 Alterna vs.Ceramic & Stone

Our durable engineered stone construction makes Alterna tiles a perfect alternative to ceramic and stone:

  • Wamer to the touch than ceramic or stone
  • More comfortable underfoot
  • Easy-to-clean surface resists stains and soil
  • Strong, yet flexible enough to cover subfloor irregularities that can crack ceramic or stone tile

 Flooring Patterns

Our most popular collections are available in multiple shapes and sizes, so you can create a unique floor pattern that’s all your own.

You can grout Alterna, just like ceramic, or install it without grout.

Armstrong’s acrylic grout is ready to use, requires no sealing, and resists moisture, stains, and cracking.
