Key benefits Stops drafts and reduces heat/cool air loss so rooms stay warmer in winter and cooler in summer — helps lower heating and cooling costs. Blocks wind and dust to keep indoor air cleaner and more comfortable. Reduces outside noise with a PU foam core for quieter rooms and better sleep or concentration. Main features Construction: PU foam core with PE film on both sides — flexible, bendable and resistant to deformation. Surface properties: waterproof, wear- and scratch-resistant, odor-free, and safe for window frames and floors. Environmentally friendly materials that provide long service life. Function and performance Thermal sealing: forms a tight barrier around gaps in windows and doors to prevent air exchange. Acoustic damping: PU foam absorbs and blocks sound, improving sound insulation for homes and offices. Weather protection: windproof and dustproof, with good water resistance for reliable performance over time. Compatibility and sizing Designed for use on doors and windows of various styles and frame materials. Can be cut to the exact length and shape you need for tight, custom sealing. Adhesive backing: peel off the white release liner and stick directly to clean, dry surfaces for a strong bond. Easy installation (step-by-step) 1. Measure the length of the gap to be sealed. 2. Cut the seal to the required length and shape. 3. Clean and dry the surface thoroughly. 4. Remove the white paper backing and press the tape onto the frame evenly. Practical use scenarios Home windows: seal single-pane or drafty windows to reduce heat loss in winter and keep rooms cooler in summer. Exterior doors: apply around door frames to block wind, dust and insects while improving insulation. Home office or bedroom: add along window and door edges to reduce street noise and create a quieter work or sleep environment. What makes it stand out Combines thermal sealing, noise reduction and dust/wind protection in one easy-to-install tape. Durable, flexible construction resists wear and keeps its shape without leaving residue or damaging frames. Simple cut-to-fit design works for a wide range of doors and windows without special tools. Notes Ensure surfaces are clean and dry before applying for best adhesion. Cut and fit as needed; the product is adaptable to different gap sizes and frame shapes.
