On January 13-14, 2016, a large-scale test of fire resistance of selected parts of wooden construction was conducted under the guidance of prof. Ing. Juraj Olbřímek, PhD. and Ing. Soňa Leitnerová from Slovak Technical University in Bratislava (Slovakia). The test was carried out in the experimental laboratories of the FIRES: The Experts on Fire Safety company in Batizovce (Slovakia). The experiment focused on the fire resistance of wall-ceiling contact and the impact of fire barriers on the fire spread in wooden construction cavities. Experts in the field of fire safety from several leading Slovak institutions and foreign guests from the Czech Republic and Sweden participated in the fire test as well. Two members of the Institute of Informatics, J. Glasa and P. Weisenpacher were invited to participate at the event.
