Biography
Pekka Nieminen has spent 30 years in the glass industry, including 23 years at TAMGLASS–GLASTON Corporation, where sales and service teams across Europe, the Middle East, and the APAC region were led by him. Between 2022 and 2025, the role of General Director at the Glaston Tianjin workshop was undertaken by him. At the beginning of 2026, he joined LEADUS TECH, where the position of Vice President for Global Sales has been assumed. He is married and is the father of three daughters. Currently, he has four grandchildren, with the family expected to grow to five later this year. Throughout his life, team sports such as football and ice hockey have been actively practiced, while in later years, a stronger focus has been placed on golf.
Presentation
Early vacuum insulated glass technology relied on glass solder to seal edges and pump-out-ports for vacuum extraction. However, commercialization revealed significant drawbacks, including lengthy production cycles, limited scheduling flexibility, higher risks of leakage due to pump-out-ports, and compromised aesthetics.
The industry has increasingly shifted toward pump-out-port-free vacuum insulated glass, utilizing sealing in a vacuum environment to address these challenges. However, the high melting temperature of commonly used glass solder has made it difficult to manufacture fully tempered glass, failing to meet regulatory standards in many regions. Additionally, the rigidity and brittleness of glass solder joints increase the likelihood of leakage under stress or deformation.
To overcome these limitations, LEADUS developed an innovative low-temperature metallic soldering in vacuum environment process (No pump-out-ports) and, in 2019, became the first to achieve large-scale production globally. This method enables sealing at temperatures far below the annealing point of tempered glass, ensuring compatibility with fully tempered glass. The flexibility and ductility of metallic solder significantly improve durability under stress and deformation, minimizing the risk of leakage. Additionally, sealing in a vacuum environment eliminates the need for individual vacuum pumping, greatly enhancing production efficiency and product aesthetics.
This breakthrough represents a significant advancement in vacuum insulated glass technology, delivering improved performance, faster production, and compliance with international standards.
