Choose ProVia Endure Bay & Bow Windows?
1. Peak Energy Efficiency Because Bay and Bow windows project outward, they are more exposed to the elements. ProVia solves this with industry-leading technology. Every Endure unit is engineered with INNERGY® thermal reinforcements and high-performance ComforTech™ glass packages to ensure your new alcove stays as comfortable as the rest of your home.
2. Built for Structural Integrity These windows are heavy, which is why ProVia uses a specialized cable support system to ensure your window remains level and secure for decades. The frames are made from SunShield® vinyl, which is specifically designed to resist the fading and pitting that can occur with high sun exposure.
3. Furniture-Grade Interior Finishes The interior of your Bay or Bow window is just as important as the exterior. These windows come with high-quality, insulated head and seat boards available in various woodgrain finishes. This provides a warm, furniture-grade look that is perfect for a reading nook or display area.
