Door seal tape, also known as draft seal or weatherstripping tape, is a self-adhesive strip used around doors to seal gaps and prevent air, dust, moisture, insects, and noise from entering or escaping a room. It helps improve indoor comfort and energy efficiency by reducing heat loss and blocking drafts, making it ideal for both residential and commercial buildings. Common types include foam tape for small gaps, rubber or EPDM tape for exterior doors due to its durability, silicone tape for waterproof sealing, and V-seal profiles for tighter fits in corners. To choose the right door seal tape, measure the size of the gap and select a material suitable for indoor or outdoor use to ensure long-lasting performance.
