Forced entry and bullet resistance

Louvers or weather-protective grilles are used everywhere, where rooms must be vented and also protected against forced entry and bullets.
The louvers provide natural ventilation and protect rooms or buildings against unauthorized entry through the ventilation shaft.
Through the special placement of the single blades, SAELZER louvers offer resistance against bullets and protection against rain and wind.

SAELZER louvers are tested and certified according to European and American standards:

  • According to the European standard: forced entry resistance level  RC5 in combination with bullet resistance FB6-NS.
  • According to the standard of the US-Dep. of State: 5 min FE and 60 min FE/BR

The solid and very robust louvers are manufactured of steel. The louvers, which are tested to the European standard are also available in stainless steel.

The blades are available in horizontal or vertical position. By combination several louvers, larger areas can be secured and ventilated. Optionally a shield against insects can be added on the inside.
