Any gate, any door have a gap between the interfaced surfaces. Otherwise it would complicate their work. Such gap is also the main reason for losses of heat during a zimny season or the cooled air in summer. It is especially actual for big buildings and industrial rooms and warehouses of the big area. A large number of gate or doors in such building leads to big material inputs on heating or conditioning.
Installation of strip sealing brushes solve this problem. These brushes serve as a fine barrier to leak of air from the room. Such sealant can prevent up to 98% of an infiltration of air. Besides, sealing brushes can prevent losses of heat of industrial furnaces, thereby improving their work.
