The round dome rooflight for optimum energy efficiency
In addition to the square version, our tried and tested energy efficiency classic is also available as a round version with the 4-skinned TOP-90 comfort. It is ideally suited to both new constructions as well as refurbishments. In addition, its outstanding thermal insulation properties and excellent light transmission are particularly impressive.
The round TOP-90 comfort has a variety of applications. Depending on the additional accessories, this dome rooflight can be utilised with sun protection, fall-through protection or – with the corresponding opener drive units – as a ventilation system and/or SHEV system (LBO). In addition to this high level of functionality, it also impresses with its modern and aesthetic design.
