S Plan®



The flat flush generation of windows



Innovations result from the demand to achieve perfection in technology and design and make everything easy. To be able to do this one has to be consequent and stick to the essentials. The integration of these features has to reveal a highly aesthetic form of expression. The demand for clear and precise form leads to the modern innovative development of the construction. The result is outstanding for its unadorned and sovereign realisation of the demands–the flat flush clear unit with elegance and purity of line.


The new S Plan® generation of windows enables planers and prospective clients to achieve new designs using innovative materials such as wood and glass. Just wood alone offers manifold possibilities for constructive integration with glass as material. The flat flush glazing system to the outside and the construction to the inside offers even greater freedom in design for the entire project. The use of high stabile and deformation-resistant construction timber is the basis for precise design and integration with glass as material. The development of frame covering glazing was first made possible as a result of the properties of wood as material. Glass offers additional weather protection for the opening leaf and, as a consequence, supplements this aesthetic constructive union. The frame construction and the opening leaf form a single flat flush unit.
