About Fritz Robering
Fritz Robering GmbH & Co. KG is a manufacturer of accessory profiles for windows, doors and installation based in Vlotho-Uffeln (North Rhine-Westphalia). The product range comprises more than 100 different profiles, including window glazing beads, flat strips, chamber profiles, reveal lining profiles, angle profiles, decorative profiles, ornamental parts, aluminium/plastic conversion profiles, secondary glazing profiles DF, seals and PE foam adhesive tapes. Production takes place in the company's own extrusion operation since 1965, and since 1970 also using the co-extrusion process of rigid and soft PVC for profiles with soft sealing lips. The company's own coating lines (since 1994) enable the finishing of profiles with decorative foils (Renolit, Cova, Hornschuch) as well as coating of blanks using the hot-melt process. In the in-house toolmaking department with CAD design, new profile extrusion tools are manufactured and existing tools are adapted and repaired – also on customer order. The profiles are made from rigid and soft PVC virgin material and are available in many colours and decors matching the systems of major window system suppliers such as VEKA, Rehau, Schüco, Gealan or Salamander. Customers are window and door manufacturers as well as window construction, door construction and window modernisation; logistics are handled by freight forwarder and parcel service.

Materials & Processes
Rigid PVC
Base material of the standard profiles in various colours with UV and weather resistance, virgin material only.
Soft PVC
For co-extruded soft sealing lips on window glazing beads, flat strips, chamber profiles and seals.
Aluminium
Base profile of the conversion profiles (e.g. NEU DL natural colour) for converting old wooden windows to insulating glass.
Silicone
For silicone seals (JQA/JQS/JOA) for routing-in or self-adhesive.
Epoxy resin
Casting material of the painted ornamental parts for window glazing beads.
PE foam
1 mm thick adhesive tape for self-adhesive bonding of the profiles for outdoor and indoor use.
PVC (foamed)
Material of the decorative profiles with smooth surface.
Decorative foil coating
Finishing of profiles with Renolit, Cova and Hornschuch decorative foils, also at short notice in-house.
Hot-melt coating
Coating of various blanks with different decorative materials using the hot-melt process.
