Energy-Saving Insulating Glass for Building Facades

Insulating Glass (also known as Double-Glazed Glass or Insulated Glass Unit, IGU) is a classic high-performance energy-saving glass product that revolutionized building thermal management by solving the poor insulation flaw of single-pane glass—becoming a foundational material for energy-efficient architecture worldwide. Its core advantage lies in the hermetically sealed multi-pane structure: typically 2 or 3 panes of glass (float, tempered, laminated, or Low-E coated) are separated by a uniform gap (6–20mm) using aluminum or warm-edge spacers (filled with high-efficiency desiccant to absorb residual moisture), forming one or more airtight hollow cavities (filled with dry air or inert gases like argon/krypton for enhanced performance). This design delivers a service life of 10–20 years (varies by seal quality) while excelling in four key capabilities: Superior thermal insulation (U-value ranges from 1.5–2.8 W/(m²·K) for double-pane units and 0.8–1.5 W/(m²·K) for triple-pane—40–60% lowe…
