With the UMBRA expansion profile, the wall gap can be adjusted from 0 to 100 mm. This requires an additional structural profile, which is mounted onto the expander at the desired distance. The resulting structure is then installed into the base profile. A second use case for the expander is to create a niche anywhere in the ceiling using two UMBRA structural profiles, with the option to add lighting. With the UMBRA system, there is no need to mill the drywall. This is one of the key features of its efficient installation — faster, simpler, and without requiring extra tools.
