Roof skylights are used as natural upper lightning. They are intended for incorporation into flat or slightly slanting roofs in order to provide natural lightning and, potentially, ventilation for rooms located below or in order to obtain easier access to the roof. The whole range of Blue Sky skylights offered has been designed from modern materials so that they can be assembled extremely easily and used for many years as well as so that they are completely waterproof and windproof as well as highly aesthetic. Roof and dome skylights are our speciality!!
