Sealing brush strips are sealing materials used for doors, windows, equipment, and machinery to reduce air and moisture leakage, thereby improving indoor comfort and energy efficiency. Widely used in home renovation and construction industries, these strips indeed help save electricity. Let’s explore this topic from several aspects.
How Sealing Brush Strips Work
Sealing brush strips resemble combs and are usually made of polypropylene, polyurethane, polyester, or polyethylene. Their main purpose is to fill gaps in doors, windows, and machines, minimizing heat exchange and airflow between the indoors and outdoors. This helps maintain a stable indoor temperature and reduces energy waste and operating costs.
Energy-Saving Effects of Sealing Brush Strips
Studies show that doors and windows fitted with sealing brush strips can save up to 20% of energy in winter and 8% in summer compared to those without. The strips create an airtight barrier that blocks outside hot or cold air from entering and prevents indoor air conditioning from escaping—leading to less energy consumption to maintain a stable temperature indoors.

Installation Steps for Sealing Brush Strips
Installing sealing brush strips requires some patience and technique. The general steps include:
- Measure door/window dimensions to ensure the brush strip length matches.
- Clean the frame to ensure good adhesion.
- Cut the strip according to size and shape.
- Stick the strip onto the frame, pressing firmly for a tight fit.
Versatile Applications and Benefits
H/F aluminum alloy brushes are versatile and suitable for both industrial and household use, offering strong sealing, cleaning, and fire-retardant functions. Strip brushes, made from steel, aluminum, or plastic with bristle or wire fillings, are mainly used as covers for moving parts. They insulate, block dust, and protect machinery.
Their dense bristles form an excellent seal that resists dust, airflow, heat loss, and dirt—yet have low friction and are highly flexible, adapting to uneven surfaces without damage.
Advantages include:
- High-density cushioning
- Protective sealing without wear
- Retains shape and flexibility under pressure
Application Scope
Sealing brush strips are widely used in doors, windows, industrial machinery, and electrical appliances. In addition to sealing, they also offer dustproofing, insect prevention, and noise reduction.
In summary, installing sealing brush strips saves energy, boosts comfort, and lowers costs. For best results, choose high-quality strips to ensure effective sealing and long-term durability.
