How do VELUX skylights prevent condensation from forming?

1 min. readlast update: 12.10.2025

VELUX skylights are designed with several layers of protection that prevent condensation:  

  • They have the ability to open to release warm, moist air.
  • The wood sash and frame used in VELUX skylights is an excellent natural insulator, unlike metal or vinyl.  
  • VELUX skylights are available with Low-E insulated glass. Low-E keeps the interior glass pane warmer, lessening the chance of condensation forming.  
  • Should condensation occur, VELUX skylights are equipped with an exclusive gasket system that drains condensation that forms on the outside glass.
