TAMKO Building Products has a solar attic vent that runs entirely on the energy the vent collects from the sun. These solar-powered vents are made from durable materials including tempered glass and UV-stabilized ABS color-dyed plastic. The solar attic vent has an optional cold-weather thermostat that automatically disengages the fan when the temperature falls below 50 degrees Fahrenheit. The vent also has four different mounting options, including an option that allows the solar panel and the vent to be installed in separate locations. For more information, visit www.tamko.com.
