Balcony window GDL 3066 Cabrio, GP2 PK19, Premium lower part

Roof window-balcony GDL 3066 Cabrio GP2 PK19 - lower part of the VELUX Premium series. Made of aluminum. It is mounted on the slope of the roof like any other roof window. When opened, it turns into a balcony.
The window consists of two elements. The upper part opens on the upper axis up to 45° through the lower handle, as well as on the middle axis through the upper handle for easy cleaning. The lower part is pushed forward, opening special railings on both sides.
The inner covering of the roof window-balcony is made of solid laminated pine wood with a water-based primer and two coats of azure varnish. In the name of energy efficiency, the model is equipped with triple /double/ laminated glass with special features. The outer glass is tempered with a thermal coating for better thermal insulation and a special additional coating for easier cleaning. The space between the panes is 16 mm and is filled with argon gas.
Made with modern materials with excellent insulation characteristics, the innovative system ThermoTechnology ™ turns the window into an extremely strong shield against wind and cold air. The result is less heat loss and a higher degree of energy efficiency.
The GDL Cabrio model has a built-in ventilation opening, which allows clean and fresh air to enter the room, while the filter does not allow insects or dust to enter the room. The ergonomic handle at the top of the window is used to control the ventilation opening.
The balcony window can be installed with a roof pitch of 35°-53°.
