Why Tile Underlayment from Prolux Materials Is Worth Every Layer

Peace of Mind Under Every Tile – Quality tile underlayments create a stable, durable foundation that helps reduce failures and extend the life of your floor.
Helps Protect Against Cracks and Shifting – A tile underlayment membrane absorbs movement and subfloor stress, reducing the chance of cracked grout, lifted tile, or delamination over time.
Creates a Flat, Even Surface – Underlayment systems support a smoother base, improving adhesion and finish quality across the entire floor.
Labor-Saving Installation – Many membranes are lightweight and easy to cut, helping reduce installation time for DIYers and professionals.
Moisture Management Built In – Underlayment layers can provide a protective barrier that resists moisture while allowing vapor to dissipate, reducing the risk of mold and mildew in the assembly.
