Is plasterboard / Drywall not considered a product for LEED V4 ?
This is what I understood from the LEED guide, page 469,
In our project we aim to have 20 products with EPD Type II , so even if I have 3 drywall products with EPD Type III, they will not be counted in the LEED?
for your info, only dry wall have this EPD, the uprights and rails of these drywall do not have EPD reports?

Drywall is 100% counted in LEED v4 and v4.1 (which you should be using v4.1 for any of the material credits). Each type of drywall that has an epd counts as a separate product (i.e. Type X, Mold Resistant, Fire-rated) as they all serve different purposes.
You will have no problem using drywall to hit your EPD target, as long as it is a distinct product with a qualifying EPD.

Thank you very much for your feedback which I appreciated.
FYI, I only have EPDs for plasterboard, and I don't have EPDs for their studs and rails. Is it still possible in this case to count these plates as product?
I am lost with a sentence in the guide - page 469,
"" Defining a Product
Several credits in this category calculate achievement on the basis of number of products instead of product cost.
For these credits, a “product” or a “permanently installed building product” is defined by its function in the project.
A product includes the physical components and services needed to serve the intended function. If there are similar
products within a specification, each contributes as a separate product. Here are a few scenarios.
Products that arrive at the project site ready for installation:
·· Metal studs, wallboard, and concrete masonry units are all separate products.
·· For wallboard, the gypsum, binder, and backing are all required for the product to function, so each ingredient
does not count as a separate product "" .

Yes, it is still considered a product. The wallboard is assembled at the site using metal studs so wallboard and metal studs are considered as two separate products. If you have EPDs for metal studs and Wallboard then it will count as 2 EPDs not one EPD.
For wallboard, the gypsum, binder, and backing are all required for the product to function, so each ingredient does not count as a separate product (it means that the combination of these elements makes up wallboard, normally in a manufacturing facility, and it comes to the site as wallboard, therefore gypsum, binder, backing are not different products).
