Rupert - styrene deteriorates in sun doesn't it. The stuff they use in VI and USA etc in their raft systems is called blue board (different to our blue board - their is styrene). I think it may be UV trated. They also paint the bottom with a natural latex I think. I would be concerned with leaching issues if it weren't sealed in some way.

EB- do you recall how wide the cutouts were--75mm sq?
and guessing the width would be 1-1.2 mtrs.
asuming 75mm X 1.2 the cost would be in the $70 range to do a
5.0mtr x 1.2 GB(prolly 2 sheets 2.4x1.2 lattice ) anyone bought lattice of the kind we're talking of ?
C1
timber wood(pun) be a one off purchase

the styrene wuld be fine if you could get hold of some without the fire retardants (leaching wise)

what about stuff like cool room insulation Steve??

i'd say its all treated with flame retardant. HOWEVER......the outside is like a painted metal isn't it? (i do more A/C)

fire rated?

dunno to be honest

50mm I would guess... and about as wide as a sheet of roofing iron......

mmm....That just up the cost by about 50% so make that $105

Just done some quick googling and yep looks like it's all got fire retardant additives of some degree or other.....

So what do guys like Wilson use for their floating rafts????

... and normal styrene boxs, used extensively as hydro kits .....

... or even the humble broccoli box lids???

and should have read--- as wide as sheeting iron 760mm reducing cost by 35%
$80-

It was something that he was looking at phasing out and he's gunna move towards his own pressed nft made from 90mm storm water pipe..

Yeh looks like a better option. Wouldn't want to use shitty old timber anyway

Ummm Jarrah aint a Cheep alternative to anythin these days

Wiilow was looking at using some sort of shrink wrap product to cover his styrene.
