Velux has an updated Sun Tunnel Model
Velux has improved their Sun Tunnel product. It is easier to install, has a factory sealed double glazed ceiling lens and has an adjustable flashing kit for pitched roofs. Velux continues to improve all of their products over time and we are excited to see these latest improvements. As far as I know there is not another solar tube or tube lite manufacturer that has the dual glazing that helps prevent heat loss from the home.
