BASIC with rounded edges is covered by a surface paperboard and has rounded edges for jointing and puttying. As such, it can be installed like a gypsum board and its surface treated in any traditional way. Keep in mind that the since the surface is more textured, the result may not be as perfectly smooth as with a gypsum board and requires more work by the painter. Also keep in mind Reaction to Fire Classification (E) that might limit its use or require additional treatment. Since it is also strong as an OSB board, it can replace two layers at once, saving 90% of CO2 emissions with a lower price tag.
The manufacturer has the sole ownership, liability, and responsibility for the EPD. EPDs within the same product category but registered in different EPD programmes may not be comparable. For two EPDs to be comparable, they must be based on the same PCR (including the same version number) or be based on fully-aligned PCRs or versions of PCRs; cover products with identical functions, technical performances and use (e.g. identical declared/functional units); have equivalent system boundaries and descriptions of data; apply equivalent data quality requirements, methods of data collection, and allocation methods; apply identical cut-off rules and impact assessment methods (including the same version of characterisation factors); have equivalent content declarations; and be valid at the time of comparison.
