Tile Underlayment That Lays the Groundwork for a Flawless Floor

When it comes to tile, a beautiful finish starts beneath the surface. That’s where tile underlayment from ProLux Materials makes all the difference. Designed to create a strong, stable base, our underlayments help prevent cracks, reduce movement, and protect your tile investment long term.

Whether you're working on a kitchen, bathroom, or full remodel, using the right underlayment for tile can mean the difference between a floor that lasts and one that lets you down. We offer high-performance options that handle moisture, impact, and thermal changes, all without complicating the installation process.

ProLux offers a range of tile floor underlayment systems that are lightweight, easy to install, and some compatible with radiant heating systems. They’re engineered to save time, support tile adhesion, and ensure every tile stays exactly where it should be.

If you’re looking for a solution that balances strength, flexibility, and performance, our underlayment for tiles is up to the job.

Why Tile Underlayment from Prolux Materials Is Worth Every Layer

  • Peace of Mind Under Every Tile - Tile underlayments ensure a stable, durable foundation for any tile project—preventing costly failures and extending the life of your beautiful floor.
  • Protects Against Cracks and Shifting - By absorbing movement and subfloor stress, tile underlayment membranes prevent tiles and grout from cracking, lifting, or delaminating over time, ensuring a long-lasting, reliable installation.
  • Creates a Flat, Even Surface for Tiling - Underlayment membranes provide a smooth and stable base for your installation, improving tile adhesion and finish quality across the entire floor.
  • Labor Saving Installation - Tile underlayment membranes are both lightweight and easy to cut, reducing installation time and labor—ideal for both DIYers and professionals.
  • Built In Moisture Protection - Tile underlayments provide a protective barrier that resists moisture while allowing vapor to dissipate. This helps prevent mold, mildew, and water damage—keeping your tiles dry, healthy, and long-lasting.

Start your tile project the right way. Explore ProLux Materials tile underlayment systems and build a better floor from the bottom up.

FREQUENTLY ASKED QUESTIONS

What is tile underlayment and why is it important?

Tile underlayment is typically installed over clean, level subfloors. Most products are roll-out or panel-based and work with thinset or adhesive, depending on your floor system.

Does underlayment for tiles help prevent cracking?

Yes. Using underlayment for tiles helps prevent cracks by absorbing subfloor movement and reducing tension between layers. It also helps with moisture resistance and sound reduction.

Is tile underlayment compatible with all tile types?

Tile underlayment is compatible with a wide range of tile types, including ceramic, porcelain, and natural stone. Just make sure to choose the right underlayment based on your subfloor and tile thickness.
