I recently had a vacation in nature and wanted to feel the same atmosphere at home. I spent some time searching for ways to realize this and came across the website https://www.tintfit.com/shop/reflective-window-film. It said that windows can be of different sizes and are suitable for moderate light penetration and darkening on the other side. I installed it in my backyard (where I have a garden) and now it's nice to sit at a chair next to it.
