About Us
Unparalleled historical craftsmanship
In the tradition of fine French homes, windows are considered much more than a simple framework; they represent precious effects that grace a façade.
For five decades, I have had the privilege of redefining beautiful homes – focusing on the artisanal tradition of crafting excellence.
The transmission of our exceptional know-how through the years has allowed us, today, to become one of the leading French companies for windows.

Our core values
Craftmen at heart
When Henri Janneau founded his company in 1973, he set in motion a vision of craftsmanship that looked to the future and made no concessions to traditional know-how. His project is built day after day on 100% French manufacturing.
Thanks to his passion for joinery, the small workshop located in the heart of the Loire Valley has grown to become a major player throughout France. With 100,000 windows and doors produced every year and 5 production units, the men and women who make up Groupe Janneau have never forgotten their artisan’s soul. From design to installation, they put all their expertise into your project, with durable products made in France.
