Question for Floyd Blue

Hi Floyd,

I was doing some research on boundary layer fans and came across your setup (Picture attached). I was wondering what kind of foam is being used and where did you get it?

Thanks for your help,
David

Hi David,
The foam is a closed cell type from an online source, it is a non gassing type and quite stiff and chemical resistant.
Private message me and I will give you the address.
This is not cheap foam, it is pretty expensive. I had to buy a large piece when I bought it, but I think they do offer a smaller piece.
