Even though they are "minor components," sealing strips are the "key players" that determine the user experience in the aluminum alloy doors and windows' performance system. They directly impact energy efficiency, sound insulation, and service life in addition to being the primary assurance for airtightness and watertightness. Being a leading manufacturer of upscale aluminum alloy doors and windows, Greborn has always placed a high priority on sealing strip technology in its product research and development, giving customers access to the "sealing powerhouse" purchase code.

Sealing strips are extremely important. According to data, between 20% and 30% of the energy used in buildings is lost due to gaps in doors or windows. By closely fitting profiles, high-quality sealing strips can prevent hot and cold air from convecting, saving more than 30% on energy use for air conditioning. They also prevent profile friction damage, effectively block out outdoor noise and rainwater penetration, and increase the lifespan of doors and windows by five to eight years. According to Greborn's laboratory tests, products with high-quality sealing strips meet Grade 6 watertightness standards and achieve sound insulation of over 35 dB, keeping the interior dry even during periods of intense rain or wind.

PVC (polyvinyl chloride), silica gel, and EPDM (ethylene propylene diene monomer) are the three primary kinds of sealing strip materials available today. Because of its long-lasting elasticity, resistance to aging, and ability to withstand temperatures ranging from -40°C to 120°C, EPDM is the material of choice for high-end doors and windows. Greborn uses imported food-grade EPDM raw materials that are UV-resistant and maintain over 90% elasticity even after 5,000 hours of artificially accelerated aging tests. PVC is inexpensive but has a short lifespan of 1-2 years due to hardening and cracking; silica gel is better at withstanding high temperatures but has poor elasticity and tear resistance, so it is better suited for specific situations.

Customers can adhere to the "look-touch-smell-check" principle when making purchases: Look for smooth edges and flat surfaces free of bubbles; feel for soft elasticity that bounces back fast after pressing; smell for strong smells (good strips don't smell). Prioritize branded goods like Greborn and verify material and manufacturer information on product labels. Its sealing strips come with a 5-year warranty and anti-counterfeiting markings.

"The 'invisible protective net' of doors and windows is the sealing strip, and high-quality products can upgrade living experience," Greborn's technical director stated. Through bionic design, the company will keep refining strip formulas and improving sealing performance to provide customers with aluminum alloy doors and windows that are quieter, more durable, and use less energy.
