EI class fire resistant swing door
The EI glass swing doors came from the need of providing a passive protection system against the spread of fire and allowing better evacuation of personnel in case of a fire. The EI-classified glass is made up of a metal frame with a thermal bridge. Its insulating elements and swelling of the strips seal the holes preventing any passage of flames in the case of significant increase in temperature. The glass used, completely clear and transparent, correspond to classifications ranging from EW30 to EI120. Single-slide opening of 1 swing leaf and/or bi-part opening with 2 swing leaves. Metallic EI glass swing doors have been tested and certified by approved laboratories according to current regulations. The technical and compositional characteristics vary depending on specific requirements, with metallic structures such as aluminium or stainless-steel plates available.
Different finishing options are available. Lacquered is available for the metallic profiles or anodized and lacquered is available for the aluminium option. For the stainless option AISI304 and 316 is available.

Frequently asked questions about EI class fire resistant swing doors
Manusa fire-resistant automatic swing doors operate in the same way as our standard doors except if there is a power cut due to a fire, an alarm or similar. In the event of a fire, when the flames come into direct contact with the wall, the intumescent materials start working and seal the door within 4 or 5 minutes, preventing the fire from spreading and ensuring the door does not open.
In the case of a fire, the doors must remain closed but not locked, that is, the leaves should be closed in order to stop the passage of flames, smoke, gases and high temperatures between areas when the fire reaches them.
