Natural light in house

How does every window become a panoramic window? How do we replace frames, mullions and sash bars that break up the view outside and reduce the incidence of light? How do we still manage to create a sturdy, airtight window with excellent levels of stability? The answer was an innovation: Clara windows, the world‘s first frameless windows with a casement made entirely of glass. The elegant, refined design perfectly complements contemporary architecture, fills rooms with light and offers almost unlimited freedom of design.

Sales Manager France

“I am in charge of the commercial strategy on the French market and I am responsible for development and negotiations with distributors. In addition to analyzing the structure and segmentation of the market, my project is to develop the network of prescribers. I am also in charge of negotiations, referrals and loyalty building with central purchasing organizations. Thanks to my previous managerial experiences in the fields of carpentry and sun protection, this market knowledge has become second nature to me and I have acquired the conviction that customer satisfaction must be at the heart of our concerns.”


Julien Brugmans

Sales Manager Benelux

“Over the past few years, I have had the opportunity to work with different players in the construction industry and to support them in promoting new products in new markets. Prior to joining Clara, I helped launch HALIO, AGC’s dynamic and intelligent lens. I was also responsible for the business development of sun protection solutions in the United States. Within Clara, I am responsible for the development and management of the commercial network in the Benelux. I am at your service so that we go through your project together and to assist you in the selection of the best architectural solution.”

« Over the past few years I have had many exciting times finding interesting solutions for projects with builders, architects and dealers. As a qualified carpenter, I know my job and as a passionate advisor I understand your expectations and your needs. With over 20 years of experience in the window industry, I immediately recognized that Clara’s innovative windows and sliding doors offered unique design possibilities. While waiting to advise you on the design of your future projects, you can contact me with any questions. »


Pierre Schneider

Sales Director

« After many years working in an executive position at AGC, the group then provided me with the opportunity of embarking on an exciting adventure in 2017.

As the project manager responsible for industrial production, it was my task to optimise the industrialisation of a new type of window so it could be marketed on a wider scale: it concerned Clara windows, the world’s first frameless window made entirely of glass.

I had to learn completely different professions such as window fabricator, installation technician and salesman to this end. I feel this is all immensely enriching.
And where a product as fascinating as Clara is concerned you are never lacking in motivation! »
