It is possible, but note that it is not recommended and it will make the warranty void.
The sub-floor must be perfectly level and damp-proof. Most probably it will be necessary to use a levelling compound and an appropriate damp proof layer. In addition, you will need a resin that provides sufficient adherence to the Laminate backing.
Why would you want to use full-surface gluing?
If the correct Quick-Step underlay is used, combining underfloor heating with a floating installation is no problem at all. Check out the installation manual for further information.
You need to make a distinction between transmission sound and reflection sound. Transmission sound can only be reduced with a floating installation. Gluing down the floor covering will improve sound insulation.
Reflection sound can indeed be reduced with the full-surface gluing method. But Quick-Step also has the ideal solution for this: high-quality Quick-Step underlays. These allow you to combine the benefits of a floating floor with acoustic insulation.
