Innovative design: Soft and hard compound TPE construction provides silent door operation. The hard TPE sealing part resists deformation and degumming, while the soft TPE adhesive part offers flexibility for use in a variety of environments. Effortless installation: Suitable for narrow tracks with a tearoff bottom protrusion. Compatible with or without window screens. Adapts to different gap widths, making it versatile for various window types. Customisable fit: Tearoff design allows thinning for a precise, fit. Once adjusted, sliding windows open and close without obstruction, ensuring smooth operation. Triplelayer sealing: Effectively seals windows to prevent leaks, block wind, reduce noise, and keep dust out. Provides insulation for a more comfortable living space. Use scenario 1: Install on drafty living room or bedroom windows to reduce cold air intrusion and improve indoor comfort in winter, while maintaining smooth window operation. Use scenario 2: Apply to windows near busy streets or dusty environments to lessen noise and dust ingress without compromising window functionality or screen compatibility. Use scenario 3: Retrofit older or variably sized windows with irregular gaps; use the tearoff thinning feature to achieve a precise fit that keeps out drafts while allowing easy opening and closing.
