If you need windows that are energy-efficient by design, allow both ventilation and daylighting, and capture a beautiful view, choose casement windows. Not all casement windows are built the same way, though, so before you make your choice, consider the following factors.
Frame and Sash Material – Casement windows are energy-efficient because of their hinged design. The sashes press against the frames when closed, creating an airtight seal that prevents heat leaks. The frame and sash material, therefore, need certain characteristics to achieve this seal. They should be strong enough to support the weight of the glass and have insulation, and they also need to be stable enough to withstand temperature extremes without warping. Renewal by Andersen® replacement windows have Fibrex® frames and sashes. Fibrex is a composite that has all of these features and more.
Dual-Pane Window Glass – Glass naturally conducts heat. It also occupies the largest area in any window. When choosing casement windows, pick the type that’s equipped with dual-pane glass, just like all Renewal by Andersen window replacement units. Our exclusive High-Performance™ Low-E4® glass packages eliminate contact between interior and exterior surfaces, which minimizes conduction and helps save on your indoor cooling and heating costs.
Low-E Coatings – Sunlight, particularly invisible infrared rays, is another source of heat. Ultraviolet (UV) rays cause fabrics and furniture to fade. Both being forms of light, they can pass through dual-pane glass with ease. Window glass with emissivity coatings (Low-E low) blocks unwanted UV and infrared rays and, unlike window tints, lets visible light through just like clear glass. Low-E coatings are yet another feature of our High-Performance Low-E4 glass packages.
Hardware – Casement windows have a unique set of hardware requirements on which you should never skimp. The hinges, in particular, have to be strong enough to carry the weight of the casement window sash while the locks have to be durable enough to ensure security over time. When you choose Renewal by Andersen for your window replacement project, you can rest assured all parts – frames, glass, hardware – will be top-notch.
