Custom-made windows from Bochum
Dieter Lueg Kunststoff-Fenster GmbH is an owner-managed family business from Bochum-Wiemelhausen specialising in the manufacture and installation of custom-made windows. In its own workshop, plastic windows and entrance doors are individually manufactured to order-specific requirements and DIN standards using CNC-controlled machine technology; installation is carried out by the company's own window installers. The product portfolio includes windows and entrance doors made of plastic, aluminium and wood with glass inserts or infill panels, roller shutters in plastic and aluminium, canopies and terrace roofs made of aluminium or stainless steel with acrylic glass or real glass coverings, as well as sun protection systems such as external venetian blinds and awnings. In addition, the company offers consultation in its own showroom, repairs, maintenance contracts for rental properties and an emergency service in the event of break-in and storm damage. Customers include private and commercial builders, housing cooperatives and institutions in the Bochum and Hattingen area. From a two-man joinery taken over in 1961, the company has developed into a master-craftsman business now run by the third generation.
