Sealing windows and doors is a quick and easy way to score points in a home inspection when selling or save on utility costs in your new home—all while doing something good for the planet. DAPtex Plus Window and Door Foam Sealant is made with CoVinyl X-9000 for better weather resistance and durability. It works well on both interior and exterior surfaces and won’t over-expand. When properly applied, it can help reduce energy costs and the damage caused by moisture or pests. It’s also ideal for sealing around ducts, pipes and vents, all of which will help you enjoy the savings that come with a draft-free home.
