Whether they open onto the world or they close upon state secret, many doors at the Pentagon are signed DE LA FONTAINE.


    You know that DE LA FONTAINE is not just a manufacturer. We are visionaries, inventors and designers. We do not produce doors on an assembly line, but rather create hospital doors that comfort and school doors that protect; office doors that work hard and prison doors that isolate; hotel doors that welcome and residence doors that open up onto life, peace and harmony. 

    And it is with this approach, one which embraces the world of our clients, that we have gained the confidence of innovative architects, demanding businesses and prestigious institutions all over the world.
