In this work we have studied a new type of monolithic silica aerogels (xerogels) made without supercritical drying. The xerogels are produced by performing washing and ageing treatments on the alcogel before drying at ambient pressure. Densities as low as 0.26 g/cm 3 have so far been obtained and th
