Not sure if this company could fabricate the width you need but, I am doing a custom install of this product to enclose an outdoor kitchen with see through vinyl for a client.
They claim they have 500 materials (assuming they would have black out fabric) to choose from and the guide system can be recessed into the wall, which is what we are doing into some massive cedar trimmed posts that support the pergola.
I have not seen the product in person yet but, we will have the install completed by Easter for our client.
