Over the past two years, in Douyin’s construction‑fitout and high‑end property‑renovation segments, double‑silver LOW‑E insulated glass has emerged as a best‑selling energy‑saving material, effectively addressing key pain points of conventional insulated glass—poor thermal insulation, sweltering heat under summer sun exposure, excessive energy consumption, and glaring glare from exterior façades.
Over the past two years, in Douyin’s construction‑fitout and high‑end property‑renovation segments, double‑silver LOW‑E insulated glass has emerged as a best‑selling energy‑saving material, effectively addressing key pain points of conventional insulated glass—poor thermal insulation, sweltering heat under summer sun exposure, excessive energy consumption, and glaring glare from reflective façades.
Unlike single‑silver LOW‑E glass, double‑silver glass features a dual‑layer silver coating that doubles its thermal insulation performance, while delivering high‑definition light transmission, low reflectance, and superior energy efficiency. Its exterior boasts a sophisticated matte finish, making it ideal for modern minimalist curtain walls, upscale residential projects, and commercial office buildings—making it the preferred energy‑saving glass for today’s green and ultra‑low‑energy buildings.
Guangdong Haibo Special Glass Technology Co., Ltd. As the original manufacturer of Foshan Shuangyin LOW‑E glass, we specialize in custom deep processing of double‑silver LOW‑E glass. Our coatings are uniform and stable, with optical and thermal performance that meets national standards, making them ideally suited to South China’s hot, sun‑exposed, and humid climate. With long‑term use, they resist oxidation and delamination.
Our factory’s best-selling double-silver LOW‑E glass meets key national standards: it fully complies with GB/T 2680‑2021 and the JGJ/T 151 energy‑saving code. The standard 6+12A+6 insulated double‑silver configuration offers a visible light transmittance of 60%–70%, providing bright, well‑lit interiors without dimness.
The solar shading coefficient (SC) is 0.40–0.45, placing it in the medium-to-low shading, high-performance category and effectively blocking solar radiant heat. The U-value ranges from 1.4 to 1.6 W/(m²·K), significantly better than the 2.8 W/(m²·K) of standard insulated glass, resulting in an energy-saving improvement of over 40%.
Double-layer silver‑film vacuum magnetron sputtering technology ensures the coating is oxidation‑resistant and corrosion‑proof, with an outdoor weathering lifespan of ≥15 years. Its low‑reflectance design achieves an exterior reflectance of ≤15%, eliminating light pollution and complying with urban curtain‑wall building codes. The entire product line features homogeneous tempered glass substrates, with a spontaneous breakage rate of ≤0.01% and shatter‑producing blunt‑angled fragments, ensuring safety and regulatory compliance.
Guangdong Haibo Special Glass Technology Co., Ltd. offers custom fabrication of extra-large panels, irregular curved shapes, and non-standard thicknesses. As a factory‑direct manufacturer based in Foshan, we provide integrated coating, tempering, and insulating‑glass assembly—without any markups from intermediaries.
All double-silver LOW‑E glass comes with energy‑efficiency test reports and 3C certification; fully compliant and ready for inspection, it meets the requirements of green building assessments. Offering long‑term energy savings and excellent weather resistance, it provides a one‑stop solution to modern buildings’ needs for energy efficiency, noise reduction, and aesthetic enhancement.
