Yep - Even loose fitting, it was pretty effective - the PIR is so light it all gets sucked in.

I wish I could go back in time and do it again

How long do you reckon is long enough?

Mine is 700 mm. Occasionally I stand under it and wish it was a tad longer but I think it's a good compromise. I did originally have it down to be 500 mm but when I put the first roof joist down and looked at it from the underside it just felt a little short.

I'm surprised you can get away with roof joists of 2x5s, your span is 3.5 m?

Well fuck me.

Somewhere along the line, I've managed to mix the roof rafters up in my Sketchup files.

170mm is the depth I need for the span.

That was close...
