Flat security doors: how to choose and how much they cost with installation
The entrance door to a flat protects your home from burglars, noise and cold from the shared corridor. When choosing flat security doors it is worth knowing a few technical parameters that separate quality doors from those that merely look the part.
Security class and certificate
Our security doors are certified in security class 3 (RC3). When you buy, you receive a certificate from the National Security Authority. The door cannot be forced open by human strength, and the all-steel construction cannot be cut by hand with metal shears.
Five things cheaper doors do not offer
- sound insulation of up to 40 dB,
- 10 locking points: 6 active bolts of the Italian ISEO lock and 4 fixed bolts against lifting out,
- ISEO R7 security cylinder in security class 4, resistant to drilling,
- steel leaf with a 1.25 mm shell and 50 mm mineral wool insulation,
- installation with the door frame set in concrete.
