Terrace Roofs – Expand Your Living Space

With the right roof for your terrace and balcony, you can truly make use of your outdoor space. Düpmann Aluminium offers Terrace Roofs that keep you protected from windy and rainy days from the first days of spring until well into autumn. The roofs span up to 7m wide and 6.4m deep and supported by only two pillars. They are elegantly designed with smooth, closed surfaces and concealed screws. Due to extensive pre-manufacturing works, installation is easy and fast. The uninsulated aluminum profiles are delivered in a ready-to-build construction kit. Düpmann Glasshouse series is the ideal alternative to a highly insulated conservatory.

Canopies and Carports – Protecting Through All Weather Conditions

Düpmann Aluminium offers Canopies in nearly 50 standard models, however, customised designs are also possible. The Canopies are available in aluminium, stainless steel or all-glass. With Düpmann Aluminium Canopy, you will not get a mass product, but individually handcrafted products with excellent quality and accurate production.

Available in a variety of models and designs, Düpmann Aluminium Carports protect and shelter your vehicles. They are attractively designed with glass, coloured acrylic or functional GRP Roofing. Accessorise the Carports with LED or Halogen spotlights to create that warm and cosy atmosphere.

Sliding & Folding Doors – Enjoy Unobstructed Outdoor View From Inside.

Enjoy your seasons with Düpmann Sliding & Folding Doors. They are designed with slim aluminum profiles and large glass surfaces. During summer, the un-insulated doors allow you to open up your living space where the sun awaits you in your garden. During winter, the insulated doors protect you against the cold.

Düpmann Sliding Doors can be placed underneath balconies, terrace roofs, or used as room dividers. The systems are available with window glazing of up to 24mm and usage of up to 4 tracks.  Düpmann Folding Doors can be folded either inwards or outwards with a large opening width.

Vertical Windows – With Us, It’s Easy To Move Up.

Düpmann Vertical Windows can be moved upwards and adjusted at any height without the need for additional stoppers. The windows are fitted with double springs for weights up to 75 kilograms. With optimal use of space and ease of usage, there many possibilities for applications – kiosks, reception and sales counters, in restaurants, private spaces, pharmacies, or grandstand fronts.
