Window Systems

EXTECH's top hinged window systems feature 16mm or 25mm cellular polycarbonate glazing or insulated glass up to 1" thick. What sets them apart? The unique hinge mechanism allows the windows to stay open during normal rainfall, and prevents disengagement.  Massive ventilation is possible with these windows, which can be installed on continuous, unbroken runs. Perfect for retrofit applications or new construction, these windows can  be operated either manually or electronically.

Our systems are also fully fabricated, even further speeding up the installation process.

EXTECH's top hinged window systems are superior due to their advanced aluminum framing systems engineered for long term performance.  They have been tested to perform in a wide variety of environments for durability and longevity.
