Insulated glass units (IGUs) comprise two or more glass lites separated by aluminum or warm-edge spacers and hermetically sealed, with the cavity filled with dry air or argon — forming the core component for energy-efficient windows and doors. Our standard double-glazing configuration with warm-edge technology achieves whole-window U-values as low as 1.0 W/(m²·K), and when combined with Low-E coatings and triple-glazing, winter heat loss and summer cooling loads are further reduced, helping projects easily meet local green building ratings.

Aluminum spacers can be bent into various special shapes, supporting integrated solutions such as internal magnetic blinds, decorative grids, and breathing curtain walls. Our production line uses automatic butyl coating, dual-component sealing, and argon gas-filling equipment, with initial argon fill rates stably exceeding 90% and seal durability validated at over 25 years through accelerated aging tests. Compliant with EN 1279 and GB/T 11944, it is ideal for passive-house windows in cold regions and large public building facades in hot climates — a high-value choice for bulk procurement in overseas energy-saving construction projects.
