A light transmitting panel composed of at least two panes held in spaced relation by a spacer assembly to define at least one space between panes is given improved sound damping properties by giving such space a thickness of greater than 9mm, by causing the space between panes to be sealed from the external atmosphere, and by filling this space with a gaseous medium composed of air and at least one other gas, the air constituting at least 30%, by volume, of the medium, and whose composition is such that the velocity of sound propagation therethrough diff...
In a light transmitting panel composed of at least two panes, and spacer means holding the panes in spaced relation to define at least one inter-pane space therebetween, the improvement wherein, for improving the sound damping properties of said panel, said inter-pane space is more than 9mm thick and is sealed from the atmosphere, and said panel further comprises a gaseous medium at least 30% by volume of which has the composition of air, the medium further including a quantity of at least one other gas, and the composition of said medium being such that...
