Residential Window Sealant Helps Keep Wind and Water Out

A durable, flexible seal around windows and doors helps prevent water and air intrusion, and makes homes more durable and energy efficient.

DuPont™ Residential Sealant is a durable, highly flexible window sealant for use in general residential construction. It is formulated to bond well with DuPont™ Tyvek®, weather barriers, and other DuPont construction products, as well as most common building materials.
