Description
TRADELINE Unbraced Twin Frame I Stud systems are lightweight, non-load-bearing, friction fit systems.
They can be used within all sectors but primarily within residential to achieve the acoustic requirements of Approved Document E and enhancements of +5 or +8dB.
Due to the TRADELINE frameworks being isolated from each other, excellent levels of sound insulation can be
achieved up to Rw 70 dB. Whilst also providing up to 120 minutes of fire resistance.
Features and benefits:
- Acoustics up to 70 Rw dB with Ctr of -10.
- Suitable for use with Code for Sustainable Homes or BREEAM.
- Suitable for party wall construction with requirements of +3 to +8 dB DnT,w on ADE requirements of 45 DnT,w + Ctr.
- Fire resistance up to 120 mins BS 476:Part 22.
- Structural columns can be incorporated within the partition cavity due to unbraced twin-frame design.
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.
Installing framing for partitions:
- Partition height (maximum) calculated based on a limiting deflection of L/240 at 200 Pascals.
