The present invention relates to a substrate (1) coated with a porous layer (2), to the processes for manufacturing the layer and to its applications. The porous layer (2) is mainly inorganic and of sol-gel type having a series of closed pores with at least the smallest characteristic dimension which is, on average, greater than or equal to 20 nm and less than or equal to 100 nm.
