Lukasz Jozefecki

Technical Director
Lukasz Jozefecki is the founder of the company and a specialist in high-performance architectural window and door systems. With more than 17 years of experience in the industry, he has worked with some of Europe’s leading manufacturers, primarily in research and development, gaining a deep understanding of the engineering, performance, and design behind modern glazing systems.
 
Raised in Poland in a traditional family that valued craftsmanship and building things to last, Lukasz developed an early connection to the construction industry. His professional journey began with hands-on work in construction and manufacturing, giving him practical insight into how buildings come together — from structure to the smallest architectural details.
 
Today, he works closely with architects, builders, and homeowners to deliver carefully selected systems that combine technical precision, refined aesthetics, and long-term performance. His goal is simple: to help bring ambitious architectural visions to life through thoughtful design and reliable solutions.
