Why not just pull it taut and put a couple of screws in at each end?
It might sag a bit over time, but will you see it?


It will actually be visible in this case - it's a storage shed. But
more importantly, it will be supported on battens screwed to the
rafters (sitting on top of the battens). If it was to sag
significantly, it would fall off the battens, hence the question.

I'm not sure screwing would be very successful, given the low denisty
nature of the material.


I can't help much with the long-term sagging, but I don't see why the
low density of polystyrene would be an impediment to screwing into it.
Obviously you couldn't torque them up, but they would still be effective
anchors. You could use small nails, even, and push the sheeting down on
top.

Ben.

I have built several model planes out of it,

Do you put them next to your How Things Work annual.
