About KCT
KCT GmbH & Co. KG, based in Rosenfeld (Baden-Württemberg), manufactures windows, roof hatches and portholes with HartGlas® insulating glazing as well as locking technology for vehicle construction, in particular for expedition vehicles and the motorhome and caravan industry. The HartGlas® windows are flush with the outer wall, steel-reinforced, double-sealed, burglar-resistant, seawater-resistant and withstand air pressure differences at high altitudes without a valve. Production combines CNC technology and craftsmanship; the corner joints of the plastic frames made of UV-stabilized plastic with thermal insulation chambers are welded, so that custom sizes are also possible. The product range also includes the insect and sun protection roller blind (ISR), the Syslock® locking system, door seals and installation gauges. In-house, KCT offers inspection and reconditioning of its windows. International spare parts service is provided via a network of more than 500 service partners in Europe, the USA and Australia; delivery is worldwide.
