All our wood/laminate underlays including Royale TimberHush 3mm and Sonic Gold Commercial Underlay are recommended for use under floating floor installations such as laminates where there is no direct fixing to the sub floor required. If you intend to use an underlay under your new floorboards you will reduce the impact sound reduction qualities by fixing with nails. We recommend you seek advice from building regulations as there maybe repercussions in a flat environment if you have someone living below. Ultimately the Sonic Commercial Underlay is the best all rounder.
