The Management Board

The two managing directors enjoy spending their free time where our primary raw material, wood, comes from – in the forest!

Our family-run company with around 100 employees
manufactures windows, large sliding elements and exterior doors in Gerolzhofen, in the Franconia region of Germany.

We specialize in solid timber and timber-aluminum constructions with the highest quality,
unsurpassed durability and a huge variety of designs.

Your full satisfaction with our products is our goal!

We are a modern
industrial craft manufacturer.


Industrial because we naturally manufacture our components in accordance with industrial standards, using modern CNC technology.


Craft manufacturerbecause the individual parts for each window and each of our exterior doors are not assembled by machines, but by the hands of highly qualified specialists – and have been since 1906.  This tradition of more than 110 years of craftsmanship drives us to achieve – or even surpass – the feel and the quality of a handmade unique item also in serial industrial production.



We think and act in a sustainable manner. 
Döpfner is


To assume responsibility for the environment and for a sustainable future is not just an empty phrase at Döpfner, but a company culture lived every day.  The raw materials we use are renewable timber – exclusively from controlled regional forestry – and recyclable aluminum.  Electricity is generated by the sun on the workshop roofs and timber waste is a source of CO2 neutral heat.
