3.Thermal Curtains
Thick or thermal curtains provide an excellent way to add an extra layer of insulation to your windows. Using double curtains offers a dual benefit. During the day, they allow natural light in, while at night, the thick fabric serves as an effective barrier against the cold. It’s both a practical and aesthetic solution that helps create a warm atmosphere.

4.Shutters
Shutters are a popular option in many homes. In addition to providing good thermal insulation, they enhance the security of your windows and, therefore, the safety of your home. The market offers a wide range of materials and prices for shutters.

Good to Know: You can apply one or more of these tips, or even combine all four for optimal protection.
