Seal Cracks in Your Windows with Caulk
Applying Caulk to Seal a Window
The smallest gap in a window can bring cold air into any room. To avoid this, consider sealing all your windows as much as possible. To do this effectively, it is advisable to use caulk. This will seal all the cracks in your windows.

Install thermal curtains on your windows
Another way to insulate your windows is to install thermal curtains. Indeed, their lining can block cold air that could enter your home. In addition, they not only limit heat loss, but also add an aesthetic touch to your home. Do not hesitate to adapt them to your interior. Also note that they effectively fulfill their role of insulation, covering all the windows.

As you can see, insulating your windows can be easy and, above all, economical. This way, you will reduce the cost of your energy bill.
