Retrofitting security concept
Secondary windows can provide additional levels of protection against forced entry, ballistic attack and blast without need to exchange regular windows. By installing secondary windows the outward appearance of the building is maintained whilst at the same time upgrading the level of security to any perceived threat, thus offering protection to the occupants and contents. Even windows for buildings under preservation order can be designed according to this design requirements. Therefore, this security concept is also an ideal solution for time-limited use.
Choose from the extensive, tested and certified SÄLZER product portfolio to create a secondary window system: aluminium façade S1es, aluminium window S2es-w, aluminium window S6es-w, SECUFIRE® steel series.
External or internal installation
The secondary glazing system can be alternatively installed outside at the wall or inside.
