Product Spec Sheet

WinDoor 4000 Series’ single hung window contains a lower sash that operates vertically while an aluminum frame holds the glass in a fixed position above.  While many consider the single hung window to be common for residential and commercial structures, the WinDoor 4000 is the perfect high impact product that offers great Energy Star ratings.  Heavy duty materials are used with robust spiral balancers, various glass options, and optional meeting rail reinforcement…all backed by the WinDoor name.
