It is available in offline single‑silver, double‑silver, and triple‑silver Low‑E configurations, with argon gas filling to enhance thermal insulation performance. The product’s core principle lies in the selective reflection of infrared thermal radiation, thereby achieving… Transmits light but not heat; provides daylight without raising the temperature. It simultaneously blocks more than 90% of ultraviolet rays, while delivering multiple performance benefits—including thermal insulation, soundproofing, sun protection, condensation prevention, and wind‑pressure resistance—specifically addressing regional challenges such as intense western sunlight and high temperatures in South China, high humidity during the rainy season, coastal salt spray, street‑side noise, and typhoon‑prone conditions at high altitudes. We support nationwide bulk supply and export‑ready solutions, provide comprehensive 3C‑certified and energy‑efficient thermal‑insulation test reports, and ensure compliance with all requirements for construction project bidding and final acceptance.

II. Performance Advantages of Core Products

1. High-performance, energy-saving insulation, perfectly suited to the intense western sun in South China.
   Low‑E coating reflects 70%–95% of solar infrared heat, blocking outdoor heat waves from entering the interior in summer while retaining indoor cool air in winter. With a single‑silver insulated glass unit, the U‑value can be as low as 1.6 W/(m²·K); dual‑silver and triple‑silver configurations further improve thermal performance by 20%–40%. For homes exposed to afternoon sun, this can reduce indoor temperatures by 3–5°C, cutting annual air‑conditioning energy consumption by more than 30% and meeting the energy‑efficiency requirements for green building certification.
2. High light transmission, low glare, and long-lasting UV protection.
   Visible light transmittance ranges from 60% to 82%, providing soft, diffused indoor lighting without harsh mirror‑like glare. It also effectively blocks ultraviolet rays, helping to prevent fading and aging of furniture and soft furnishings, making it ideal for floor-to-ceiling windows and sunrooms exposed to prolonged sunlight.
3. Hollow cavity sound insulation and noise reduction, specially designed for street-facing buildings.
   The 12A/18A hollow air‑gap design, combined with a warm‑edge sealant system, delivers a weighted sound insulation rating of 35–42 dB, effectively attenuating low‑frequency noise from traffic and commercial areas, thereby addressing the challenge of noise interference in buildings located along major thoroughfares and in bustling urban districts.
4. Warm-edge double-seal design, effectively preventing fogging caused by South China’s humid climate.
   It employs a four‑step sealing process featuring 4SG flexible warm edge strips, butyl sealant, and structural adhesive, with molecular sieve desiccant packed inside the hollow cavity. This design is well suited to Guangdong’s high‑humidity plum‑rain season, effectively preventing air leakage, condensation, whitening, and delamination of the insulating glass unit, thereby significantly extending its service life. For coastal projects, thicker tempered glass panes can be used to enhance resistance to salt spray and aging.
5. All-tempered safety substrate, resistant to typhoons at high altitudes.
   The entire pane undergoes uniform tempering, resulting in shatter‑proof fragments with no sharp edges. For high‑rise buildings and coastal areas prone to typhoons, the original glass can be upgraded to thicker 8 mm or 10 mm options, meeting Guangdong’s high‑rise building wind‑pressure resistance standards and ensuring safety and compliance.
6. Multi‑process composite customization, tailored to diverse engineering designs.
   It can be paired with ultra-clear raw glass, laminated layers, curved tempered glass, and gradient colored glazing techniques, and supports custom fabrication of extra-large panels, balancing aesthetics, safety, and energy efficiency to meet the design requirements of high-end villas and trendy public‑building projects.
