When installing hardwood flooring, you need to consider what you will choose to go under your flooring to ensure its durability and resilience. Whichever way you're looking to install your hardwood flooring (whether with glue, nails, or as a floating floor), it's important to select the right underlay beforehand.

So, what goes under hardwood flooring? 

Underlay goes underneath hardwood flooring and the type of underlay you need is decided by the subfloor, not the flooring. If you have a level concrete subfloor, most underlays will work fine under hardwood flooring. If you instead find that your subflooring consists of floorboards, we would recommend overlaying them with chipboard/plywood as floorboards are not usually level and this can cause issues when installing new hardwood flooring. 

Here's a look at some of the underlays you can place under your hardwood flooring on a level subfloor:
