Triple glazed IGU, various configurations (36mm, 40mm, 44mm, 52mm total unit)
High-performance triple-pane insulated glass units offering superior thermal insulation (U-value 0.5-0.9 W/m²K) and acoustic performance (STC 36-40+) for premium building applications
High-performance triple-pane insulated glass units offering superior thermal insulation (U-value 0.5-0.9 W/m²K) and acoustic performance (STC 36-40+) for premium building applications
Triple glazed IGUs consist of three glass panes separated by hermetically sealed spacers creating two insulating cavities filled with air or argon gas. Available in 36mm, 40mm, 44mm and 52mm overall thicknesses, these units incorporate low-E coatings and warm-edge spacers to achieve exceptional thermal performance. Primarily specified for high-performance residential and commercial projects in cooler climates or where superior acoustic isolation is required.
