Sticking Aerogel to steel

The thermal property of tilebacker boards is nowhere near comparable with aerotherm though.

It's not but you can plaster straight onto it. If you are planning to clad this in plasterboard you could use 20mm XPS and have a thinner overall build up.

Same stuff as in the photo by @Mulberry View. 5 years since I bought it.

Is this aerogel or spacetherm? From the suppliers I’ve approached, aerogel is like a stiff board/sheet (these pictures look like a loose fabric). It appears that the term ’aerogel’ is used across a variety of products, but not all with the same thermal value.

 

What I bought were Spacetherm A1 pads (I'd call them sheets, but they are pads on the invoice). I had a lot of trouble getting consistent advice on what is what. Proctor are fairly helpful, but they still take for granted that products they work with everyday will make sense to DIY'ers like us!

 

It came in an "8x4" sheet, rolled up. It's reasonably flexible, but they encourage the use of separate pieces on my steel column rather than wrapping it round the corner and I think that was good advice. It would follow a curve for sure, but you wouldn't want to wrap it around 2 sides of an object.

 

FYI, I paid £515 plus VAT for 2 full sheets. The carriage was £40+VAT (included in that £515).

 

I'd post you a small offcut if you want to see it before you fork out?

I think the fibre matrix is made from polyester.

So think of it as a very dusty blanket that has been gathering dirt at your grandmother's for the last 60 years.

Then think about what is sticking to it, and why it does not bend tight to make a good hospital corner.
