Abstract
The transparent fire-resistant glazing has at least two glass or glass ceramic panes with a gap between them, which is filed with a UV-cured material made by curing a UV-curable material with UV radiation. The UV-curable material includes at least one bromine-containing flame retardant, which is a polybrominated diphenyl ether, a brominated alcohol, or a polybrominated cycloalkane, and/or a mixtures thereof. The glazing is made by a process in which the panes are cleaned and masked so that there is a gap between them, the UV-curable material is filled into the gap and then cured with UV radiation.
