More curiosity but I may be interested.
I spoke to a local builder and got Bunnings-branded wall sarking, the alternative to Tyvek as a tent footprint for all my tents.
Looks like an old blue woven nylon tarp, coated and metallised on one side.
4m long x 1.2m wide weight 540g - say 110g/sq m (110gsm) I could get away with 3m, but double over the footprint at the front entrance to the tent.
How heavy is the Tyvek wall cladding? Comparable?
Cheers,

According to the
SPEC SHEET, a 2.7 metre roll 30 metres wide is 5 KG.
So that calculates to 166 grams per 1 metre long x 2.7 metres wide.
About 62 grams per square metre.
And no need to double over the footprint area at the door, unless you intend to fold it out and have a crinkly welcome mat.
That would make 3 metres exactly 500 grams. But the postage bag also weighs a bit, so the one time I squeezed 3 metres into a 500 gram prepaid satchel, it only just fit (physical size, with some clever folding), and it was about 27 grams over weight, but they decided to let it through.
It's a lot easier to fit 3 metres in one of the larger $10.70
prepaid satchels.
By the way, it won't be me distributing the tyvek this time, another local forum member has kindly offered to take on the job of volunteering their time and effort for the benefit of forum members.
