High mass gypsum overlay board for use in flooring applications .
Isosonic Screed Plank 20 ( ISP20 ) boards are high mass gypsum fibre flooring boards with lapped joints . They are designed to be used as a dry screed board , as a substitute for a wet screed , or in combination with Isorubber underlays and soft coverings to provide a high performance acoustic floor solution .
Hard & robust cementitious gypsum plank with high density & mass .
Suitable for use as a floating floor " dry screed " - saving on construction time and screed pumping .
Provides a stable and water resistant Surface .
Low thermal resistance and even heat distribution make it ideal for use with UFH systems .

The high mass property of the plank combined with the durable high resilience of Isorubber Standard provides the high level airborne and impact sound absorption of the system .

Multi-purpose acoustic insulation for new build & refurbishment to meet pre-completion testing ( AD Part E 2003 ) requirements
Isorubber Standard is a cost effective acoustic mat for use in projects that are being pre-completion tested .
Available in thicknesses of 3mm , 5mm & 8mm , Isorubber Standard is not just for use with ISP20 . It can also be used in other applications , such as below screed or as a resilient covering beneath wooden floor finishes and tiles .
Below wooden floor finish
Suitable for almost all types of floor High performance acoustic isolation and vibration reduction .
Resilient & durable finish .
The required thickness of Isorubber Standard is dependant on application floor build up . To find out more or to discuss a specific project please contact our Technical Department .
