ABOUT US
We’ve been in the industry for over 30 years. We were here yesterday, we’re here today, and we’ll be here tomorrow.
OUR History
Since 1995, Alpena Group has stood as a symbol of trust, quality, and sustainable solutions in the construction industry. Founded in Ankara’s Ostim industrial zone, our company began its journey by supplying accessories and auxiliary components for PVC, aluminum, and wooden joinery systems. Over time, we expanded our product portfolio and specialized in movable glass systems.
From day one, we have remained committed to innovation—constantly evolving to meet the changing demands of the sector through forward-thinking approaches and continuous development.
Today, under our brand KAPGA, a proud sub-brand of ALPENAGRUP, we provide both production and knock-down delivery solutions in the field of architectural movable glass systems. With our 3,000 m² indoor production facility, cutting-edge technology infrastructure, and a skilled team, we offer tailored solutions for each project—designing and manufacturing systems that are aesthetic, functional, and built to last.
With nearly 30 years of experience, a strong supply network, and a customer-focused mindset, Alpena Group delivers not just products, but lasting value. We take pride in being a trusted business partner for architects, dealers, and installers across Turkey.
We are committed to maintaining our leadership in movable glass systems, shading solutions, and customized architectural automation through continuous innovation and unwavering quality.
