With Sleek, Dierre makes the movement of the armored door free, allowing full openings up to 180 degrees even on a large leaf and creating a double closure system which improves protection against noises and weather at all seasons.
With a further plus: the flush installation that hides the frame, allowing to raise the door or integrating it completely into the wall finishing.
All this can be possible thanks to the new Macron 5.0 hidden hinge, patented by Dierre, inspired by the aeronautical field.
A solution that matches design and functionality with a thermal insulation up to 1.2 W / m2K, acoustic rating up to 45 dB and
burglary resistance to Class 4.
