Product of the Month: Sunrise® Casement Windows for Energy Efficiency

Energy efficiency becomes top-of-mind for homeowners when cold winds blow, and Sunrise® has technologically advanced windows that are designed to excel in this area. Our company is dedicated to producing the most energy-efficient windows on the market. We stand behind each and every window with a lifetime warranty and customer service that’s second-to-none.

Our casement windows are the most efficient operable window style we manufacture, and are second only to fixed (picture) windows when it comes to energy efficiency. This is because the sash of a casement window closes by pressing tightly against the frame, resulting in lower air leakage rates. When cold winds blow against the window, a casement seals even tighter!

More Efficiency Features

Many other factors contribute to our casement windows being energy-efficient. Sunrise window frames are made from premium virgin uPVC that helps keep your home better insulated. While other brands of windows use mechanically-fastened corners, Sunrise frames and sashes are fusion-welded, creating an impermeable barrier that eliminates water and air infiltration and adds strength where it is needed most. The frames are then filled with polyurethane insulating foam that ensures higher R-values than other PVC windows for truly effective insulation.

In addition, Sunrise casements feature two continuous seals of weatherstripping around the window’s perimeter to guard against cold air entering your home between the sashes and frame.

Multiple Panes for Better Insulation

Two panes of glass, with an air- or gas-filled space in the middle, insulate much better than a single pane of glass. Sunrise casement windows are manufactured with a 90% argon or krypton gas fill, or come air-filled for high-altitude areas. The glass panes are available in a variety of Low-E combinations that meet or exceed ENERGY STAR® requirements. Low-E glass protects the inside of a home from the sun’s heat and UV rays in the summer, and they prevent heat from escaping during winter.
