Where can i buy window tint/film for a house window?

Question

like static cling film or adhesive film for a house window to reduce light intensity

Answer 1

please dont do it yourself youll regrete it. Theres a reason tint film isnt widely availible.  

Answer 2

You can get the static cling auto window tint in the automotive section at most retail stores. This works for home windows as well. I work nights and sleep days, so I need it to be dark in my bedroom. I put the dark limo tint film on the windows  and it works great. It is easily removable as well.
