A process for producing rigid polyurethane foams by reacting a) organic polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, in the presence of c) blowing agents, d) catalysts and, if appropriate, e) auxiliaries and additives, wherein a mixture of b1) from 20 to 60 parts by weight of one or more high-functionality polyether alcohols having functionalities of 3.5-5.5 and a hydroxyl number of 400-550 mg KOH/g, b2) 1-20 parts by weight of one or more polyether alcohols based on aliphatic amines and having functionalities of 3.5-4.5 and a hydroxyl number of 450-900 mg KOH/g, b3) 10-30 parts by weight of one or more polyether alcohols and/or aromatic polyester alcohols having functionalities of 1.5-3 and a hydroxyl number of 150-450 mg KOH/g, and b4) optionally 1-5 parts by weight of water is used as polyol component b). The polyol component b) has good storage stability and the rigid polyurethane foams obtained have good surface quality, a good degree of curing and adhesiveness.
