Interesting... when you lift the Dynamat Box, it seems VERY heavy but according to Dynamat... it's not. Charlie (a good tech from Dynamat) said
"To answer your question, the Dynamat weighs around .5 lbs per sq ft."
I installed 2 whole boxes of the Xtreme Mega Packs so when you do the math...
Each box = 72 sq ft X .5/lbs per sq ft. = approx 36 lbs.
Doesn't sound right, but I have 2 answers that are the same (one from charlie and another from a tech spec sheet)...but I mean, this stuff really does feel much heavier just going from memory but I guess they are right.
Soooo
