DetailsEternity SG is a premium underlayment for floating hardwood and laminate floors. For quiet floors, nothing is better - IIC73/STX72 and Delta IIC21 acoustical ratings are the industry's highest (far exceeds building codes). Works well over radiant heated floors. With patented Seal Guard, the attached lip and tape system seals seams to create a building code approved vapor barrier.
