We have a clear vision:
Our team intensively analyses the glass requirements of your project and offers you a fitting solution. Each glass pane will be a custom-made product for you.


Suitable thermal insulation, high acoustic control values, a wide range of sun protection options, visual decor highlights as well as reliable protection against burglary and the risk of injury: the steadily increasing demands on modern glazing require an understanding of the material as well as technical know-how for its use in the building – both does FT-Vilstal consider to be part of its expertise.

We obtain our glass panes from renowned suppliers in Germany, from where they reach our production facilities for further processing after adequate testing and quality control.

Feel the nature:
The wood gives your window a vivid naturalness and warmth. Due to the variety of wood types and finishes, a perfect match between the appearance of your window and the interior design can be achieved.

Types of Wood

For the production of our windows and doors we exclusively work with selected wood species from regional forests, which are certified according to FSC (“Forest Stewardship Council”) or PEFC (“Programme for the Endorsement of Forest Certification Schemes”).

In addition to standard types of wood such as spruce, pine, larch or oak, we also process mahogany or eucalyptus. To achieve optimal protection of the wood, it is given a 3-ply water-based coating – naturally stained, oiled or painted according to RAL.

The (colour) choice is yours:
Whether powder-coated in RAL, DB, NCS or as an anodised finish, you can freely design the external aesthetics of your window.

Exterior Finish

The professional coating of our aluminium frames corresponds to the seal of approval of GSB International e.V. and is subject to regular, strict quality controls. There are no limits to the design requests of our customers: we can apply all powder-coated colours in RAL, NCS or DB colours as well as the full range of anodised finishes in silver, bronze and gold.

Is your project located close to the sea or to an industrial site? Professionally processed in accordance with Sea-Proof guidelines, our wood-aluminium systems withstand even the most severe weather conditions.
