Statement: The success formula of the Gretsch-Unitas Group is the same today as it was 90 years ago. The easy operation of windows and doors when you want has become a matter of course to us. That this is so can be attributed in some measure to the Gretsch Unitas Group. Since its founding, it has lead the market and continually improved it through its product policies. Its guiding principle has always been directed toward making the opening of windows and doors technically better, easier and safer than ever.
