Integrity Ultrex Double Hung Window

Bring traditional beauty where it hasn't been traditional.

Integrity All Ultrex Double Hung windows have beautiful, virtually indestructible interiors and exteriors made of Ultrex, meaning almost no maintenance for a homeowner. The Ultrex finish resists scratching and fading and will never flake; elegant traditional double hung styling with 21st-century technology.

The All Ultrex Double Hung window offers clean, even and measured sight lines that provide significant depth where historically only a flat vinyl facade has been present. Add superior DP50 performance on a majority of sizes, factory applied installation accessories and unparalleled delivery and this window not only looks great it performs great. Mull with picture units, transoms, other Double Hungs or Polygon units to create a myriad of assemblies.
