Second Underlayment for Coretec Pro LVP?

What material do you recommend for a second underlayment under Coretec Pro lvp? These are going in a basement over a concrete subfloor in the Pacific Northwest. House is 80 years old, and knock wood, water has never been an issue. Insulation from the concrete is a consideration. The Coretec has a thin cork underlayment attached.
I've talked to the manufacturer and extensively researched different options, but hoping to get some firsthand feedback on plastic sheeting vs. cork as a second underlayment. Open to recommendations on specific products.
