2.2	GENERAL CHARACTERISTICS FOR SKYLIGHTS AND ROOF WINDOWS
A.	General Characteristics:
1.	Finished wooden frame; pressure-treated, double coated with water-based clear acrylic lacquer.
2.	Energy Star, Low-E, UV filtering glass; laminated or tempered glazing.
3.	Single or double chamber filled with thermal-regulating inert argon gas.
4.	Perimeter seal and sturdy wooden frame for "warm" roof boarding-skylight frame joint.
5.	Bracket-free, one-person installation (skylights only).
6.	Type EL step or EH-A high profile flashing required.
7.	Template and installation hardware included.
B.	Leaks and Condensation:
1.	Deck Mounted Skylights: Lined on underside with a gasket. When skylight is placed in rough opening, this gasket creates a seal against the roof deck. Water and ice shields waterproof the skylight, making it impermeable to moisture.
2.	Skylights are installed without the use of metal components. Provided screws drill directly through the frame of the skylights into the roof joists eliminating the need for brackets on the outside of the skylight's frame.
3.	On the inside of the home, a channel built into the inner frame of the skylight collects moisture and drains it to the outside. This channel is set deep into the frame of the skylight where the glass meets the skylight's frame, so the channel is not visible once the skylight is installed.
