1. A method for manufacturing an aerogel blanket, the method comprising:
(Step 1) introducing a catalyzed sol and a substrate for the blanket into a reaction vessel, and
(Step 2) performing gelation while rotating the reaction vessel,
wherein the substrate for the blanket is a porous substrate, and
wherein the catalyzed sol is introduced in an amount of 80-120% based on the volume of the substrate for the blanket.
