Tempered Insulated Freezer Glass

Advantages: Energy Efficiency & Premium Quality

1. Outstanding Energy-Saving Performance

VGC Tempered Insulated Freezer Glass adopts a high-performance double-glazed or triple-glazed insulated structure, filled with dry inert gas (argon or krypton) between the glass layers. This specialized design effectively blocks heat transfer, minimizing the thermal bridge effect and reducing the load on refrigeration compressors. Compared with LOW-E energy saving glass, our insulated freezer glass can reduce energy consumption by 30%-45%, significantly lowering the long-term operating costs for end-users. The low-emissivity (Low-E) coating option further enhances thermal insulation by reflecting infrared radiation, ensuring stable low-temperature environments inside the freezer without excessive energy input.

2. Superior Mechanical Strength & Safety

The base glass of VGC products is processed through full-tempering technology, which increases its surface strength by 3-5 times compared to annealed glass. It can withstand impact from heavy objects (conforming to ISO 12543-1 standard) and resist thermal shock caused by sudden temperature changes (from -40℃ to 80℃ without cracking). In case of breakage, the tempered glass shatters into small, blunt-edged fragments, eliminating the risk of sharp cuts and ensuring user safety. Additionally, the glass is equipped with a durable sealant system that maintains structural integrity even in extreme low-temperature environments, preventing air leakage and condensation.

3. Excellent Durability & Longevity

VGC Tempered Insulated Freezer Glass is designed for long-term use in harsh refrigeration conditions. The high-quality sealant (polyurethane or butyl rubber) used in the insulated structure has excellent resistance to aging, corrosion, and low temperatures, ensuring no seal failure for more than 15 years. The glass surface is also optional with anti-fog, anti-scratch, or anti-UV coatings, which not only maintain clear visibility for display freezers but also prevent surface damage and discoloration caused by long-term use and environmental factors.
