proStratoTec is the new technology from KÖMMERLING and with its System 88 tilt and turn platform the company can now achieve the Passive House according to Dr. Feist Standard in full colour.
Thanks to its manufacturing process, the material Ultradur from BASF is integrated into the profile structure using a tri-extrusion process, making it possible to completely do without steel even with coloured and foiled profiles.
Historically System 88 has only been able to achieve the Dr. Feist Standard in white until now, which opens up endless possibilities for building specifiers with a certified Uf = 0.79 W/(m2K).
PVCu window profiles with the fibreglass-reinforced proStratoTec material are characterised by a particularly high degree of dimensional stability and rigidity. proStratoTec is extruded, similar to PVC, and if required also simultaneously with PVC.
The material can also be recycled without any problems, separated using colour sorters and later fed back into the production process as recycled material.
There are a number of advantages of proStratoTec, as it helps insulate much more effectively than steel and drastically improves a window’s heat transfer coefficient.
In addition, there is an enormous weight saving which pays off in production, transport and installation, especially with ever larger window elements.
There are also no other restrictions or changes in manufacturing and installation processes and proStratoTec products can be processed on any production line without any special conversion.
Robert Thiroff, Managing Director of profine UK and the KÖMMERLING brand commented: “Our System 88 platform is a flagship product from a technical perspective and this latest development of proStratoTec opens up considerable opportunities in colour whilst meeting the important Dr. Feist Standard. Innovation, research and product is very much part of the KÖMMERLING DNA as is our commitment to a better world for all.”
