I have a house made of shipping containers. Recently, all the house renovation works are done, and the only thing remaining is the solar panel installation. It will be over in a week. Now I'm thinking about the window treatment. I'm a bit confused about selecting the right material. The method I chose for the insulation is the spray foam method, and it is one of the best. So I don't need any insulation materials for the window. I'm looking for window blinds that can be used for shipping containers, and it should be water-resistant. Which is the ideal material that can I use for the shipping container home?
