MP Global Underlayment - QuietWalk Max 100sft, $94.99 USD/Box, LL Flooring (Lumber Liquidators)

QuietWalk Max utilizes a unique silver film that reflects heat to enhance home comfort. It acts as a protective barrier against moisture and high pH levels from concrete subfloors. The dense, antimicrobial fiber pad, combined with its vapor barrier, forms an effective water management system that wicks away moisture while preventing high pH exposure. It smooths minor sub-floor imperfections, adds insulation value, and is compatible with in-floor heating systems. Constructed from recycled materials, it enhances performance for flooring with attached pads and is made in the USA.
