Janisol C4

Fire Resistant Doors and Screens in Steel and Stainless Steel

The Janisol C4 range includes fire resistant doors and screens in either steel or stainless steel. These doors combine strength with very high fire protection features. They can achieve up to an EI90 fire resistance class with an installation depth of only 70mm.

Due to the 70mm installation depth, the Janisol C4 EI60 fire resistant doors and fixed lights have more than a 60-minute resistance, due to the intelligent fire retardant filling. This provides safety to your home or commercial areas.

The Janisol C4 EI90 thermally insulated steel profile used for elegant doors and glass walls achieve more than 90 minutes of resistance.

Fittings, locks and accessories can be integrated into the profile in an uncomplicated way. The appearance of these Janisol C4 doors is identical to the rest of the Jansen fire resistant systems.

These thermally insulated steel profiles are perfect for elegant doors and glass walls. These doors can be made into single doors, double doors or can be combined with fixed side panels, skylights or fixed glazing.
