High-Transparency Energy-Efficient Insulating Glass

Introduction

High-Transparency Energy-Efficient Insulating Glass, also known as Super Insulating Glass, is Xinfuxing Glass's latest high-performance glazing solution engineered for exceptional thermal insulation. Manufactured using our advanced large-area vacuum magnetron sputtering coating technology, the glass features multiple nano-scale layers of metals and metal compounds deposited on its surface. By precisely controlling the thickness of each functional coating layer, it delivers high visible light transmittance while effectively reflecting long-wave infrared radiation (heat), significantly enhancing thermal insulation performance.
This product series is ideal for applications requiring both outstanding transparency and superior thermal insulation, including commercial freezers, refrigerated display cabinet doors, and Passive House projects.

Features

High visible light transmittance: Allows users to clearly observe the interior of cold chain equipment, enhancing product display.
Low surface emissivity: Nearly the Low-E emissivity of triple silver, reducing "cold radiation."
Light appearance color: Neutral color, aesthetically pleasing and comfortable.
Stable processability: Stable film layer; heat treatment and oxidation resistance meet the requirements of deep processing.

Product Application

High-Transparency Energy-Efficient Insulating Glass offers significant value for cold chain applications and energy-efficient buildings. It is widely used in refrigerated display cabinets, commercial freezers, wine cabinets, refrigerated trucks, and temperature-controlled warehouses and industrial facilities, where it helps reduce energy consumption while maintaining stable internal temperatures. In addition, it is an ideal glazing solution for Passive House projects and buildings in cold climate regions, delivering outstanding thermal insulation and long-term energy savings.

Notes

The above performance data were measured using GlasSpec 2500 and calculated in accordance with JGJ/T 151 and GB/T 2680. Thermal performance values are based on an insulating glass unit filled with 90% argon gas.

Visible light spectrum: 380–780 nm; Solar spectrum: 380–2500 nm.

Boundary conditions: Indoor temperature 20°C; outdoor temperature −20°C; indoor surface heat transfer coefficient 3.6 W/(m²·K); outdoor surface heat transfer coefficient 16 W/(m²·K); mean radiant temperature −16°C; solar irradiance 300 W/m².

The above data are subject to a tolerance of ±3%. The tolerance for the U-value is ±0.02 W/(m²·K), and the tolerance for the Shading Coefficient (SC) is ±0.02.
