A device designed to prevent air leaks at the base of a door, typically sold by the retailer Target, effectively seals the gap between the door and the floor. This barrier against drafts can be a simple tube of fabric filled with sand, rice, or other insulating materials, or a more complex design incorporating rubber seals and adhesive backing. An example would be a weighted fabric tube placed against the threshold to block incoming air.
Reducing airflow beneath a door improves energy efficiency by minimizing heat loss during colder months and preventing cooled air from escaping during warmer months. This can lead to lower energy bills and a more comfortable indoor environment. Historically, draft excluders have been essential household items, evolving from rudimentary methods like rolled-up rugs to the diverse range of commercially available products found today. Their continued relevance underscores the persistent need for simple, effective solutions for improving home insulation.
