The round dome rooflight for optimum energy efficiency
Our tried and tested energy efficiency classic is not only available in square, but also as a round version with the 4-skinned TOP-90 comfort. It is ideally suited for both new construction as well as refurbishment. Its outstanding thermal insulation values and excellent light transmission are hereby particularly impressive.
The round TOP-90 comfort is versatile in use. Depending on which accessories you supplement it with, this dome rooflight can be utilised with sun protection, fall-through protection or – including 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.
