HOME Construction Methods sound insulation wall method A-2000 WI series

High performance sound insulation wall system with TLD-56`60sound insulation performance.
A-2000 WI series

A-2000EWI A-2000 WI is the basic type of the series(TLD-56)
A-2000EWI-S The system reduces vibration generated in walls by tapping on the wall.(TLD-57)
A-2000EWI Strong The system offering enhanced rigidity(TLD-60)

More than several hundreds of super-high rise buildings employ this high-performance sound insulation wall system for border walls throughout Japan.

[Recommended use location]
  • Suitable for areas requiring high levels of sound insulation, such as housing complexes, hotels
  • Used as fire separation walls in super high-rise condominiums and public housing

[Features] (In case of A-2000EWI)
  • High levels of sound insulation performance
    At only 136 mm thick, it can provide high levels of sound insulation equivalent to 260 mm reinforced concrete walls
    * Sound insulation performance : TLD-56
    Sound insulation construction certification no.: SOI-0112, Quality assurance law compliance: 1122 (Grade 4)
  • Maximum safety
    Hard-type gypsum board gTiger Super Hardh, fire resistant gypsum board gTiger Board Type Zh and light gauge steel framings (studs) are combined to provide a superior wall system to the conventional gypsum wall systems. The system is capable of achieving higher levels of performances than the official standards.

  • 60 minutes fire resistance (Non-loadbearing)
    Can be used in all levels of floors as separation walls or fire partition walls.
    Fire resistance structure certification no. FP060NP-0198 (Non-loadbearing : Wall systems which do not bear building loads)Fire resistance structure certification no. FP060NP-0198 (Non-loadbearing : Wall systems which do not bear building loads)

  • Light weight
    A-2000 WI wall systems weigh much less than reinforced concrete walls. This reduces total weight of buildings. In addition, spaces for foundation or bearing pile can be significantly saved due to thinner structure section of columns or beams.

[Others]
Achieved all required performance for dry separation walls.
