Kumij - uPVC

Leading manufacturer of uPVC window frames.

Kumij - uPVC

Kumij, founded in 1955, is a leading manufacturer of uPVC window frames which delivers (and assembles, if required) its window frames throughout the Netherlands. The high-grade uPVC window frames are used in renovation and new construction projects for housing associations, contractors, architects and homeowners associations.

Project organisation

Kumij offers flexible project organisation with more than 125 employees and has years of experience in delivering custom work. The project-driven approach and responsiveness to the client's wishes are the basis of efficient collaboration. Think, for example, of profiling, detailing and structural integration, but also of construction coordination, keeping residents informed, and delivery.

The window frames are constructed from Profine profiles and they meet the highest standards of sustainability, strength, insulation and safety. Our extensive selection of profiles and colours offer enough options to combine efficiency with aesthetics.
