GDL MK19 Balcony Roof Window with Laminated LowE3 Glass

Rough Opening Dimensions: 33-1/16 in. x 101 in.

The GDL MK19 Balcony Roof Window brings a sophisticated touch to your home, offering both aesthetic appeal and practical functionality. With its dual-sash operation, the upper sash opens upward while the bottom sash unfolds to form a balcony, complete with side railings, creating a seamless connection between your indoor and outdoor spaces. Ideal for upper-floor rooms with sloped ceilings, it provides abundant natural light and enhanced ventilation, making it perfect for bonus rooms, attics, and lofts.

Constructed with durable Laminated LowE3 glass, the GDL MK19 window offers excellent energy efficiency and protection against harsh weather, including a 10-year hail warranty. The interior frame features a clear-lacquered finish, maintaining a clean, natural wood look that complements modern and traditional interiors. The weatherproof flashing kits (EDL MK19 for shingle, shake, or slate roofs and EDW MK19 for tile roofs) ensure a secure, weathertight installation. This window is designed for roof pitches between 35° and 53°.
