This Andersen 100 Series Casement Window features durable, low-maintenance Fibrex composite material and energy-efficient Low-E glass. Low-E glass is an ideal choice for climates where both heating and cooling costs are a concern. The window cranks open easily for fresh air and the slim-profile hardware won't interfere with your blinds or shades. From inside your home, the locking mechanism can be found on the left-hand side of the window which means the window cranks open to the right. Sleek frame profiles maximize glass space and natural light while the grille pattern adds character. This model includes a dark bronze exterior and interior, dark bronze hardware, dark bronze insect screen and Low-E glass.
