The single slider window is our most practical and affordable window. It combines
sophisticated style with ENERGY STAR status for a versatile addition to any
home. When used with our Low-E glass insulated with krypton gas, it reaches an
energy rating of 38.
One sash of these horizontal sliding windows opens smoothly thanks to our Insta-Lok
shoe, while the other remains fixed. The inward opening of the sliding pane makes
cleaning a breeze.
