AT

The wider and more versatile range of Dierre security doors.

The main lock is controlled by a double bit key, while the "Mia" block allows unlimited substitutions of the key without changing the entire lock.
If properly fitted, AT provides a noise reduction of 38 dB according to UNI EN 140, and air tightness in class A2 according to EN 86.

Note: The noise reduction values are measured in the laboratory according to the above mentioned standards. The values measured during onsite installation may not reach similar values as a result of inferior performance or imperfections of the civil engineering works and installation.

Available in the single or double leaf versions.
The closure system is also available in the class 4 version.
