How do VELUX skylights prevent condensation from forming?

Our skylights are designed with several layers of protection that fight against condensation. They open: releasing warm, moist air. Insulated: the wood sash and frame used in the skylight is an excellent natural insulator unlike metal or vinyl. Energy efficient glass: VELUX skylights are available with Low-E insulated glass. Low-E keeps the interior glass pane warmer, lessening the chance of condensation forming. Gasket system: should condensation occur, VELUX skylights are equipped with exclusive gasket system that drains condensation from the outside.
