Description

The Isowave 23 system is designed for the treatment of excessive nearby sound that bypasses a separating floor through lightweight structural walls. The Isowave 23 System is ideal for upgrading a 4″ masonry or timber partitions or an external masonry wall which is causing adjoining noise transmission – often revealed as the cause of a separating floor test failure – or used on independent studwork to upgrade an existing separating wall that has poor performance quality for airborne sound transmission. The system includes a reinforced high-density gypsum board bonded to 10mm Isowave acoustic foam, which is extremely eco-friendly since using only water as the blowing agent and free of any harmful gasses, including CFC, HFC or HCFC. When the 23 systems are incorporated within a wall construction Isowave 23 will individually achieve ½ hour fire protection.

Isowave 23 consists of a 10mm Isowave acoustic foam bonded to 12.5mm high density, square edged fibre-reinforced gypsum board.

Key Features:

  • Provides flanking and airborne sound transmission reduction
  • Applicable to new build, refurbishment, and conversation
  • Includes an acoustic foam measured to BS 4443 and BS EN ISO 845:2009
  • Provides good thermal properties
  • Able to meet values prescribed by the Approved Document E of the Building Regulations for ozone depletion
  • Environmentally friendly
  • Great damping characteristics

Applying acoustic materials to your floor and wall spaces can increase the acoustic properties within the building. Isocheck can reduce impact noise from the room structure to the room below or room adjoining such as footsteps, furniture movement, tv noise, etc. Making a more comfortable environment for rooms below or neighbours adjoining. It can also reduce sound echoes within the space.

For longer term protection on site, the product should either be stored indoors, or under cover and off the ground in weatherproof conditions. The boards packs are designed for short term protection only and they should not be left permanently exposed to the elements.

Isocheck Isowave 23 can be installed in a range of methods. These methods include:

Conversions Systems
Refurbishments Systems
New Build Systems
Masonry and separating walls Applications
Separating floor and ceiling applications

Janine says:

This is a great company to deal with. Not only do they have a really wide range of insulation boards, but they offered the best prices compared to other online companies. They were also efficient and helpful, keeping us informed at every stage of the process and importantly will put themselves out to give you the best deal all round. Our large order arrived on time and in good condition. What more can I say?
