No need for wire then as its more rigid and about 10mm thick. That will also keep your observatory less hot in summer. Its got an aluminium finish on both sides so I sprayed mine flat black to avoid light reflections.

Easy to handle and cuts with a knife, a very good product.

The problem with sarking is it will deteriorate eventually. Its not really a long lasting product but I suppose it will last 20 years so long as its not getting regularly wet.
Interesting. There's always an alternative to complicate the issue isn't there The aircell, looking on the Kingspan website, looks very similar to Sisalation. It's rolled like Sisalation, how is it more rigid or longer lasting? I'm hoping to go in to bunnings this afternoon on the way home from work to see them and compare.
