The key features of this solution are that :-

a) Site tested sound insulation performance is far in excess of regulation E test requirements


b) You are best to retain the existing lathe and plaster or plasterboard ceiling ( as this adds to the soundproofing of the solution).


c) Minimise ceiling height loss a total drop from the ceiling of just 82mm


d) Minimal work on floor- just laying acoustic mat (6mm thick)


e) It is 1 hour fire proof- in common with all our solutions (building control often prefer substituting the 12.5 mm layer with a 12.5 mm fire check board).


The ISOSONIC TIMBERFLOOR provides safeguards against failure with 'pre completion testing'.
