design features Corrugated bottom design reduces contact area with the floor, resulting in low friction and no noise when opening or closing the door, while protecting the floor from damage and creating a quieter, more comfortable environment. Doublelayer clamping edge provides a more solid grip, enhancing noise reduction, sound insulation, wind protection, and insect protection. Materials and durability Made of soft, flexible PVC material that is wearresistant and durable, suitable for years of repeated use without tearing. Easy to clean, wash, and dry repeatedly. Sound insulation performance Acoustic chamber protrudes from both sides of the door, and the binaural design significantly enhances soundproofing. Acoustic cotton placed at the contact with the floor adds an additional layer of insulation for improved performance. Energy efficiency Blocks wind and draughts from entering the room, keeping hot and cold air out of the door and maintaining a comfortable ambient space. By preventing air from escaping under the door, it can help reduce energy usage and lower heating and cooling costs. Use scenarios Living rooms or entryways facing outdoor exposure: minimizes drafts and reduces door noise for a quieter, more comfortable environment. Bedrooms or home offices: enhances privacy and reduces sound transmission while supporting a stable indoor temperature. Kitchens or doors near exterior openings: helps prevent insects from entering and improves overall climate control.
