Under the European Union's updated Energy Performance of Buildings Directive (EPBD), Bulgaria is actively reforming its national building codes (notably Ordinance No. RD-02-20-2 on the energy performance of buildings). By targeting near-zero energy building (NZEB) status for new and deep-retrofit projects across key economic hubs like Sofia, Varna, Plovdiv, and Burgas, the construction industry faces a critical technical bottleneck: reducing window and curtain-wall thermal transmittance. Historically, achieving a U-value of under 0.8 W/m²K required heavy, triple-glazed systems that placed severe structural demands on window frames and building facades.
Unlike standard double-pane or triple-pane gas-filled glass, Vacuum Insulated Glass (VIG) features a microscopic vacuum space (typically 0.1mm to 0.3mm wide) between two panes of tempered glass. Sealed under high vacuum pressures (<10⁻⁴ Pa), the molecular density of the space is reduced to the point where thermal conduction and convection are virtually eliminated. Small, high-strength micro-spacers prevent the glass panes from collapsing under atmospheric pressure.
The result is a glazing panel that is significantly thinner (typically 8.3mm to 12.3mm) and lighter than conventional triple-glazing, yet achieves a center-of-glass U-value as low as 0.5 W/m²K to 0.6 W/m²K. This thermal profile is equal to or better than a solid insulated wall, allowing architects in Bulgaria to specify expansive glass elements without compromising on thermal efficiency.
Globally, the demand for VIG has surged as developers align their designs with green certifications such as LEED, BREEAM, and DGNB. Zerothermo Technology Co., Ltd. (a subsidiary of CBVAC Group) operates one of the largest modern manufacturing centers for vacuum technology products. Our production base in Nanchong, Sichuan Province, leverages industrial-scale vacuum sealing systems to ensure consistent vacuum integrity and structural durability. This enables us to provide bulk supply chains to construction projects throughout Europe, minimizing lead times and providing reliable pricing structures for Bulgarian construction consortia.

Importing structural materials into Bulgaria requires strict compliance with European Committee for Standardization (CEN) codes. Zerothermo’s VIG line holds complete CE marking and undergoes testing in line with EN 1279 (Glass in building - Insulating glass units) standards. In addition, our systems are optimized to handle local weather patterns—from the humid subtropical summers of Varna and Burgas to the snowy, alpine winters of the Rila-Rhodope massif.
