Door draft stopper — 93 x 5 cm felt under-door seal Why you need it Stops cold drafts, reduces noise transfer and blocks dust, insects and other outdoor elements at the door threshold. Helps maintain a comfortable indoor temperature and lowers energy use by reducing heat loss in winter and keeping cool air inside in summer. Simple, reliable protection where a gap under the door causes discomfort, noise or energy waste. What it does and how it works Acts as a sealing strip: the felt body fills the gap under the door to prevent airflow, dust and insects from passing through. Provides improved sound insulation by reducing direct noise transmission under the door. The felt construction adds thermal insulation and a soft contact surface that sits flush under the door.
