Innovative melamine interior doors with a wide range of colors, ornaments, glazing and fittings. The ISY and ISY Plus models are Dierre’s new series of interior doors focused on trends in modern interior design. New solid wood frame in variants, opening outwards and inwards. The idea is for the sash and frame to be in the same plane regardless of the opening direction, and thanks to the hidden hinges, the vision of two adjacent doors with different opening directions remains the same.
