EXTSUD 100x5cm Under Door Draft Stopper 🏠
Description:
This under-door seal keeps draughts, noise and insects at bay while helping to maintain room temperature and reduce energy use. This door draft stopper is simple to fit to most flat-bottom doors and works well in bathrooms, hallways and living rooms.
Key Points
The strip features a compact profile that fits gaps from 0 to 28 mm and is designed to sit beneath the door without obstructing movement. It combines sound reduction with thermal blocking, so rooms stay quieter and warmer according to the manufacturer. Installation is fast and tool-free, with a strong adhesive backing that adheres to painted and unpainted surfaces. 🛠️
Durability is a focus thanks to a flexible, all-in-one silicone body that resists deformation and keeps its shape after repeated door use. The surface is smooth to avoid scuffing floors and the product is made from non-toxic silicone with uniform colouring. For wet areas the thickened adhesive backing offers water resistance, making it suitable for bathrooms and laundry rooms. 🚿

Usage Recommendations
Fit the strip by cleaning the underside of the door first and pressing the adhesive backing firmly into place. If your door has uneven wear or a warped bottom, check the contact along the full width to ensure a continuous seal. For very high-frequency door use it may require occasional reattachment as adhesive performance can vary with surface texture.
The form and flexibility mean it glides with most floor types without catching, but consider trimming to length carefully to preserve the adhesive edge. Also note that the product is intended for flat-bottom doors and may not perform as well on heavily profiled or thresholded doors, according to the manufacturer. 🔧
Positive Aspects
The three-layer construction contributes to a noticeable reduction in transmitted sound, helping to dampen street noise and household bustle. The combination of thermal blocking and insect exclusion can help lower heating demands in colder months and reduce unwanted drafts. Three-layer design and waterproof backing are particularly useful features for rooms exposed to moisture or external temperature changes.
