Doors and windows are one of the most common sources of drafts in your home. Duck MAX Triple Draft Seal is a slide-on door bottom that blocks drafts under doors, and can also keep out dust, insects and pollen during the warmer months. It offers three layers of protection – an inner seal helps retain room temperature, an outer seal blocks drafts and bottom fins help keep out moisture and water. The Duck MAX Triple Draft Seal is easy to install: just slide it onto the bottom of the door and you’re done. Use together with other Duck Brand weatherization products to make your home more comfortable and energy efficient all year long.
