    Triple-layer glass composed of 4Low-e/14 TGI Ar/4/14 TGI Ar/4Low-e, Ug=0.6 W/m2K


    Three seals are integrated as standard, of which two are in the window overlay and one is below the glazing bar.


    Innovative window profile of laminated wood with a built-in insulating rigid polyurethane foam, which provides high strength, stability and torsional rigidity of the window. With built-in insulation a lower heat transfer is achieved for the frame.

    Rain protection profile

    Designed to protect the lower, most exposed part of the jamb and casement from the effects of weather. Pulled from the inside of the profile, the drip edge does not constitute a thermal bridge. This fact contributes to improved thermal conductivity values.

  • Wood More

    Being functional and sustainable, modern architecture is also environmentally friendly. With their modern appearance and technical characteristics, windows made of wood provide the best choice for new generation low-energy, passive and energy positive residential buildings.

    Organic, beautiful and renewable, wood is the only material to store CO2 in its structure and thereby protect the environment and contribute to your indoor well-being. Constantly regenerating from the soil, water, air and sun, it connects you back to nature. Being alive and breathing with us, wood is constantly adapting to the weather conditions.

    Available in different thicknesses, our windows are made of high-quality laminated wood including spruce, fir, larch, pine, oak or meranti, and always with continuous strips on the visible sides. Several combinations of different wood types are additionally available.
    The selection and processing of wood are done according to EN 942; multilayer laminated profiles without knots are dried to a moisture content of 13% +/-2%.

  • Colour chart More

    "Wood is beautiful; maintaining and caring make it eternally yours."
    Nowadays, wooden elements can be spiced up with many colours and shades adding up that final touch to the exquisite appearance of your home.

    You can choose from a wide range of colour coatings shown in both our own and RAL colour charts. To grant a long servicing life of your window, we only use environmentally friendly, water-based translucent and covering paints.

    SURFACE TREATMENT: Triple coating including basic impregnation and intermediate layer applied by dipping, and final coating applied by spraying. All our paints are acrylic-based. Shades are available as shown in our own or RAL colour chart, or based on your sample
  • Hinges More

    Modern windows are usually equipped with hinges designed for combined opening, allowing wide opening or tilting and featuring standard blocking at the tilt position. As a standard, LEOPOLD FENSTER windows are equipped with robust, high-quality hinges supplied by ROTO; the ROTO NT hinges are silver-passivated, featuring covering caps; their carrying capacity is a max. 130kg. The hinges can be upgraded to the RC2 security level.

    Opt for hidden hinges to accentuate the beauty of wood.
  • Security More

    Bad quality and the vulnerability of doors and windows are opening the only way for burglars to enter your home. For this reason it is of utter importance to choose such woodwork that provides high-level security.

    Thanks to the use of quality materials, precise manufacturing and fittings supplied by renowned manufacturers, LEOPOLD FENSTER windows provide a high level of protection against damage and burglary already in their standard versions. With their fittings upgraded, appropriate safety glazing and security handles installed, LEOPOLD FENSTER windows can provide a security protection level compliant with the RC2 standard.

    Security is a prerequisite for a comfortable and relaxing stay, and actually one of the basic needs of each individual. Wooden windows may therefore raise many doubts; however, since wood offers a greater resistance to fire even in comparison with concrete, wooden windows prove to be the safest option in case of fire. Withstanding higher loads than concrete, wooden parts also provide great protection in the event of demolition. 
  • Handles More

    As standard, LEOPOLD FENSTER windows are fitted the Hoppe ATLANTA handles. These feature a SECUSTIC security system with a special security clutch integrated in its mechanism to prevent any kind of movement of the handle from the outside and thus any opening of the window by force.

    Convenient to hold and operate, these high-quality handles are available in a variety of materials and colours.

  • Insulation More

    Passive construction is building the future.

    Being functional and sustainable, modern architecture is also environmentally friendly. With their modern appearance and technical characteristics, windows made of wood provide the best choice for new generation low-energy, passive and energy positive residential buildings.

    As the main advantage of Leopold Fenster insulating window frame, its low heat transfer value stands out, while the window's overall mechanical properties remain the same. Compared with a conventional full wooden window frame, heat losses may decrease by 70%. As a result, the difference between the heat transfer values of the frame and the glass is heavily reduced in comparison with conventional wooden windows; this brings a much greater thermal insulation homogeneity of the window as a whole. It is precisely this homogeneity that prevents the formation of moisture on the inside with all there-related inconveniences and brings a longer service life of the product as a result. What all this contributes to is a healthier living environment which is extremely important; namely, with thermal characteristics improved and the formation of thermal bridges prevented, the risk from harmful mildew which might nestle in the furrow of the window frame, is substantially reduced.

    Furthermore, the windows that feature an insulating profile designed by Leopold Fenster are categorised as a product with minimal impact on the environment and record an excellent carbon footprint balance. Being both organic and renewable, wood requires little energy for processing. In addition, carbon dioxide is conserved for the life of the end product produced from wood, rather than released into the atmosphere when burnt. In terms of environmental care, a further major advantage is the use of rigid polyurethane foam as the insulating medium. This solution proves particularly ecological, much in contrary to the comparable market-available profiles using conventional PU foam. The RDX-040 polyurethane system on which the integrated rigid polyurethane foam is based contains a polyol component produced from canola, while older generation polyols are produced from petroleum. To make the final product as environmentally friendly as possible, water is used as the physical blowing agent instead of any air-polluting physical blowing agents.
