Weatherstripping is an easy way to block cold or hot air from entering the home around doors, windows and electrical plates.
Step 1: Check windows and doors for air movement and drafts Windows and doors often have gaps that allow cold or warm air to penetrate the home. It is simple to locate these drafty spots and stop up the air leaks with weatherstripping. On a windy day, run your hand in front of door and window edges to see where air transfer may be happening. You can also look for gaps where the window meets the sill or the door meets the threshold. Use your hand to feel for air movement around doors and windows.
