Door Draft Blocker Adjustable Under Door Seal Strip for 1.4-2.2 Inch Thick Doors Insulated Foam Noise Reducer Energy Saver Indoor Outdoor | Thomler

Keep Every Room Cozy Year-Round Without Sky-High Energy Bills

Imagine walking barefoot through your home in January without that icy draft sneaking under the door. This adjustable under-door seal creates an airtight barrier that stops cold air, dust, street noise, and even unwelcome insects from slipping into your space. The soft foam core compresses gently against any floor surface—hardwood, tile, carpet—so you get a snug fit that stays put every time you open or close the door. Perfect for bedrooms, home offices, garages, and front entryways, it works on doors between 1.4 and 2.2 inches thick and stretches to fit widths up to 36.6 inches. The durable polyester shell resists wear and tear, season after season, so you can enjoy lower heating and cooling costs without constant replacements.

• Silences Outside Noise: Dense foam cushioning muffles hallway chatter, street traffic, and neighbor sounds for peaceful sleep and focused work.
• No-Tool Installation: Slide the stopper under your door in seconds—no screws, adhesive, or measuring required—and move it to another door just as easily.
