Maximum security, variety and elegance

SAELZER security aluminium windows of the series S2es and S6es offer individual design options and provide combined security against forced entry, ballistic and blast attacks and against pressure waves.

The windows of the two series differ in the level of protection against forced entry and ballistic attacks:

  • Series S6es: Forced entry resistance up to class RC4 | Bullet resistance up to class FB4-NS.
  • Series S2es: Forced entry resistance up to class RC5 | Bullet resistance up to class FB7-NS.
  • Both series offer the same high protection against blast attacks, up to a pressure load of 880kPa (8.8 bar)

The following test video shows a forced entry test of the window series S2es, resistance class RC5. Use of massive tools such electric power drill or axe:

Aluminium windows of SYSTEM SAELZER® permits various design options for individual requirements: whether exact replica of historical elements, windows for robust use in industrial or military property, the elegant design for embassies as well as a comfortable style for a private residence (design variants table below).

Series S6es:
Class 2:
Tilt hardware: 20.000 open-close cycle
Turn hardware: 10.000 open-close cycle

Sizes | glazing | hardware | design
Profile depth Depending on the security level. Frame: 135 mm
Wing: 145 mm
Frame : 115 mm
Wing: 125 mm
Glazing Security class of the glazing is the same resistance level as the complex construction. Fixed light: 97 mm
Openable window:
102 mm
Glass thickness up to 90 mm with flush glazing beads.
Profile widths Despite high security components small profile widths e.g. sash profile with of the series S6es up to 35 mm (inside dimensions).
Glazing bead There is no visible screwing of the glazing bead required due to the stable design. Also no glueing necessary (natural glazing rebate ventilation and water circuit). Glazing beads are anchored pressure and impact resistant in the slot of the profiles.
Height Minimum and maximum wing dimensions, depending on the desired level of security.
Design Single and multiple window elements, available with turn, tilt or tilt-turn window hardware, sliding element, french casement window (series S6es), continuous window, with top and side lights, or as round-arched window.
Surface Anodized or powder coated. Planked with all kinds of stainless steel, stone, bronze, various types of wood.
Hardware | wing weights  Hardware for heavy weights. Weights: turn hardware up to 300 kg, tilt hardware and tilt-turn hardware up to 200 kg.
Installation Installation in several building materials permitted. Bullet resistance: a bullet resistant wall connection is tested and recommended.
