Try one of the large hardwares like the one that starts with B and ends with unnings. The rolls are about 1.5 metres wide and really long, I used offcuts from the roofers who reroofed my house.

Lets have a design the best Astro Hut competition. it has to be practical, easy to build, offer all the mod cons including a view of the sky! the IIS Astro Hut or IISAH. It'l be great, design by committee, tried and tested by the IIS and authenticated to be a quality astro tool! (sorry sounds a bit like a meade ad). But hey there must be some guys on this site with the knowledge to draw up the suggestions and post it on the projects page.
Right now I have your attention, I scanned through the thread so I know little of what has transpired.
I own a commercial ceiling company and part of this is providing insulating materials of differing types for differing purposes. In other words I am an expert in this field. So if you have not bought anything you could try the following.
Auspoly or Tontine make polyester insulation which is used everywhere in the commercial building sector. It is cheap and won't break down or drive you insane with itching when you install it. I would go for something with a rating of R5. It is thick about 100mm. And then line your shed with WR (water resistance plasterboard) or villaboard (fibre cement). By all means paint the roof white if you want.
Then use the same stuff to line the walls. You might loose a little room but it is really worth it. You shed will be so cool during the day, and this will help with evening cooling.
Don't use roofing insulation. It won't work properly. Don't use glass wool, it will get into everything and you will itch for hours and it will break down.

Best of luck.
Great advice Paul, Thanks for the info.
I was thinking of using glass wool/roofing insulation. Not now.
Sounds cool Paul.
I was looking at it from a Joe Blows capability with minimal effort on an existing structure.
Building from scratch it sounds feasible depending on cost.
What's a good price on the R5?
Nothing for Auspoly, except a price list from Tasmania which was totally over priced at 12 dollars a metre. Glad I buy stuff from them. They are located in Adelaide though. Tontine is located in Melbourne.
I lined my shed with Polystyrene and then 3mm braseing ply it is very cool and light, the roof pushes of with one hand and it was cheap to build. Dennis (nightshift) and others will be up this weekend, I will get them to give me an apraisal. astroron
I am considering insulating the roof of my observatory. However my present fix for trying to protect my lx90 from those hot days is to make an insulated box cover out of polystyrene fruit boxes. I have attached photos.
