The 1/4" ProPanel Backer Board is specifically designed for floor tile applications and delivers exceptional performance in residential and light commercial installations.

ProPanel achieved residential and light commercial ratings in the demanding Robinson Floor Test, making it an ideal lightweight alternative to traditional cement backer boards.

ProPanel™ Foam Based Backer Board is lightweight yet heavy-duty.

Manufactured using high-density expanded polystyrene reinforced on both sides with alkaline-resistant fiberglass mesh and waterproof cement coating, ProPanel provides a durable, waterproof, and mold-resistant substrate for tile installations.

Perfect for:

  • Tile floor installations
  • Shower walls and waterproof shower systems
  • Bathtub surrounds
  • Bathroom remodels
  • Kitchen countertops
  • Residential and light commercial tile projects

Waterproof Protection Built In

Unlike traditional cement boards, ProPanel is completely waterproof and does not require a liquid waterproofing membrane over the entire surface. Only seams and fastener penetrations require waterproof treatment using approved polyurethane sealant or liquid waterproofing membrane.

ProPanel has successfully passed:

  • ANSI A118.10 Section 4.5 waterproof testing
  • ASTM D-4068 Annex A2 hydrostatic pressure testing
  • ASTM G-21 & G-22 resistance to fungi and bacteria testing

ProPanel delivers superior moisture and mold resistance, helping prevent common moisture-related failures in tile installations.

Key Features:

  • 100% waterproof foam backer board
  • Moisture and mold resistant construction
  • Lightweight design - approximately 2 lbs per panel
  • Easy to score, cut, and install
  • Cleaner indoor cutting with minimal dust
  • Adds insulation value to wall assemblies
  • Will not rot, deteriorate, or break down over time
