The new window system has a wood width of only 68 mm throughout. The face width is 110 mm in double seam. The special innovation: The fabricator can build a complete window with a 68 mm x 68 mm wood cross-section. Frame, sash, transom or mullion - all components can be made in 68 mm. All common opening types and window shapes are possible.
Due to the higher proportion of glass and the narrow face widths, Mira TWT offers improved U-values. In terms of break-in resistance, a classification in class RC 2 is envisaged. Tests are currently being carried out for driving rain resistance, wind load, air permeability and impact resistance, and at least the standard values will be achieved here.
Continuity up to an all-wood window
For the first time, it is also possible to produce a wood width of 68 mm at the bottom of the frame in the area of classic wooden windows by means of a new construction of the Gutmann Spree TWT rain protection rail and a windowsill rebate of 30 mm - including correct installation of an aluminium window sill.

The optimised profile geometry for CNC machine technology and an optional glass bonding for large elements are characteristic for the production of the new window. Instead of the previously used turn holder, a clip holder is now used, the sash of the Mira TWT only has to be clipped on, turning by 90 degrees during installation is no longer necessary. The manufacturer does not require any major investments for the production in the workshop, they can work with extensions of the tool stock. Therefore, no special training is necessary, the system is self-explanatory.

"With the new system, we are clearly in line with the trend," Martin Rauscher, Managing Director of Zuani TWT, says, "we are convinced that the new system will be well received by the market - enquiries from users have already come in." The experts of both companies have combined their respective know-how and the result is the new Mira TWT, whose name already symbolises the joint development. Rauscher: "For us, the new wood-aluminium window is another milestone in the more than twenty years of cooperation with Gutmann, which in the past has already produced innovations in rain protection rails or sash cladding profiles."
Responding to market demands
Gutmann Managing Director Arnd Brinkmann reports on enquiries that are now being answered with the new development: "With this innovation, we are responding to market demands: Investors, planners as well as tradesmen customers have approached us with the desire for a system with a greater glass surface, a slimmer design and very good technical values, which can also be used for large static elements and in new buildings as well as renovations."
