small conservatory DIY cavity wall insulation

[homelyn]

Hi
I am trying to find a UK supplier of expanded polystyrene beads or pearlite beads that I can pour into a small cavity wall round a small conservatory.

I have the wooden shelf off at present and thought it would be a good idea to put some insulation in, but can't find anyone to sell me some. they all want to install.

cheers

Eric

Thanks for the two sites, looks like I may be able to use one of them.

Thanks again
