Question
What is the primary purpose of door sweeps and thresholds?a) To make doors look more attractiveb) To reduce gaps under exterior doorsc) To add insulation to doorsd) To block all air circulation
Solution
The primary purpose of door sweeps and thresholds is b) To reduce gaps under exterior doors. These are installed to seal the gap between the bottom of the door and the floor. This helps in preventing drafts, keeping out pests, and also helps in reducing noise. While they may add to the aesthetic appeal of the door (option a), provide some degree of insulation (option c), and block some air circulation (option d), their main function is to reduce the gap under the door.
