Outside air enters your home through the exposed dryer vent, and that means higher heating bills in winter, higher cooling bills in summer.
Your clothes dryer is connected to a 4" diameter exhaust duct that is open to the outdoors. In the winter, cold air leaks in through the duct, through your dryer and into your house, while your heated air just pours right out!
Many common discharge vents use a flapper to try to reduce this air leakage. This very primitive technology does not provide a positive seal to stop the air leakage.
Over time, lint clogs the flapper, causing it to stay open. This is like leaving a window open! In addition, rodents and insects can enter you home through your open dryer vent.
The Battic Door brand Dryer Vent Seal will reduce unwanted air infiltration, and keep out pests, bees and rodents as well.
This Dryer Vent Seal is made of high impact ABS plastic, able to withstand both high and very low temperatures. It will mount easily on the side of your house.
The Dryer Vent Seal keeps out that outside air until dryer discharge air pushes up the floating shuttle. This allows warm air, lint, and moisture to escape from the vent. When the dryer stops, gravity makes the shuttle drop back down, keeping wind, birds, bugs and rodents outside. The top may be removed for easy cleaning.
The ABS plastic Dryer Vent Seal mounts easily over existing 4" vent pipe. The vent can be painted to match your house. Mounting screws are included.
