How to insulate PVC windows yourself?

Here are our tips for insulating your windows yourself!
Use PVC window insulation film
In fact, insulating window film creates an insulating barrier and prevents cold air from entering the interior of the house . Usually the package includes shrink wrap which will be applied to the interior window frame with double-sided adhesive tape. Consider heating the film with a hair dryer to shrink it and remove wrinkles.
Cover your PVC windows with bubble wrap
Admittedly, aesthetically, this solution leaves something to be desired, but bubble wrap is still an effective way to insulate the windows in your home. Spray enough water on the inside of the clean window and place the bubble side of the film (smooth side facing you) over the wet window. Then seal the edges with tape.
Add thermal curtains to your PVC windows
Thermal curtains are equipped with a special coating that retains warm air inside during the winter period and blocks heat during the summer months. Additionally, thermal curtains block light and reduce noise. Finally, consider having your curtains completely cover your windows for better insulation in the winter .

Covered with an adhesive, the foam is easy to install and stays in place. Please note that stick-on weatherstripping can be installed year-round to provide additional insulation during the summer. However, this product may show signs of deterioration over time, but its price remains affordable.
