DuoLine Vorsatzschale (Shell facing framework) front doors

Nothing's impossible. With our DuoLine system solution, we have developed a technology, which opens up whole new possibilities when it comes to design and customization.

Here's the clue: you can design the inside of your front door completely different from the outside and therefore integrate two (maybe completely different) looks and feels into one front door. Even ambitious combinations of materials, such as textured, matured wood on the outside and glossy varnish on the inside can be integrated seamlessly with our DuoLine technology. Whether you or your customers simply want to choose multiple materials and surface options or want to stay current on the newest design trends: DuoLine is your solution.

And because the solid base of the door is decoupled from the shell, you are not making any compromises on quality, form stability, resistance and functionality, as well as thermal insulation, sound insulation, density or safety.
