Dormer Apex
System
The Keylite Dormer System opens up the opportunity for a unique fresh air experience with the convenience of the top handle on our Centre Pivot Windows, allowing easy opening to create a well ventilated and bright space.
Available in a configuration of 4 or 6 windows, the Keylite Dormer can be made even more practical with the selection of Electric or Solar powered options for maximum fingertip control.
