Roof Window Balcony Replacement (VELUX GDL)
Transform Your Loft into a Balcony — Open the Roof and Step Outside
The VELUX GDL Roof Balcony Window opens your roof to the outdoors.
When opened, the upper section lifts outward while the lower section unfolds to create a small standing balcony, giving you fresh air and an unobstructed view.
The interior frame is made of natural pine wood with a clear lacquer finish — warm, elegant, and ideal for dry living areas such as bedrooms and lofts.
The GDL provides maximum daylight, excellent insulation, and transforms any attic into a bright, inviting living space.
