It’s In The Details
Gentek designs, builds and delivers a full selection of windows specifically for new construction projects. Built weather-tough to meet challenging climates in any region, our windows are energy-efficient,1 beautiful, durable and virtually maintenance-free. Increased structural integrity and strength, along with superior PG/DP ratings and weathertight insulating components, combine for superior performance.
Gentek windows are tested to the rigorous requirements of the American Society for Testing and Materials (ASTM) test standards and criteria, as well as certifications from the Insulating Glass Certification Council (IGCC) and the National Fenestration Rating Council (NFRC). Using independent testing and certification agencies as well as our own state-of-the-art laboratories, Gentek windows are tested and proven to meet rigorous performance standards.
Energy efficiency is further increased with insulated glass packages featuring Low-E (low- emissivity) glass and a warm-edge spacer system. The spacer’s one-piece U-channel design provides a powerful thermal barrier that reduces conducted heat loss through the glass unit. Optional insulating argon gas2 also increases energy savings year-round – an added value for today’s builders and buyers.

J-Channel Quick Fix Repair Kit

Metal-Reinforced Mulling System

Increased structural integrity across optional mulled window units is assured with a metal channel securing one window unit frame to another. The metal band provides increased protection and rigidity for shipping and additional strength at the mull intersections for easier installation. This system is further enhanced with a drip cap at the top of the system that directs water away from the mullion.
Casement Opening Options

The standard casement opening design offers convenient cleaning of the sash from inside the home.

The egress hardware option provides a greater window opening area for compliance with building safety standards.
