Hi guys,

I picked up a garden shed (3mtrs long x 1.2mtrs wide x 1.8mtrs high) to use as an observatory in my backyard.

It's just a lift off roof currently but I am looking to insulate the walls and roof to try and minimize the heat coming through during the day.

Budget is tight, but looking for some ideas. Thinking Polystyrene foam sheets at this stage, say 15-25mm thick. Just use silicon or some other adhesive to glue to the walls.

Given its a small shed I don't want to use anything too thick, but also want to get some protection from radiant heat.

Anyone else got some ideas or advice? Or do I not need to be concerned about insulation?? (my telescope sits on a pretty high pier so I can see over the side walls without obstruction and therfore is in close proximity with the roof).
