A polyol composition comprises a polyol, blowing agent, and a silicone polyether with an average chemical formula R3SiO(R2SiO)x(RRaSiO)ySiR3 where R is a C1-4 alkyl, x is 5-55, y is 1-10, x+y is 6-60, Ra has an average chemical formula —(CH)p-(EO)n(PO)m(EO)eH where EO is —CH2CH2O—, PO is —CH2CH(CH3)O—, e is 1-50, m is 2-10, n is 1-20, e+n is 25-70, p is one to 10, the PO content is >0 and <15 weight-percent of the weight of EO+PO, the EO content is >58 and <75 weight-percent of the silicon polyether weight, and the blowing agent is >70 volume-percent hydrocarbon blowing agent based on blowing agent volume and at least one of the following is true: (i) Ra has a number average molecular weight in a range of 1500 to 2500 grams per mole as determined by size exclusion chromatography; and (ii) the x+y is 50 or less.
