Glass Craftsmanship
Multiple glass craftsmanship options are available to meet the unique requirements of each project. Additionally, insulated glass units come in clear, green, brown, or various tinted colors, and can incorporate built-in blinds.

Energy Efficiency & Environmental Protection
Our standard glass configuration features double-pane insulated glass with low-emissivity (Low-E) coating: both panes are coated with a low-emissivity layer and filled with xenon gas for thermal insulation. Low-E glass, also known as low-emissivity coated glass, features multiple layers of metal or chemical coatings on its surface that reflect infrared and ultraviolet radiation. While standard glass has an emissivity as high as 0.84, Low-E glass reduces emissivity to below 0.15. We offer various specifications to meet global climate and regulatory requirements. For details, please refer to our product catalog's glass section.

Specialty Glass Options
Our specialty glass portfolio encompasses materials for diverse requirements, including sound control (STC/OITC) glass, solutions for tropical desert climates, and high-altitude glass. Additionally, we provide laminated glass specifically engineered for hurricane-prone regions.
