- Rw figures from 58 to 70 Rw dB.
- Speedline thermal braced twin frame C stud achieves Rw 65 dB and a theoretical U-value of 0.0 W/m²K.
Structural performance:
- Strength grade to BS 5234-2:1992 Annexes A-F.
Fire performance:
- Fire resistance to BS 476:1987:Part 22.
Acoustic performance:
- Calculated weighted sound reduction index (Rw) to BS EN ISO 10140-2: 2010.
