Roberts 70-025 Unison Underlayment

Roberts Unison 2-in-1 Underlayment for Laminate and Engineered Wood Flooring is designed with a 3/32 inch polyethylene foam for cushioning and a 2 mil. thick top film to protect from harmful moisture vapor. This product is designed to use for wood subfloors but can also be used with concrete slabs with recommended MoistureBarricade (Item# 70-115, sold separately). Unison’s foam construction also reduces everyday surface noise. The adhesive strip and overlap make it easy to join rolls during installation.
