Choosing from many firms, my choice fell on the Neman. I explain why: a wide assortment, courtesy of the staff, many variations of the door configuration, thermal insulation, anti-noise, and most importantly, what distinguishes the Neman from its competitors is protection against a killer knife.
As with any door, burglar resistance is the number one priority, and looking at the Neman site, I saw a wide range of different locks, armor plates, and armor plates, which could not but rejoice.
According to the manager’s advice, he took a model of N-110 with protection against a knife-knife at a discount, the craftsmen measured and quickly installed.
And now for 8 months the door has been standing like new, absolutely without complaints or side effects.
