The 9mm Draught Excluder Foam – 2–4mm Gap is a durable closed-cell PVC foam seal designed to reduce draughts, minimise heat loss, and provide effective protection against water, dust, and noise around doors and windows. Measuring 4.5mm x 9mm, it is specifically designed to seal gaps between 2mm and 4mm, helping to improve insulation and create a more energy-efficient home or workplace. Manufactured from high-quality closed-cell PVC foam, this seal forms a waterproof barrier when compressed by approximately 30%, making it ideal for applications exposed to moisture. Its rot-proof construction is resistant to heat, sunlight, and water, ensuring reliable long-term performance in both indoor and outdoor environments. Easy to fit to clean, dry surfaces, this draught excluder foam is an excellent choice for both professional installations and DIY projects where a durable, weather-resistant seal is required.
