A roof skylight set consists of a base, dome and (optionally) smoke vents or ventilation flaps.
the base is made of galvanised sheet 1,25÷5mm thick and 1000, 1250, 2500, 3000 mm long (standard lengths of sections);
standard height of the base: 300 mm or 500 mm;
the base is fitted with a lower shelf for the installation of the base on the roof structure;
section bases are joined together by means of screws;
the base is mounted to the foundation by means of tap bolts, screws or dowels, depending on what material the support construction is made of;
in case of larger skylight spans, bases are reinforced with bracings made from cold-bent sections; they are placed every 2500÷3000 mm.
