About us

CEMBRA Inc. is the sole importer of RIEDER KG products in North America.

Our goal is to provide highly energy efficient windows and doors directly to the consumer at an affordable price. Through CNC manufacturing we can fabricate any desired size at low cost and liberate the architect from the constraints of stock size products. Superior wood craftsmanship meets a high degree of automation. All orders are shipped straight from the factory to the point of usage, eliminating the need for storage and additional handling and thereby creating more savings for the customer.

We offer tilt + turn windows, various types of interior and exterior doors and large and small sliding door solutions which allow for a seamless transition between the indoors and any outdoor area.
Our windows have been approved by the Landmarks and Preservation Commission of New York City for usage in historic restoration. Please contact us with details about your unique project and we will do our best to exceed your expectations.

RIEDER KG is based in Austria and has been a family owned business since 1945. The company is manufacturing very high quality windows and doors as well as being involved in the construction business.
