Design Door Altair

Bertolotto's "Costellazioni" designer door collection was inspired by the International Astronomy Year. Every door is unique and finely decorated. The geometrical decorations on door leaves reproduce the essential lines of constellations.

The door structure is sturdy, strong and solid, whilst decorations are light and details are carefully refined. You can choose between mat and polyester glossy finish, with a perfect mirror effect. Besides its elegant models, the Costellazioni collection also includes glass doors, with transparent or satin tempered safety glass.

The flush-mounted door is an elegant architectural solution that harmoniously blends functionality and aesthetics. This door appears to disappear within the wall, creating a clean and minimalist look.

The distinctive feature of the flush-mounted door is the absence of visible frames and protrusions, thanks to its ingenious recessed system. This design allows for a seamless transition between spaces, eliminating visual obstacles and optimizing available space.

This door is ideal for lovers of contemporary design who desire a clean and discreet appearance for their interiors.
