The polyol composition includes 50% to 80% by weight, based on total weight of the polyol composition, of an aromatic polyester polyol having a functionality of 1.5 to 2.5 and an OH number of 150 to 360 mg KOH/g, and an amine-initiated polyether polyol having an OH number of more than 500 mg KOH/g and a functionality of 2.5 to 4. The blowing agent composition includes a hydrofluoroolefin and water. The catalyst composition includes a morpholine, an imidazole, a quaternary ammonium carboxylate, and a metal carboxylate.
