Glass partition walls physically separate spaces from each other, but at the same time enable visual contact. They are most popular in business premises, where employees should be separated, and are at least partially soundproofed. At the same time, the glass allows for some contact and a sense of closeness. Such walls do not close the space, as it nevertheless remains bright and open. When selecting and installing glass partitions, special attention should be paid to the sealing, as it needs to ensure durability and functionality over several years of use. With a prudent choice of appearance and colour combinations, we can ensure a high quality of living.
