Flooring underlayment we keep physically in stock on Oahu — no waiting on mainland freight. This collection covers our most-requested acoustic and cushioning underlayments for vinyl plank, laminate, and hardwood, including options that meet Honolulu condo HOA sound requirements (IIC ratings). Bring your building's specs and we'll match you to a compliant underlayment with printed sound test reports for your board submission.

Pick up same or next business day from our Waipio warehouse, or we ship to all Hawaiian islands via Young Brothers. Not sure which thickness you need? See our HOA underlayment guide or call (808) 210-4807.
