I have loads of different grades of Ply ... anybody know of a good on-line
source that helps identify different standards for ply.

For example I have 1/2" ply .. in shuttering grade, WBP and Marine ....
understand the difference OK, but I also have some 1/2" ply that is made
from more individual plys than 'the standards'

It is very good quality, very dense and seems to be generally referred to as
Birch ply ... but I assumed Birch was referring to finish on one face only.
?


Any Ply experts want to enlighten ?

Birch ply is ALL birch IIRC. Its excellent stuff. Its NOT fully
waterproof, but apart from that its the best.

Marine ply uses a fuly waterproof glue. Top line stuff usually.

I'd use the birch for gerenarl work, and marine on e.g. bathroom floors
and splash panels.

General purpose ply is OK for riough work - house cladding under a render coat etc.
