Limitations to know
Sound ratings belong to the wall system, not the insulation — SCG gives STC for specified wall systems.
Where does the data come from?
SCG Acoustic catalogue
Technical data from the manufacturer's documents SCG · Checked 26 Sept 2026
Technical specifications
All values come from the manufacturer's documents, with conditions and test standards. Values the documents do not state are not shown.

System-level values
Sound insulation ratings (STC / Rw) and fire-resistance ratings belong to the complete tested wall, ceiling or floor system — not to the insulation on its own.
SCG gives STC values for specified walls — for example SCG SmartBoard 8 mm both sides on steel framing, with and without ZoundBlock. See SCG's installation guide.
