· Solid monolithic elevation provides:
- 40 STC with no insulation
- 48 STC with insulation

· Double Glazed full-height elevation provides:
- 38 STC
- A balance of acoustic privacy and light penetration

· Acoustic fascias provide:
- 40 STC with recycled cotton insulation
- 32 STC with no insulation
