The JOCZ Firesave product line is used for manufacturing internal single- and double-leaf fire doors with fire resistance classes EI 15, EI 30, EI 45, EI 60, or EI 90, according to the PN-EN 13501-2:2016 standard. This system also enables the construction of so-called technical windows and fire-resistant partition walls.
The solution is based on aluminium profiles with a thermal break from the MB-60E EI and MB-78EI systems, where the structural depth of the sections is 60 mm and 78 mm respectively. The fire resistance of the structure is ensured by fire insulation elements mounted in the internal chambers of the profiles. Additionally, the structures are equipped with intumescent strips, which form an impassable barrier in the event of a fire.
The doors can additionally meet the requirements for smoke tightness in class S200, Sa according to PN-EN 13501-2+A1, and self-closing capability in class C5.
Infills can consist of all typical fire-resistant glass panes, as well as layered opaque elements composed of sheet metal and suitable boards providing the required fire protection. Within this system, smoke-proof constructions can also be achieved.
