I have a lot of cold air coming thru my front door. I plan on buying a new door this Summer, but until then I want to help cut off airflow. I purchased some stuff that peels back and sticks to the door frame. But it comes off too easily and makes a mess in time. Does anyone have a good idea or brand that I should use that is easy to use and affective? Cost is not a big issue, but I would like to do it myself. Recommendations please?
