CurveTech skylights are designed for use on flat or low-pitch roofs with pitches from 0 to 15 degrees. The curved edge-to-edge glass cover allows rainwater to disperse off the glass while installed on a zero-degree roof pitch, according to the company. The skylights come with a PVC curb with polystyrene filling and can be topped with a glass or polycarbonate dome. Available models include the fixed flat roof skylight or the flat roof exit skylight, which is available for polycarbonate dome covers and can open to a 60-degree angle.
