Application

  • Incorporated within a ceiling or wall construction.
  • Isocheck Isowave 23 system is for the treatment of excessive flanking sound that bypasses a separating floor via lightweight structural walls.
  • Particularly suitable for resolving separating floor sound test failures which often occur with a timber structural separating floor within a 1950s to 1990s clinker/lightweight block facade inner skin.
  • Used for a high performance light weight wall construction that is intended to separate two dwellings.

Description

Isocheck Isowave 23 consists of a 10 mm Isowave acoustic foam measured to BS 4443 and BS EN ISO 845:2009 bonded to 12.5 mm high density, square edged fibre-reinforced (30 minute fire rated) gypsum board. It reduces unwanted flanking noise in order to comply with Approved Document E 2003 and subsequent amendments.


Features and benefits:

  • Reduces direct airborne sound transmission and unwanted flanking noise.
  • Excellent absorber with high damping characteristics when bonded to an acoustically reflective stiff surface.
  • Complies with requirements of EU Regulation No 2037/2000 for ozone depletion and offers good thermal properties.
  • NHBC tested.
