KELLER minimal windows®4+
The Keller minimal windows® 4+ sliding window system.
Low energy standard and slender design as a unit
Modern architecture is characterised by clear lines and large window areas that flood rooms with light. Since 2007 KELLER AG has been supporting architects and building owners all over the world in creating modern, bright living space in their projects with its KELLER minimal windows® system. With the KELLER minimal windows® system it is possible to realise large-area fixed and sliding windows in glass and thus to achieve maximum transparency. With their puristic reduction, the profile frames retire completely into the background. Significantly improved design standards are becoming accepted due to increased environmental awareness and the striving to implement highly efficient energy applications. This high standard of energy-saving glazing and maximum energy efficiency is met by the new Keller minimal windows®4+ series. The KELLER minimal windows®4+ system offers outstanding thermal insulation with Uw values of less than 0.80 W/m²K and meets the latest low-energy standards thanks to triple glazing. Sliding leaf areas of up to 12 m² can be realised, and with maximum ease of use at that.
KELLER minimal windows® have in the meantime made a name for themselves beyond Europe. The new sliding window system won the Innovation Award at the international building trade show ‘BAU 2009’ in Munich and was also among the laureates of the Luxembourgian Innovation Award 2010. These successes are indicative of how well the system has been received by the trade and of the outstanding quality of the large-area window elements. Architects, glass manufacturers and specialist companies place their trust in the high quality standards of KELLER minimal windows®. Constant further development contributes to the fact that large glass surfaces with leaf weights of up to 1000 kg can be used. This is made possible in particular by the specially developed roller carriage technology, while retaining the slender profile design. Glass thicknesses of up to 56 mm can be used without problem.
With the innovative KELLER minimal windows® sliding window system, the KELLER company is pursuing the ambitious goal of offering the market the best solutions, in terms of both execution and design, and of convincing with outstanding system characteristics.
