If you decide to float your bamboo flooring over an underlay then you will need to think about which particular underlay will suit your needs.  The three main types of underlay are: sound reducing underlay, thermal barrier underlay and underlay for underfloor heating. Which type of underlay is best for me? When choosing an underlay, it is important to remember that the colour and thickness of the underlay does not make any difference to thermal protection or sound proofing.  If you require sound proofing, you should look at the decibel rating, and if you require thermal insulation you should look at the Tog rating. For more detailed information about underlays, see What underlay should I use with my bamboo floor?
