Hi...I live in a flat and I am planning on replacing the carpets in hallway and living room with engineered wood flooring. The issue that I am facing is with what to install under the new flooring in order to comply with Part E. The existing subfloor consists of 3 layers of floating sheet materials (20mm plasterboard, 50mm Celotex and 18mm T&G chipboard flooring) sitting on 18mm plywood and timber joists. Below the plywood decking is 200mm insulation wool.
My questions are... what are the acoustic properties of the existing floor structure and what level of acoustic insulation do I need with the new flooring?
Many thanks
