The benefits of natural illumination of the building are unquestionable but it happens that in buildings with flat roofs it is not always possible to install standard vertical windows. Ideal solution in such cases is installation of specially designed products for flat roofs.

Various control accessories such as a wall switch and opening rods are also available for the electrically (DEF) and manually (DMF) operated skylights.
