New Aluminium Fire-Rated and Smoke-Proof Doors.

We are proud to introduce a new line of aluminium fire-rated doors that have successfully passed fire resistance and insulation tests at the accredited Fire Research Laboratory of the Building Research Institute ITB.

Fire tests of aluminium doors

were carried out in accordance with EN 1634-1:2014-03+Ap1:2016-10P standard in a special furnace in a wall made of 180 mm aerated concrete blocks with a reinforced lintel. Preparation of the fire test took several months: Sample fabrication under laboratory supervision took several weeks, the reinforced concrete lintel was prepared 3 months before the test, the wall structure was made a week before the test, and the door sample was installed on the eve of the tests. The door sample was embedded in the test wall using steel anchors at an appropriate spacing, the space between the wall and the door frame was sealed with mineral wool of appropriate density and covered with a cement plaster. This method of installation does not differ from the standard installation of fire doors.

The process of testing aluminum fire doors.

During the test, the fire resistance and insulation of the door were tested, the temperature on their external - unheated - surface was measured using several dozen thermocouples suitably arranged and connected to the measuring equipment. According to the research standard, the fire tightness criteria are the resistance of the structure to leakage and penetration of flames to the external - protected side in the measured time. The fire insulation criterion is the limitation of heat flow from the heated side of the structure to the external - unheated side in the measured time. During the tests, the loss of fire tightness is confirmed by the appearance of flames on the external side, ignition of a special tampon and application of appropriate gap gauges. The loss of fire insulation is defined as an above-standard temperature increase on the external side and confirmed by means of thermocouples attached to the external surface of the tested door.

The sample of doors for fire tests was made of aluminium profiles with a thermal break and fireproof inserts. The doors were equipped with an emergency lock with fire classification and drop seals in the lower edges of the doors. The new range of products includes single- and double-leaf fire-rated and smokeproof aluminium doors in classes Sa and S200 according to EN 13501-2+A1:2016, used as emergency exits.
