Comprehensive technical information

Ease of installation is decisive

With their QuinLine® lift and slide door, SCHMIDT offers you a particularly easy-to-install product. The profile system is not only lighter than other systems, which is important for easy transportation on the construction site, but is also very forgiving.

Since the installation of lift and slide doors is different from that of windows, SCHMIDT offers comprehensive information material as well as training for fitters.

Because if you know what to look out for, handling on the construction site becomes much easier. For window manufacturers, this means a significant minimisation of time and costs.
