GoBoard® is the innovative tile backer board by Johns Manville that is ultra-lightweight, waterproof, durable, easy to cut, and install.

GoBoard® is the durable, ultra-lightweight, waterproof tile backer board from Johns Manville.

  • Fast Installation: Complete shower tile projects in half the time or less. Install GoBoard with GoBoard Sealant, take a break and tile the same day. Grout the next day and the project is done*.
  • Ultra-Lightweight: Even though it’s much lighter weight than cement and other heavy boards, GoBoard is engineered to be dependable, and it can be installed in residential and light commercial tile applications.
  • Easy To Cut, Handle & Install: GoBoard can be quickly cut right where it’s installed with a basic utility knife—without crumbling or disintegrating. It’s also much easier to handle than cement and other heavy boards.
  • Waterproof Built-In: GoBoard saves time and money because you seal only the board joints and fastener locations for a waterproof tile assembly**.

* A typical shower project, waterproof installation, following manufacturer's installation.

** Board joints and fastener locations require a waterproof sealant per GoBoard installation instructions. 

Johns Manville

GoBoard is available in the following thicknesses:

  • ¼" for floors and countertops (3'x5' and 4'x8' sheets)
  • ½" and ⅝" for walls, showers, ceilings and floors  (⅝" in 4'x8' sheets)
  • 1", 1½" and 2" for walls, benches, shelves, tub surrounds, vanities and countertops  (4'x8' sheets)
