The ultra-high insulation vacuum glass "Super Spacia(R)" has won the 2017 Energy Conservation Grand Prize.

Unparalleled insulation performance. Vacuum technology has evolved to this point. The common understanding of insulating glass is about to change.

The ultra-high insulation vacuum glass "Super Spacia" is a product that significantly improves the insulation performance of the vacuum glass "Spacia," which our company successfully commercialized for the first time in the world. The spacing of the micro spacers that maintain the vacuum layer between the two glass panes has been expanded from the conventional 20mm to 28mm. By halving thermal conductivity, the insulation performance has been improved by approximately 54% compared to the conventional "Spacia." 【Features】 ■ Thanks to the unique vacuum technology of Spacia, high insulation is achieved with just one Low-E glass pane. As a result, it boasts high visible light transmittance. ■ By achieving the high insulation of typical triple-glazed glass at less than half the thickness, it can accommodate various applications for both residential and non-residential buildings. *For more details, please refer to the PDF materials or feel free to contact us.

Only the glass will be replaced. It contributes to energy savings with high thermal insulation performance and anti-condensation effects.

Japan Glass's "Spacia" is a vacuum glass that achieves about four times the insulation performance of single-pane glass, thanks to its vacuum layer and Low-E glass. It allows sunlight to enter while preventing warmth from escaping indoors, helping to reduce air conditioning costs. Additionally, its structure is less susceptible to external influences, which helps suppress the occurrence of condensation. There is a diverse lineup including "Spacia Cool," which cuts summer solar heat, "Spacia Quiet," which reduces noise, and "Spacia 21," a multi-layer vacuum glass. 【Features】 ■ Four times the insulation performance to maintain a comfortable indoor temperature ■ Reduces window glass condensation for cleanliness ■ Allows sunlight in while retaining its warmth ■ Contributes to energy savings by reducing heating and cooling costs ■ Only the glass needs to be replaced, allowing the existing frame to be used *For more details, please refer to the PDF materials or feel free to contact us.
