Southeastern Insulated Glass, Inc. (SIG Skylights) has been operating in Atlanta, GA since 1975. We are conveniently located near the intersection of I-285 and I-85. We specialize in manufacturing custom skylights of all sizes and shapes. Our skylights are extremely durable, beautiful, and a smart investment! They are backed by a lifetime warranty on the frame. They are made with tempered, insulated glass that resists scratching and does not fade or craze like plastic skylights. The opening in each skylight exactly matches the hole - thus maximizing daylight into the home. Our prices are competitive. The insulated glass units are available in a variety of colors and coatings which conserve energy and reduce glare, overheating, and UV damage. SIG deck mount skylights are extremely simple to install. Because of the wide, 4.5" flange, they are self-flashing, i.e. they do not require an expensive, complicated flashing kit to install. Simply remove some shingles, cut the hole, seal the skylight on the top and bottom with sealant or self sealing roofing membrane, screw the skylight down, and replace the shingles.
