Window protection shutters: types and features, how to choose

Window protection shutters consist of metal lamellas - horizontal segments with flexible bars, which descend from the holder as a roll. When you need to open the window, they raise. Protective roller shutters are fixed in a roll-up form above the window in a special box. Their purpose is to protect the home from intruders through the windows, isolate them from the impact of twigs or thrown rocks. Often protective shutters are installed on the windows in stores, offices. Installed also in apartments, if the owners rarely come to not worry about the safety of property.

Types of protective shutters

Protective roller shutters differ in the type of filling in the metal profiles:

• Hard or soft foam. Security shutters with this filling are suitable for apartments above the first floor. They are suitable for an office or store with a security system.
• Extruded aluminum. The lamellas of the roller shutters are 42 to 55 mm wide. Inside each segment there are reinforcing bars. Such protective shutters are installed on the windows on the first floors, in offices, stores.
• Lattice made of aluminum. An unusual variant of protective shutters. They are often used to protect shop windows and entrances to departments of shopping centers.

Security roller shutters may have additional properties, in addition to burglary protection. They come in sun protection, with noise insulation and protection against dust and wind. Models with foam in the segments slightly increase thermal insulation.

The locks on the security shutters are of two kinds. Most often used is the transom models of simple design, which are closed with a key. A more expensive variant is the electromechanical lock. It not only locks and locks the roller shutter, but also can stop the drive mechanism in case of burglary, and the leaf won't rise. Requires connection to electric mains.

Security shutters are differentiated by the type of control:

• Manual. Protective shutters weighing up to 12 kg are slid into the cassette with a cable, up to 20 kg - with a reducer cassette with a handle, from 10 to 60 kg - with an inertia spring.
• Electrically driven. Electrical power is supplied to the shaft in the cassette. System is actuated by a button fixed on a wall or by remote control.

If you have a lot of windows, as in offices and stores, then the electric control is the most convenient. It takes a lot of time to open every roller shutter manually. For market outlets, manual operation is suitable.
