How to Stop the Heat From Coming Through a Patio Door
Prevent heat from penetrating a glass patio door by installing a window covering. (Waterfront Patio image by wabkmiami from

Heat radiates through the window glass and around the framing of a patio door. A properly installed door will prevent the heat or cold from entering the home around the framework. This does not stop the penetration of heat into the home through the glass panels. A protective covering is needed over the glass to help maintain a constant temperature inside the home. Promote a green environment by using window coverings made from bamboo which is a fast-growing cellulose plant. Avoid fabrics with toxic treatment such as permanent-press, vinyl, synthetics and bleached cotton.

  1. 1

    Measure the dimensions of the glass panel or panels in each patio door. Wash the surface of the glass thoroughly to remove any oil, dirt and other residue. Let the surface dry completely before application of the tinted window film.

  2. 2

    Cut the tinted window film to the exact measurements of each glass panel. Begin installing the tinted window film by laying the top edge along the glass. Slowly press the tinted window film in place making sure to smooth out any air bubbles. Repeat the process with each glass panel. The tinted window film helps reflect the light from the window and adds a shade quality to the room. This helps keep the heat from the room without having the curtains closed continually.

  3. 3

    Install the curtain rod or bamboo curtain holders according to the installation instructions.

  4. 4

    Hang the bamboo curtains from the curtain rod or insert them into the curtain holders. The closer the curtain is hung by the glass, the better the insulation process will work.

  5. 5

    Keep the bamboo curtains closed during the day to prevent the heat from penetrating into the room. Open the curtains at night to help circulate cool air throughout the house.

Tips and warnings

  • Cloth curtains, especially those that are thermal-lined/insulated, are the best insulators for heat blocking in the summer. Blinds are not as effective.
