Forbo Marmoleum Click Cinch Loc Seal is 0.39 inches (9.88 mm) thick. For most installations, we recommend QuietWalk Plus padded underlayment, which is 0.13 inches (3.18 mm) thick, bringing the combined thickness to about half an inch. Other options, such as Moisture Block or Quiet Board, may be suitable depending on your installation needs. Check the product instructions to ensure your underlayment is compatible with Forbo marmoleum flooring.
