Silica aerogels have been studied for long regarding applications for thermal superinsulation. Nowadays, some products are developed at industrial levels. However, some improvements are still to be achieved. Within this frame, first of all, we present in this paper some of the brand new advances in this sector based on literature examples (organic/inorganic hybrids and composites, nanodispersions, coatings, …). To illustrate our contribution to this sphere, we also detail some of our most illustrative realizations on superinsulating monolithic, granular and blanket-types materials, paying a particular attention to the famous “spring-back” effect based on silylation of the silica pore walls
