In sliding, they cannot provide the desired performance at high pressures due to both insulation problems and water discharge problems, recently sliding groups are wanted to be used in high-rise buildings and towers for comfort reasons, but due to the reasons I mentioned at the beginning, standard sliding systems are not sufficient, therefore, with the push-slide or pull-slide mechanisms developed by the Roto-Frank accessory company, it prevents air and water leaks at high pressures by continuously and continuously compressing the seals in the wing frame all around, 1800 Pa water impermeability performance continuity is provided with the opportunities provided by the mechanism and the water discharge channels made in the system. In my system designs, in addition to performance, I constantly think about functionality, user convenience and aesthetics together, make dozens of detail solutions until the final details are revealed, and try not to overlook the smallest detail, success is no coincidence.
