m² weight of flite test foam?

[northPOW]

Hi,

i try to compare the weight of: flite test foam vs depron aero

depron aero 3mm - 100g per m²
depron aero 6mm - 175g per m²

But what is the m² weight of ft foam?

From here:

https://www.flitetest.com/articles/comparing-foam-board

DTFB is about 0.2 g/sqin (mixed units! AGH!!!)

so there's roughly 1550 sqin in a m2, so

~310g/m2

That's for a 5mm thick sheet, and roughly half that weight is in the paper. The interior foam is not as fine-grained as depron, but otherwise the properties are pretty close when you get the paper off the boards. laminate on some paper (@~75g/m2, wiht adhesive) and the 6mm foam will be very close.
