As I’ve been leaning fiberglass work off you tube it’s all in the USA and they pretty much use 1708 biaxial combi mat for most projects so I want to get the same , 17means it’s 17oz per square yard so it’s 17oz of biax and 8oz of csm this is per sq yard now my maths isn’t the greatest unless its to justify buying new tools ??? but I’m trying to figure out the Closest uk equivalent, Now ours stuff is in grams and is worked out per sq meter , my choices are 450/225 600/300 or 800 /450 anyone got clue on this as maths isn’t my strong point
