Sealing strips are sometimes called draught excluders and are used to seal (exclude draughts) your stove or wood-burning stove. Small gaps can often appear around pipe connections, and this sealing strip is ideal for filling them. You can also use it to seal other parts of your wood-burning stove if, for example, there are gaps around doors or similar. The sealing strip is made of fiberglass thread that can withstand very high temperatures. This sealing strip is loosely woven, making it soft and flexible.
