Increasing the thermal performance of a window or complete curtain wall system, insulated glass units (IGUs) reduce heat gain in warmer seasons while retaining more during colder periods. The following offering of products and customizable solutions improve on the standard to meet today’s increasingly strict requirements.

By securing a uniquely engineered film between two panes of glass, the Heat Mirror IG insulates like a solid wall. Eastman’s patented Heat Mirror technology can have an R-value of up to 20, making it suitable for use across a wide range of projects.

Comprising three panes of thermal insulation glass, the Iplus 3C easily outperforms older, uncoated alternatives and Ug-values down to 0.5 W/(m²K), which helps minimize heat loss. This low-E glass product hits the mark both in terms of performance and aesthetics.

In line with the latest trends, GGI’s Insulated Glass comes in double and triple glazing variants. A dual-sealed version—ideal for commercial use—features Super Spacer T-Spacer warm edge technology as well as air and argon gas-filled options to ensure greater indoor comfort.

These durable Cardinal IGUs meet the most exacting industry demands by incorporating two seals and a thin stainless steel desiccant gauge spacer. Filled with argon gas, there’s absolutely no way for heat to escape. Additionally, the product greatly reduces unsightly condensation beading.

Fitted out in 250T narrow, 350T medium, and 500T wide stile variants, Kawneer’s Insulpour Thermal Entrances achieve an optimal thermal break. The robust door-and-frame system features a new three-pane composition and can accommodate a wide variety of hardware.
