H3 Double Hung
At the core of our advanced H3® is Fusion Technology™, the perfect integration of extruded aluminum, vinyl and wood. Its patent pending design and construction give it an industry-leading seal against the elements. It's also extremely durable and easy to install.
- Wood interior for warmth and beauty. Not just a veneer like some windows.
- Extra-strong 0.078” vinyl base frame for superior rigidity, total protection against rot, and enhanced resistance to air or water leaks. No vinyl components are visible when window is closed.
- Extra heavy duty 0.055” extruded aluminum cladding. At least twice as thick as competitors’ roll-form cladding.
- Integral rigid nailing fin for greater structural integrity, improved water barrier and easy installation. Virtually eliminates racking problems.

- Choose from four innovative brickmould frames. Each uniquely integrates trim for designer styling, while still taking advantage of a nailing fin installation.
- Protected by our exclusive CoreGuard Plus™, the industry’s best wood protection.
- Many design options available.
