Home weatherization is an easy and affordable do-it-yourself project that can be done all year round to help block drafts and air leaks that lead to high heating and cooling costs. Cracks and gaps around windows and doors can cause drafts to come into your home, leading to high heating and cooling costs. Self-Adhesive Duck Brand Heavy-Duty Weatherstrip Seals are made with durable and flexible material, allowing them to stand up against extreme temperatures that cause other seals to freeze or crack. They are a great solution for replacing old or worn door and window seals, forming a barrier against the outdoor air, as well as dust, pollen and insects during the warmer months. Use together with other Duck Brand weatherization products to make your home more comfortable and energy efficient all year long.
