Venting Dome

Our Venting Dome design not only provides lighting but also affords a means of ventilation as the skylight can open. Even a small venting skylight will provide excellent ventilation due to the chimney effect created when warm air rises. Our Mac Venting Skylights are supplied with a hinged, two-piece, aluminum base frame, with a 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. Additional features include detachable 115 inch (2920mm) telescoping cranks, as well as motorized operators, remote controls, rain sensors, thermostatic controls, and insect screens.
