Eggcrate in UK

[bobgildolf]

Hi all
Where is all the eggcrate in UK?
Obviously we don't have plastic eggcrate, so where can we get it?
I've read that there is something similar that can be found at building material websites, but I can't find anything that resembles the stuff over in the US.
Somebody help please! I am trying to set up my dart frog viv before the winter or I will have to wait till next spring to get them.

You mean this right?



For what it's worth, I believe it goes by a different name in the UK but I can't for the life of me think of it.
