This method is particularly useful if your garage doubles as a workshop or storage area that needs to stay warmer. The plastic or tarp acts as an insulating layer, reducing airflow and keeping the interior space more comfortable.
7. Seal Side and Top Gaps With Painter’s Tape and Foam Strips
If your garage door has gaps along the sides or top, use painter’s tape and foam strips to create a temporary seal. Apply the foam strips along the edges of the door frame, pressing them tightly against the door when closed. Use painter's tape to secure the foam in place and create an airtight seal.
This quick fix can help reduce drafts entering from the door's perimeter. While not a permanent solution, it can significantly reduce airflow until more comprehensive repairs are possible.
8. Insulate the Garage Door Panels With Foam Board or Reflective Wrap
Enhancing the insulation of the garage door itself can make a noticeable difference in temperature control. Cut foam board or reflective wrap to fit inside the panels of the garage door. Secure them in place with adhesive or double-sided tape.
This added layer of insulation will help keep the cold air out and the warmth in, improving the overall energy efficiency of your garage. It's a straightforward project that can be completed with materials from your local hardware store.
