Finstral has been developing and manufacturing plastic and aluminum window frames, house doors and glass facades since 1969. With 14 production locations, more than 1,600 employees and a production of more than 800,000 frames per year, Finstral is among the European market leaders in its segment. With Studio Hoofddorp and Studio Apeldoorn, Finstral has 2 branches in NL. Finstral is known for its through-and-through colored profiles with embedded wood grain without foils and has the largest window frame assortment in Europe due to its modular window systems. Materials, colors and shapes can be infinitely combined with each other because Finstral produces everything itself from raw material to finished product, even the glass. In this way, a window frame can be put together completely as desired.
