I have used Wallpaper for Windows in numerous locations throughout the house. We have some interior French doors where I have applied the product for privacy. I've also used it on our back door, and on several sliders. The product was on the sliders for about 10 years until we had the doors replaced. At that time, I again ordered Wallpaper for Windows for the new doors. The product is very easy to apply, the vinyl is of high quality and it looks great. I highly recommend this product if you are seeking to dress up plain windows or doors, or if you want to increase privacy, or both!
