GoBoard™ by Johns Manville (Made in the USA)

GoBoard™ is the ultra-light, waterproof tile backer board from Johns Manville. It’s engineered for durability, yet is up to 80% lighter than cement boards. GoBoard™ is easy to handle and can be cut right where it’s installed with a basic utility knife without crumbling or disintegrating. And, best of all, it has waterproofing already built-in.

GoBoard™ is not intended to replace wedi® Richmond Tile & Bath. We are adding it to our offering as a less expensive alternative for underlayment and wall, in wet areas where a full wedi® shower system is not being used.


  • As a thermal break on concrete floors under tile
  • To prevent heat sink under radiant heat
  • On walls in wet areas where shower receptor, bathtub, fiberglass pans or lead pans are being used
  • Many of our customers will still prefer wedi™ in these situations for various reasons
  • There is no reason any consumer would not take advantage of adding longevity and low maintenance to a tile installation for a few bucks more than cement backer board by using this GoBoard™ product.
