This silicone draft sealer measures 2 mm in thickness and 2 in. in width, fitting gaps ranging from 0 to 1 in. to create a tight barrier between indoor and outdoor spaces. The upgraded acrylic adhesive bonds securely to most common household surfaces including marble, tile, metal, glass, wood and plastic, leaves no residual damage after removal, and regains full adhesion once fully dried after exposure to water for repeated applications. It effectively blocks unwanted wind, rain, dust and external noise, prevents conditioned indoor air from leaking out to cut down unnecessary energy consumption, and cushions door impacts to reduce harsh closing noises. No specialized tools are required for installation, users only need to clean and dry the target surface, peel off the protective film, cut the strip to desired length and press firmly into place. It works for all types of doors and windows in bedrooms, kitchens, bathrooms and offices, and resists corrosion and aging for long term use. Material: Composite.
