Welcome at Holonite

Holonite has been the number one company for composite stone in the Netherlands since 1969. As a producer and distributor of thresholds, window sills and wall covering elements made of composite stone, Holonite has occupied a leading position in the construction and window frame industry since 1969. Holonite provides products for the Dutch, Belgian and German new-build and renovation market, with standard and customised façade and finishing elements. Holonite deals with everyone from architects to contractors and cooperative housing associations to private individuals on an indirect level. Holonite is focusing on the window frame industry (aluminium, plastic and wood) with its range of low-relief thresholds.

In addition to being a producer of standard building components for regular construction, Holonite frequently serves as an expert partner and advisory coordinator on projects. We constantly seek to push our boundaries and hone our expertise by producing custom-made contemporary façade elements, thereby enabling us to give every building its own identity while working in cooperation with our target groups.

Holonite products are sustainable and Cradle to Cradle certified. Holonite has the aspirations to continue to develop and improve as far as corporate social responsibility is concerned. Sustainability is the underlying factor that drives our organisation forward.
