Since 1969 Holonite has been the name for composite stone in the Netherlands. As a producer and distributor of, among other things, sills, window sills and wall copings made of composite stone, Holonite has acquired a leading position within the construction and window frame industry.
Holonite serves the Dutch, Belgian, English and German new-build and renovation markets with standard and customised facade and finishing elements, from architect to contractor and from housing association to indirectly the private individual. With the product group of low relief thresholds, Holonite focuses on the window frame industry. Besides being a producer of standard building elements for regular construction, Holonite is increasingly a partner and a thinker with an advisory role in the project. Holonite products are sustainable and Cradle to Cradle certified. Holonite in Tholen currently employs 71 people.
