What do building rules usually require?
A percentage of hard floor covered by rugs, often 70 or 80 percent in living areas. The rule exists because of the neighbour downstairs, not because of aesthetics.
Which layer is doing the work?
The pad. A rug alone absorbs airborne sound reasonably well and impact sound poorly. Dense felt underneath is what dampens footfall before it reaches the slab.
Does the thicker pad always win here?
Acoustically, yes — specify Luxe 1/4 inch unless door clearance or radiant heat forces you down to Luxe Lite.
