The invention belongs to the technical field of heat preservation and particularly relates to composite glass wool. The composite glass wool contains at least two glass fiber layers, and a nanoparticle layer is formed between every two adjacent glass fiber layers; the average particle diameter of nanoparticles is 0 to about 100nm; the nanoparticles contain nano SiO2; and the thickness of each nanoparticle layer is 50-1,000nm. Compared with the glass wool in the prior art, the composite glass wool has the advantage that on the premise of the same thickness, the heat preservation and heat insulation effects of heat preservation boards made from the composite glass wool provided by the invention can be remarkably improved.
