The Fantom Operable Glass-in-Glass Window: A New Standard in Seamless, High-Performance Glazing

In modern architecture, the demand for seamless aesthetics, high energy performance, and long-term durability continues to drive innovation in façade and window design. At the intersection of technology and elegance lies the Fantom Operable Glass-in-Glass Window, powered by AESTECH Engineering and introduced to the US, Western Canada, and Central Canada by SkySheer. This groundbreaking solution redefines what’s possible in operable fenestration by eliminating visible aluminum frames and integrating fully within insulated glass units (IGUs), achieving a flush, frameless visual experience with exceptional performance.

Ideal for multistory residential developments, commercial office buildings, and bespoke custom-built homes, the SkySheer's Fantom Operable Glass-in-Glass Window offers a combination of functionality and minimalism previously unseen in the market. Designed to perform as in-swing or out-swing awnings, casements, or tilt-and-turn units, each Fantom window is engineered to blend invisibly into AESTECH’s frameless glass curtain wall systems, delivering true glass-to-glass transparency without the need for aluminum mullions or perimeter framing.

Performance Beyond Aesthetics: The Thermal and Structural Benefits

While the architectural appeal of the SkySheer's Fantom Operable Glass-in-Glass Window is immediately apparent, its performance advantages are equally impressive. Traditional aluminum-framed operable windows disrupt the thermal continuity of IGU façades, introducing thermal bridging and reducing energy efficiency. By contrast, the Fantom window’s frameless integration retains the full thermal insulation potential of double- and triple-glazed IGUs, significantly reducing heat loss and improving interior comfort across all seasons.

In addition to its thermal performance, SkySheer's Fantom Operable Glass-in-Glass Window addresses a critical yet often overlooked engineering challenge: material expansion under thermal load. Aluminum has a higher coefficient of thermal expansion (CTE) than glass, which can create stress concentrations at the interface between framing and glazing over time. This can lead to seal failures, air and water infiltration, or even glass breakage in extreme cases. By eliminating aluminum frames and mullions, the Fantom glass-in-glass design minimizes differential movement and internal stresses, enhancing the durability, long-term stability, and structural integrity of the entire window system.
