Help required for bank diffuser

I have been given by a friend, for my new studio, an old nice bank, called "ALADINO BANK WINDOW LIGHT 150". I believe that this item is not produced anymore, and it's very hard to find spare parts.
this bank is quite big: 150x110 cm, which is 59 x 43 Inches.
The light source is a continuous light: 2 quartz halogen lamps, 620 Watts each.
The issue is that this bank is missing the external white diffuser tissue. How can I replace this diffuser? Would an ordinary tissue, like an old bed cotton sheet do?
Thanks

Check the local fabric stores.

In the US it's called rip-stop nylon.
White.

I wouldn't use anything from a fabric store as you can never know what sort of colour cast it's going to give you - I find that a lot of fabrics manufactured to be white tend to have a blue or magenta cast.

Get some proper, colour-neutral, high-temperature diffusion from Lee or Rosco - something like Grid Cloth or Quiet Frost would be suitable. It won't be cheap but it will probably still be cheaper than buying a new one from the manufacturer would have been.

Paul Buff suggests white 200D pack cloth from Rockywoods for diffusion

He suggests the 420D because it is heavier for a bounce type situation.

Curtis, do you think this could do? It has the perfect size and it's very cheap:

Thanks for the hint. I found a seller here in Rome that seems to have this stuff in his catalog. Only, I suspect that is going to be really expensive, as the tissue they sell is 7 meters long, and this company is specialized in movies equipment...I am not sure about spending a lot on this, as this bank is too big for my studio, and I normally use flash lights. Anyway I'll call them tomorrow to find out.

Thanks. This company ships world wide too, but the tissue is too small: 60 inches, when the bank is 59.

60 inches X any length you want

if the bank is 59" X 43"... Why can't you get a piece that is 60" X 44" and have a 1/2 hem all the way around?

If that won't work use the 60" wide material for the 43" side and purchase any length you think you need for the 60" side

Thanks Kacey. I didn't understand that it comes in any lenght.
