design: This door bottom seal features a corrugated bottom that greatly reduces contact area with the floor, delivering low friction, no noise when opening and closing, and no damage to the floor. The doublelayer clamping edge provides a stronger grip, improving noise reduction, sound insulation, wind protection, and insect protection. PVC material: Made from soft, flexible PVC that is wearresistant and durable, it can be used for years without tearing. It is also washable and can be cleaned, dried, and reused repeatedly. One door bottom seal can address multiple concerns. Good sound insulation: The acoustic chamber protrudes on both sides of the door, and the binaural design enhances soundproofing. An additional acoustic cotton at the floor contact point provides a double layer of sound insulation. Energy conservation: The seal blocks wind and drafts from entering the room, keeping hot and cold air inside and maintaining a comfortable space. By reducing air leakage under the door, it also helps lower energy costs. Applications and scenarios Home living spaces: Use on interior and exterior doors to reduce noise from hallways, minimize drafts in living rooms or bedrooms, and protect against insects while keeping floors undamaged. Offices and meeting rooms: Install on office doors to improve quiet, privacy, and energy efficiency without requiring complex installation or replacement. Entryways and traffic areas: Ideal for doors near entrances or in kitchens where wind intrusion and insect entry are concerns, while maintaining floor integrity and longterm durability.
