The cost of smart film for home windows can vary depending on several factors such as the size of the windows, the quality of the film, installation charges, and additional features such as remote control or tinting options.

As of my last update in January 2022, the price range for smart film typically starts from around $50 to $100 per square foot for the material alone. Installation costs can vary widely based on the complexity of the installation and the rates of the contractor, but it’s generally recommended to budget an additional 30% to 50% of the material cost for installation.

Keep in mind that these are approximate figures and prices may have changed since my last update. It’s best to contact suppliers or contractors in your area to get a more accurate quote based on your specific requirements. Prices may vary based on any advancements or changes in the smart film technology since my last update.
