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 :)

Hi Sara, I have the same question with a similar situation. Did each of the products counted separately even though they had the same HPD?

Hi Cristina,
An HPD that covers several products will only count one time. If there are seperate HPDs, even if the products are very similar, these can each count individually. The same rule applies for EPDs.
Hope that helps!
