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.

The multi-pane glass panel design on door leaves offers an unobstructed view from indoors and a classical rhythm to the building facade. For those seeking historical authenticity, genuine muntin glass employs individual glass panes. Glass muntins come in various styles that mimic the appearance of single-pane windows within frames while maintaining the energy efficiency of single-pane glass.
Aluminum Spacer Bars—Featuring snap-on clips on the door frame exterior, these bars create a more secure connection with the frame, enhancing overall structural strength and ease of maintenance. A choice where aesthetics take precedence over function.
Double-Glazed Spacer Bars—Permanently installed grids between glass panels ensure low maintenance, a smooth appearance, and easy cleaning while maintaining decorative style. Available in multiple interior and exterior color options.
