Greborn, a well-known door and window manufacturer, recently formally introduced a new line of high-performance sealed door and window models. It has achieved ground-breaking improvements in key functions like sound insulation, thermal insulation, and waterproofing with creative sealed structure design and premium material application, giving customers a peaceful, energy-efficient, and comfortable living environment and garnering significant industry attention.

Inadequate sealing performance is a common issue with traditional doors and windows, which causes noise intrusion, rainwater leakage, frequent indoor and outdoor heat exchange, and other issues. Greborn created a "three-layer sealing protection system" by matching multi-cavity broken bridge aluminum profiles to block heat conduction pathways, utilizing automotive-grade EPDM sealing strips with exceptional elasticity and aging resistance, and achieving close fit between profiles and glass, frame, and wall through seamless splicing and precise compression technology, thereby eliminating gap hazards from the source. The team worked for two years to address this market pain point.

The airtightness of this series of doors and windows meets Grade 8 of the GB/T 7106-2019 standard, the water tightness reaches Grade 6, and the maximum sound insulation capacity is 42 decibels, which is more than 30% more energy-efficient than regular doors and windows, according to authoritative testing. Homeowners in a Beijing street-facing community reported that following installation, indoor noise levels decreased from 68 decibels to 32 decibels, indoor temperatures rose by 7°C in the winter compared to before replacement, and air conditioning energy consumption dramatically decreased.

"Sealing performance is the core competitiveness of doors and windows, and also the key to improving residential quality," the Greborn manager stated. In addition to emphasizing the sealing effect, environmental protection is considered during the product R&D process. The recyclable materials used to make the sealing strips satisfy green building regulations. Greborn will continue to advance sealing technology innovation in the future, encourage the door and window industry to upgrade toward high performance, energy conservation, and environmental protection, and provide more families with a high-quality living environment.
