Shaw's Pet Perfect Underlayment is a premium LVT and mineral core underlayment featuring sound suppression and moisture barrier. Smooths uneven subfloors to save installers time and money with no messy prep work 

Fanfold panels lay flat, and easy-to-cut grid lines make installation simple. They guard against mold and mildew beneath the subfloor. Shock-absorbing technology supports floor locking systems and increases comfort.

Thermal insulation is a great product for basements, making floors feel warmer. The product is radiant heat approved. However, subfloor temperature cannot exceed 85° for radiant heat installation.
