Discover the Benefits of Prime Vinyl Casement and Awning Windows
If you’re looking for stylish, durable, and energy-efficient windows, Prime’s Series 720 vinyl casement and awning windows are a smart choice. These windows combine sleek, clean lines with high-performance features, making them a great fit for a wide range of architectural styles.
Casement and Awning Operation
Both the casement and awning windows operate with easy-to-use crank handles. Casement windows open outward from the side, while awning windows are hinged at the top and open at the bottom. This design offers excellent ventilation while keeping rain and outdoor elements at bay.
