Venting Skylights

Mac Venting Skylights 

Mac Venting Skylights not only provide lighting but they also afford a means of ventilation. Even a small venting skylight will provide excellent ventilation due to the chimney effect created when warm air rises. Mac Venting Skylights are supplied with a hinged, two-piece, aluminum base frame, with thermal break in both Curb-Mounted and Self-Flashing models. Hinges are situated on the narrow side of the skylight and a hand-operated crank allows it to open a total of 11 1/2 inches (290mm). By simply releasing the lifting mechanism and removing the optional insect screen, the skylight can be manually opened completely for roof access or fire escape. Detachable 115 inch (2920mm) telescoping cranks, as well as motorized operators, remote controls, rain sensors, thermostatic controls, and insect screens are optional.
