Hello everybody,

We used on our project plasterboards from the same manufacturer (Saint gobain), which have the same characteristics (acoustics, thermal resistance,...) but they are different in thickness (BA13, BA15 and BA18) and each them has its own Datasheet, can we Consider them three distincts products? and therefore count three EPDs and three HPDs? Or is it considered the same product?

For information, there is only one HPD report which covers the 3 products but the EPD reports are established separetely (3 EPD reports). 

Thank you :)
