The International Architectural Festival WAF 2022 was held in Lisbon. The Ukrainian company Aestech (better known as PIK Group) presented at its own stand the technology of glass with higher stiffness. This is the company's own patented innovative development. It allows the use of large format glass without a supporting frame. Profiservice has been successfully using this technology for more than 2 years. We are proud to be always ahead with our partners Aestech.
