01Weatherstripping

  • The first step in insulating sliding glass doors is to check the weatherstripping. Over time, weatherstripping can deteriorate, causing gaps and drafts. Replace any damaged or worn-out weatherstripping with new ones.
  • Self-adhesive weatherstripping is commonly used for sliding glass doors. Clean the track and frame thoroughly before applying the weatherstripping. Measure and cut the weatherstripping to fit the length of the door frame. Peel off the backing and press the weatherstripping firmly onto the frame.
  • Make sure the weatherstripping forms a tight seal when the door is closed. Test the door to ensure there are no gaps or leaks along the edges.

02Window Film

  • Window film is another effective method to insulate sliding glass doors. It adds an extra layer of insulation and helps to reduce heat loss or gain. There are different types of window films available, such as heat-control films, UV-blocking films, and decorative films.
  • Before applying the window film, thoroughly clean the glass surface to remove any dirt or debris. Measure the dimensions of the glass panels and cut the film accordingly, leaving a slight overlap.
  • Spray the glass with a solution of water and a few drops of liquid soap. Peel off the backing of the window film and place it onto the glass. Use a squeegee to remove any air bubbles and ensure a smooth application.
  • Trim off any excess film and use a hairdryer to gently heat the film, causing it to shrink slightly and adhere to the glass surface.
  • Window films provide insulation benefits while still allowing natural light to enter the room.

03Draft Stoppers

  • Draft stoppers are simple devices that prevent cold air from entering underneath the sliding glass door. They are placed along the bottom edge of the door to create a seal and prevent drafts.
  • You can purchase draft stoppers from a home improvement store or create your own using a long, narrow pillow or fabric tube. Measure the length of the sliding glass door and cut the draft stopper to size. Fill it with insulation material such as foam or sand.
  • Place the draft stopper along the bottom edge of the door, ensuring it forms a tight seal. The weight of the door will keep it in place. Open and close the door to test the effectiveness of the draft stopper.
