When buying insulation boards its important to get the correct board for your type of heating and also your subfloor.

In most homes you will have either a concrete sub floor or wood subfloor (chipboard or floorboards). If you have a wood subfloor then this means that you will require the best and most stable board - The HeatStore Tile Backer Board.

The difference between the Tile Backer Board and the XPS boards is that the tile backer boards have a polymer modified cement coating both sides - this makes them very strong and they resist movement in the sub floor.

Pro's for XPS boards

They are cheaper to buy

They have the same insulation properties as the tile backer boards

They can be used for both tile and wood floor heating systems

Con's for XPS boards

They take longer to install - because they are lighter and more delicate they need to be pressed into any tile adhesive used to fit them and you need to make sure that the board is fully adhered to the adhesive.

They can not be used on a wooden subfloor like floor boards or chipboard

Pro's for tile backer boards

They can be screwed (with washers) to wooden subfloors which makes installing over this surface much quicker

They are very tough with the cement coating and you can stand (or even jump) on them when installing onto tile adhesive

Cons for tile backer boards

They are more expensive than XPS boards

They can only be used with tile heating systems
