The frameless balcony window and window originated from the cold Nordic countries. At present, our company has projects in Russia, so the frameless window is completely suitable for the northeast region. The balcony is a landscape place where the family is casual, windy and wind-covered, and there is no vertical gear between the glass, which can be fully opened. The convenience of scrubbing is the biggest advantage of the frameless window, so the frameless balcony window is in the south or the north. The city is the best choice for balcony packaging.
