I thought a lot (mostly because of the differences in insulation solutions) about whether to choose a lift-and-slide (from another manufacturer) or a regular sliding balcony door. One of the best decisions during the construction was choosing them and the regular sliding Roto hardware. Operating the large sliding doors is much simpler and more convenient, and the insulation is also perfect.
I was particularly satisfied with the installation; they did a very precise and accurate job, and I didn't have to intervene in anything. Thank you. ;)
