GreenVac One is one-step molding process to heat,vacuum and seal the glass in a special continuous vacuum chamber. Compared with the two - step method, the vacuum glass surface or corner produced by this process have no vent and protective cap, which is easy to be accepted by the market. The glass output and quality level have been greatly improved and the energy consumption in the production process is less. At present, the maximum size is 2500mm x 1500mm. and the heat transfer coefficient reaches 0.57 W/m2`k, which is better than theEuropean passive room standard of 0.8 and the sound insulation capacity reaches more than 37 dB.
The application areas wil be architectural interior, exterior decoration, curtain wall installations and glass door for refrigerator, etc.
Compared with the one - step method, GreenVac Two is a protective cap in the corner of glass to push the air out. But GreenVac Two can be more flexibility in size and shape. At present, the maximum size is 3300mm x 2000mm. The heat transfer coefficient reaches 0.45 W/m2`k,which is better than the European passive room standard of 0.8 and the sound insulation capacity reaches more than 37DB.

Thermal Performance:
Heat Insulation: This is likely the core feature of GreenVac Glass. It likely utilizes vacuum insulation similar to vacuum insulated glass (VIG) and vacuum insulated building-integrated photovoltaics (BIPV) glass. The vacuum creates a barrier that significantly reduces heat transfer between interior and exterior environments. This can lead to:
Lower energy consumption for heating and cooling a building.
Improved building thermal performance.
Sound Insulation: The vacuum cavity may also act as a barrier to sound waves, offering some soundproofing properties. This could be beneficial for buildings in noisy environments or areas requiring quieter spaces.
Lightweight Material: While vacuum insulation can add some weight, GreenVac Glass might still be lighter than conventional double or triple-paned windows due to the reduced need for thick glass layers. This could potentially reduce structural loads on a building and be easier to install in certain applications.
Condensation Resistance: The reduced air circulation within the vacuum insulation can minimize condensation on the inner surface of the glass, especially in humid climates. This can be advantageous for buildings in areas with significant humidity swings or where condensation control is important.
Durability: Vacuum glass is durable and long-lasting, with the vacuum-sealed gap protected from external environmental factors such as moisture, dust, and pollutants. Properly manufactured vacuum glass units can maintain their performance over many years of use.
Energy Efficiency:
Reduced Heat Transfer: GreenVac Glass likely utilizes vacuum insulation, similar to vacuum insulated glass (VIG) and vacuum insulated building-integrated photovoltaics (BIPV) glass. This vacuum creates a barrier that significantly reduces heat transfer between interior and exterior environments. This can lead to:
Lower energy consumption for heating and cooling a building.
Improved building thermal performance.
Environmental Benefits:
Reduced Reliance on Fossil Fuels: By enhancing energy efficiency, GreenVac Glass could contribute to a building's reduced reliance on fossil fuel-based energy sources for heating and cooling.
Sustainable Material: Vacuum insulation offers a potentially sustainable approach to energy savings in buildings.
