The DuPont Tyvek 3586M Reflex Breather Membrane Roll is designed to enhance the energy efficiency and durability of buildings. Made from high-quality, weather-resistant Tyvek material, this product offers superior air and water vapour resistance while allowing internal moisture to escape, thereby preventing condensation and related problems. Its reflective surface also aids in reducing cooling costs, making it an ideal solution for warmer climates or buildings that require a high degree of temperature control.
