The Ultimate Energy-Efficient Window

What makes the casement window so energy-efficient? There are two features that come into play—its superior ventilation, and its ability to create an airtight pressure seal. No window ventilates quite like a casement does. It’s not just that it can open more widely than any other window on the market (though that helps); it’s that its shape when opened at an angle acts like a sail, guiding breezes right into your home, even when the wind’s blowing at an awkward angle. And unlike hung or slider windows, which simply slide shut, when you shut a casement window, its sash seals into the frame, restricting airflow, keeping your home’s temperature regulated and your heating and cooling bills low.

As the perfect complement to both your window and your home, our casement windows are available in Omni Series PVC, Optima Series PVC-aluminum hybrid, and Renaissance Series—which unites a PVC or aluminum outer frame to a wooden inner frame via a PVC core—frames, and are made with our best low-E, energy-efficient glass. Casement windows are a perfect choice for any home!
