<p>The present invention refers to a fire resisting or retarding sheet unit (1) intended to be provided in/at e.g. an insulating glass, windows, a door, a facade, in order to improve their fire retarding qualities during a fire. Said sheet unit (1) comprises at least two hardened glass sheets (2) between which at or near an edge area (6) of said sheet unit (1) at least one spacer element (3) is provided in achieving of a distance (4) between the hardened glass sheets (2), said glass sheets (2) are cooperating in a fire technical way to withstand fire and that at least one space (7) is created between the hardened glass sheets (2) containing at least one gas (5) such as air, inert gas, argon, so that the fire retarding sheet unit (1) can resist fire during a certain of time in order to reach a predetermined fire requirement.</p> |
