4000
Aluminum Single Hung Window

The 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 NFRC ratings. Heavy-duty materials are used with robust spiral balancers, various glass options, and optional meeting-rail reinforcement … all backed by the WinDoor name.
