Skylights must be installed on roofs with slopes between 0 degrees (0:12) and 75 degrees (45:12) from the horizontal. A mininum height of 4 inches (102 mm) between the plastic glazing and plane of the roof must be maintained. In the event of conflict between this report and the manufacturer s published installation instructions, this report governs Self-Flashing: The self-flashing skylights are mounted directly to the roof deck assembly. Compatible sealant must be applied on the mounting flange of the selfflashing unit and covered with the roof covering in such a manner as to ensure a watertight seal. See Figures 1A and 1B for more installation details Curb-Mounted: The curb-mounted skylights must be installed on a wood curb made of minimum 2-by lumber with a minimum 0.42 specific gravity. The wood curb and the attachment to the roof structure must be designed to resist the appropriate code-prescribed loads. The gap between the skylight frame and the wood curb must be fully shimmed. Flashing must comply with, and be installed in accordance with, IBC Section 1507 or IRC Section 905, as applicable. See Figures 1A and 1B for more installation details. 4.2 Installation of Skylights noted under Table 2: General: The skylights must be installed in accordance with IBC Sections 2405 and 2610, or IRC Section R308.6, as applicable; this report; and the manufacturer s published installation instructions. Skylights must be installed on roofs with slopes between 14 degrees (3:12) and 75 degrees (45:12) from the horizontal. A mininum height of 4 inches (102 mm) between the plastic glazing and plane of the roof must be maintained. All EZ skylights are limited to where nonclassified roof coverings are permitted except when the fire-resistant ring and spun self-flashing curbs are installed. In the event of a conflict between this report and the manufacturer s published installation instructions, this report governs. The skylights are prepackaged with all components, fasteners, attachments, and installation instructions in the shipping carton, except for the sealant recommended by the skylight manufacturer to be installed between the skylight and roof sheathing. For the EZ10, a 12-inchdiameter (305 mm) hole must be cut in the roof sheathing and an 11-inch-diameter (279 mm) hole must be cut in the ceiling below the attic space. For the EZ14, the corresponding ceiling and sheathing hole diameters are 16 inches and 15 inches (406 mm and 381 mm), respectively Self-Flashing: The skylight self-flashing curb must be treated with the sealant recommended by the skylight manufacturer applied around the bottom surface of the flashing and then must be attached to the plywood or OSB roof sheathing with the fasteners described in Section The number of fasteners required is given in Table 2. The skylight dome lens must be attached to the selfflashing curb with four of the fasteners described in Section Silicone sealant must be applied to the screw heads after placement. The reflective tubes must be inserted into the skylight self-flashing curb at the roof and must be terminated at the ceiling into a ceiling ring installed with three or four No. 6 by 1-inch-long (25-mm) drywall screws. The skylight diffuser must then be twisted onto the ceiling ring.
