Key Differences Between GoBoard and Kerdi For Your Shower

Now let’s analyze the main differences and find out which one is more suitable for your shower-

  • Weight
GoBoard Tile Backer Board

You might think that weight is not an issue for the substrate as it will eventually stay under the tiles.

But in reality, it creates a big difference when you install them on your wall.

Lightweight boards are easily stuck to the wall and it reduces the installation time also.

You won’t need a huge amount of mortar to place them on the wall. Lightweight boards are also super durable.

So, if we want to compare the GoBoard and Kerdi based on their weight, the GoBoard wins. Because it is ultra-lightweight and, most surprisingly, it is 80% lighter than the traditional cement backer boards.

The Kerdi board is also lightweight but not like the GoBoard. So, GoBoard wins here.

  • Manufacturer

GoBoard is manufactured by Johns Manville, which is an American-based company. They also manufacture insulation, commercial roofing, and building materials.

Schluter®-Systems, which is a family-owned group of companies, manufactures the Kerdi board. Both companies are reputed and well known, but Schluter®-Systems created customer dissatisfaction for a certain period of time due to the Kerdi board shortage.

  • Materials

The inside of GoBoard is made of polyisocyanurate closed-cell foam, and the outside is made of a fiberglass mat. GoBoard is a kind of backer board because the main elements of a backer board are cement, silica, fiberglass, etc.

Kerdi board, on the other hand, is an extruded polystyrene foam panel. Kerdi board is a kind of waterproofer because these kinds of boards are made of XPS foam.

  • Installation

As the GoBoard is very lightweight, it becomes easy to install. You can cut it with a simple utility knife. It also produces less dust during installation, and this makes the installation process easier.

The Kerdi board is more rigid than the GoBoard. So, it is difficult to cut a Kerdi board with a utility knife. The overall installation process of Kerdi boards is lengthier than the GoBoard.

GoBoard or Kerdi?

Now that we know all the differences between GoBoard and Kerdi, let’s come to a decision. Which one stands out? GoBoard or Kerdi?

KERDI BOARD

Well, to come to a decision, you have to make up your mind first.

Do you want something that is difficult to install but cheap? Or do you want something easy to install but expensive?

If you choose the first one, then the Kerdi board is for you. Because, to install the Kerdi board, you will have to deal with some hassle.

First of all, you might face issues while bonding.

Secondly, if you want to install it all by yourself without getting any help from a professional, chances are there will be some errors and you won’t be able to solve this easily.

Finally, it will take some time to stick on the wall, and you can’t place the tiles immediately.

On the other hand, if you want an easy installation, then go for GoBoard. Its ultra-lightweight design will give you the perks of easy cutting and installation.

Though it’s a little bit costlier than the Kerdi board, you can save money by installing it on your own.

Also, there is no expensive tool required for this installation, which means that, in the end, the cost is almost the same in both cases. So why not choose the durable, lightweight, built-in waterproof, easy-to-install GoBoard?
