(57) Abstract: The current disclosure provides reinforced aerogel compositions that are durable and easy to handle, have favorable 
performance in aqueous environments, have favorable insulation properties, and have favorable, reaction to fire, combustion and flame
resistance properties. Also provided are methods of preparing or manufacturing such reinforced aerogel compositions. In certain em
bodiments, the composition has a silica-based aerogel framework, reinforced with an open-cell macroporous framework, and includes 
one or more fire-class additives, where the silica-based aerogel framework comprises at least one hydrophobic bound silicon and the 
composition or each of its components has desired properties.
