The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

The most popular way to remove home window tint is by using a hairdryer. Most people already have one in their home, but if you don’t, you can buy one for as little as $15. All you need to do is turn the hairdryer to its hottest and highest setting and run it over the window tint for a few minutes. Then, you can easily peel it away. You may need some goo remover for any leftover adhesive, but this DIY could be free for many people.    

A common way to modernize arched windows is to install interior window treatments that allow light through the curved portion up to and let you cover the bottom portion for privacy. You can also install plantation shutters to make an arched window look more modern. From the exterior, arched windows can appear outdated if they’re coupled with ornate trim, so toning down the decor can make your window look more natural with a modern design.

You can easily and cheaply use tin foil or cardboard to black out your windows. Save a pretty penny by cutting either material to the size of your windows and taping it to the window. This is one of the easiest and most budget-friendly blackout solutions, but it definitely isn’t the most aesthetically friendly.
