Low-E Glass for Curtain Walls

Yehauxuan Low-E Glass for Curtain Walls achieves dual energy savings—heat insulation in summer and thermal insulation in winter—through precise control of spectral transmission. Combined with ultra-clear glass and a multi-cavity hollow structure, it balances light transmission with sound insulation and UV protection, making it suitable for various high-end commercial complexes, landmark buildings, and high-quality residential curtain wall applications, meeting green building energy efficiency standards.

Core Technologies and Processes

Low-E Glass for Curtain Walls utilizes offline Low-E coating technology, achieving an emissivity of ≤0.15 through a multi-layer composite film system (including a high-purity silver layer). The film layer is sealed within the hollow cavity, preventing oxidation and corrosion, ensuring a lifespan that matches its sealing performance. Combined with Yehaoxuan's precision manufacturing system for curtain walls, the glass cutting accuracy reaches ±0.5mm, the edge grinding process is standardized, and it seamlessly integrates with the curtain wall system. Its wind pressure resistance and structural stability exceed national standards.

Core Performance Advantages

1. Energy Efficiency

Low-E Glass for Curtain Walls blocks over 80% of near-infrared solar heat in summer, achieving a shading coefficient (SC) as low as 0.3-0.5; in winter, it reflects indoor far-infrared heat radiation, with a heat transfer coefficient (U-value) as low as 1.0-1.8 W/(㎡·K), resulting in 40%-58% energy savings compared to ordinary glass.

2.Optical Adaptability

Visible light transmittance reaches 60%-80%, with high-transmittance, medium-transmittance, and low-transmittance models available. The ultra-white film version has a light transmittance of ≥92%, balancing natural lighting and privacy protection. Outdoor reflectance is controlled at 10%-30% to avoid light pollution.

3.Additional Protection

Blocks over 90% of ultraviolet rays, delaying fading and aging of indoor furniture and decorations; the hollow structure filled with inert gas (such as argon) provides significant sound insulation while improving thermal stability.

Scene Adaptability

Optimized design for different climate zones: Low-E (SC≤0.5) shading type is selected for hot regions, focusing on heat insulation; high-transmittance type (light transmittance ≥70%) is selected for cold regions, enhancing passive heat gain; double-silver/triple-silver film systems are suitable for areas with large winter-summer temperature differences, balancing thermal insulation and heat preservation needs. Supports integration with exposed/concealed frame curtain wall systems, and can integrate micro-ventilation windows and intelligent control systems to achieve automatic closing functions such as wind and rain sensing.

FAQ

1. Can Yehauxuan Low-E Glass for Curtain Walls be used as a single piece?

No. It uses an offline coating process, where the coating layer must be sealed inside the hollow/laminated glass cavity to prevent oxidation damage. Simultaneously, the composite structure enhances energy efficiency and safety performance.

2. How to identify genuine Low-E glass?

① Check if the 3C certification mark includes the "Low-E" label; 

② A light blue/gray coating layer is visible when viewed from the side; 

③ Hold a lighter close to the glass; a light blue flame reflection is visible (ordinary glass does not exhibit this phenomenon).
