IPO/A double-leaf balcony door

Inward-outward opening balcony double doors, are more soundproof than a single leaf balcony door. The exterior door leaf is aluminium and has the same standard colors than windows.

Standard aluminium colors are:

RAL 9010 (white)
RAL 7040 (light grey)
RAL 7024 (dark grey)
 RR 32 (dark brown)

Representation of the colors on the screen may differ from painted samples. Please always check the chosen shade from a printed color chart or a painted sample.

The interior leaf is wooden, which can be painted, lacquered, protective coated or stained to desired shade. The glass in double-leaf balcony doors can be manufactured to the desired height, as with single-leaf balcony doors.
