GTEC dB acoustic board

the main thing you want to look at when comparing 'acoustic' plasterboard is the surface density (kg/m² ), the higher the number the more mass it has and better it performs and a mass barrier

 

From what i can see 12.5mm GTEC dB is 10.2 to 10.7 kg/m² , and 15mm is 12.5 to 13.1 kg/m².

 

other boards as below;

 

Gyproc wallboard                          12.5mm - 8.0 kg/m2, 15mm - 9.8 kg/m2

Gyproc fireline                                12.5mm - 9.8 kg/m2, 15mm - 11.7 kg/m2

Gyproc SoundBloc                         12.5mm - 10.6 kg/m2, 15mm - 12.6 kg/m2

Gyproc plank                                   19mm - 15 kg/m2

Gyproc SoundBloc F                      15mm - 14.1 kg/m2

Knauf Soundshield                        10mm - 8.4 kg/m2, 13mm – 12.3 kg/m2

Knauf Standard Wallboard           15mm - 10.2kg/m2

Knauf Vapour Panel                      15mm - 10.2kg/m2

Knauf Moisture Panel                   15mm - 10.2kg/m2

Knauf Sound Panel                        12.5mm - 10kg/m2

Knauf Fire Panel                             15mm - 12kg/m2

Knauf Impact Panel                       15mm - 12.8kg/m2

Knauf Soundshield Plus                15mm - 12.8kg/m2

Knauf Performance Plus               15mm - 12.8kg/m2

Knauf Plank                                     19mm - 14kg/m2

Knauf Core Board                           19mm - 16.3kg/m2

 

So between 15mm GTEC dB, Soundbloc, and Knauf Soundshield Plus, the  GTEC dB is marginally more dense, but if you go for Gyproc SoundBloc F you get a bigger increase.

I've got a big stack of it waiting for my attention...

 

Stack of what exactly?

We are at the same stage of looking at plasterboarding spec.  Its a minefield.  The list above is really useful - thanks @Moonshine

15mm acoustic on ceilings.  But has anyone used acoustic on walls too?  Anyone not used acoustic on walls and finding it noisy?

Worth putting acoustic on the wall between the WC / utility and the lounge, for example?
