Family business on Lake Constance – for almost 50 years

Owner-led in the fourth generation

Winkler Technik was founded in 1977 by Dr. Wolfram Winkler in Überlingen on Lake Constance and is led today by Alexander and Veronika Winkler. The owning family is part of daily operations — decisions are short, clear and made with the next generation in mind.

Sales, export, logistics and office

Our team is built around experienced specialists in sales, export, order processing, logistics and accounting. Many colleagues have been with Winkler for over ten years, some for more than twenty — something our customers feel every day on the phone: they talk to people who know the product and understand the market.

This continuity is no coincidence. It is the result of a clear attitude: we treat each other with respect, support training and create jobs that last.

What we stand for

Our task is clear: develop fastening systems for underfloor heating, wall heating and surface temperature control that professionals can trust blindly. What carries us is a mix of craftsmanship, engineering mindset and our connection to the region around Lake Constance.
