VEU Approved Exhaust draft stoppers, also known as vent draft stoppers, are devices used to prevent cold air from entering through the exhaust duct of a home's heating or cooling system. Their effectiveness depends on the specific design of the draft stopper and the exhaust system that is installed in your home. Some exhaust fans cannot move sufficient air when they are restricted with air flow from a closed door.

If properly installed, an exhaust draft stopper can prevent drafts and improve energy efficiency by keeping cold air out of the duct system. This can lead to lower energy bills and reduce the workload for the heating or cooling system.

However, it is important to note that exhaust draft stoppers may need to be removed periodically for cleaning and maintenance to ensure the system is working efficiently. Also, some models may require careful installation to prevent damage or improper sealing, which could lead to leaks or even damage to the heating or cooling system.

Overall, exhaust draft stoppers can be an effective solution for reducing drafts and improving energy efficiency in homes. As with any product, it is best to research and choose a reliable and high-quality draft stopper that is compatible with your specific heating or cooling system.
