Superior Thermal Insulation

Three-panel technology.

Three-panel technology dramatically reduces thermal heat gain and loss, reducing the strain on HVAC systems and eliminating condensation issues. In addition, the third panel, as well as spectrally selective glass, provides an additional layer of protection against UV infiltration.

Sound Mitigation

One of the commercial industries primary concerns.

Our three-panel technology is so effective against exterior noise, that even our base line products offers an STC (Sound Transmission Class) rating superior to most premium products on the market today. We test and manufacture to a higher standard. The result is a far superior level of sound mitigation.

GEMI’s design and construction significantly limits moisture and climate exposure to these malleable components. The result is a superior product that will outlast and outperform.
