The key features of this entry door are its professional sound insulation and energy-saving performance. Unlike ordinary entry doors, it adopts a 3-layer EPDM rubber sealing strip design, which is installed on the door frame, door panel, and bottom of the door to form a full-sealed structure, eliminating gaps that cause noise and air leakage. The high-density polyurethane foam filling has a closed-cell structure, which not only provides excellent sound absorption performance but also has good thermal insulation effect, reducing indoor and outdoor heat exchange. The cold-rolled steel plate shell is sturdy and durable, while the laminated wood grain film surface has a realistic wood texture and is easy to clean, matching various residential decoration styles. Equipped with a B-grade lock cylinder, it provides basic anti-theft performance, meeting the daily security needs of ordinary households. The E0 grade environmental protection certification ensures that no harmful substances are released, making it safe for families with children, pregnant women, or allergy sufferers.
The standard size of the door is 900mm in width and 2100mm in height, with customizable widths ranging from 800-1100mm and heights ranging from 2000-2200mm to fit different doorway sizes. The door panel is made of 0.6mm thick cold-rolled steel, which is sturdy and corrosion-resistant. The polyurethane foam filling has a density of 40kg/㎥, ensuring stable sound insulation and thermal insulation performance. The sound insulation coefficient reaches 48dB, which can block 95% of outdoor noise such as traffic, airplane takeoffs, and school bell sounds, creating a quiet indoor environment comparable to a library. The energy-saving rating is national Class 1, with a thermal conductivity of 0.024W/(m·K), which can reduce indoor heating costs in winter and cooling costs in summer. The 3-layer EPDM rubber sealing strip is resistant to high and low temperatures, with a service life of over 10 years. The laminated wood grain film surface has a hardness of 2H, resisting daily scratches and fading. The B-grade copper lock cylinder has a service life of over 80,000 unlock cycles, and the door is equipped with 2 stainless steel lock bolts with a diameter of 14mm.
This soundproof energy-saving entry door is widely used in residential scenarios with high noise pollution or high energy consumption, including urban households near busy roads, airports, railway stations, schools, and hospitals. In households near airports or highways, its 48dB sound insulation performance can create a quiet living environment, improving sleep quality and work efficiency for occupants. In northern regions with cold winters or southern regions with hot summers, its Class 1 energy-saving rating can significantly reduce heating and cooling costs, bringing long-term economic benefits. For families with children or elderly members, its E0 grade environmental protection certification ensures a healthy indoor air quality, avoiding the harm of harmful substances. Additionally, its multiple opening direction options make it suitable for various residential doorway designs, including inward opening and outward opening. The affordable price also makes it a cost-effective choice for old community renovation projects, helping residents improve living comfort without a large investment.
