Don't Be Misled Anymore! The Logic Behind Door and Window Factories' Push for 110-Series Casement Windows
When entering the home building materials market, consumers will find that 110-series casement windows have an extremely high appearance rate, which is inseparable from the vigorous promotion of door and window factories. As the source of door and window production, factories' product strategies directly affect market supply. Why has the 110-series casement window become the "flagship model" of factories? It involves multiple considerations including production, costs, and market demand. Next, we will analyze this phenomenon and explore the unique value of casement windows above the 120-series with higher performance.

Controllable Production Costs, Balancing Profit and Market Acceptance
Low Production Difficulty, Adapting to Universal Production Lines
Meeting Basic Functional Requirements, Covering Mainstream Needs
Restricted Structural Design, Struggling to Cope with Complex Scenarios
Limited Glass Configuration, Bottlenecks in Sound Insulation Performance
Insufficient Insulation Strip Width, Room for Improvement in Energy Efficiency
Wide-Body Structural Design, Unlocking High-Strength Performance
Flexible Glass Configuration, Creating an Ultimate Sound Insulation Experience
Wide Insulation Strips, Upgrading Energy Efficiency
Precise High-End Positioning, Focusing on Performance R&DAdhering to the core goal of "creating high-quality door and window products".Lingyin Group Door & Window Factory has keenly insight into the market demand for high-performance doors and windows, taking casement windows above the 120-series as the key R&D direction. Cooperating with industry institutions, the factory has repeatedly tested and optimized key links such as the profile cavity structure, the composite process of insulation strips and profiles, and the glass sealing performance of the 120-series. For example, it has improved thermal and sound insulation effects by increasing the number of cavities to 4-5 independent ones, and enhanced load-bearing capacity through reinforced design of hardware notches, continuously breaking through technical bottlenecks to ensure that product performance meets the mainstream standards of high-end casement windows in the market.
Exquisite Manufacturing, Strict Quality ControlIn the production process.Lingyin Group Door & Window Factory adopts industry-leading production equipment and technology, implementing strict control over raw material procurement, production and processing, finished product inspection and other links. For casement windows above the 120-series, the factory selects 6063-T5 aluminum alloy profiles with a silicon content of ≥0.8% (15% higher strength than ordinary profiles), ensuring the cutting precision error of profiles is ≤0.5mm through CNC double-head saws and five-axis machining centers; glass installation uses automatic gluing machines and neutral silicone structural adhesives to ensure uniform glue seam width (5-7mm) without bubbles, improving water tightness and air tightness; before leaving the factory, finished products must pass multiple tests such as simulated typhoons (wind pressure ≥500Pa), heavy rains (rainfall ≥100L/(㎡·h)), and long-term sound insulation (noise attenuation ≥35dB), ensuring each window meets high-end quality standards.

With advantages such as controllable production costs, low production difficulty, and covering mainstream needs, the 110-series casement window has become a "powerful tool" for door and window factories to open up the mid-end market. However, it has obvious limitations in structural strength, sound insulation, energy efficiency and other performances. In contrast, based on mainstream parameters, casement windows above the 120-series have achieved comprehensive performance upgrades through designs such as wide-body structures, flexible glass configurations, and wide insulation strips. They not only make up for the shortcomings of the 110-series but also meet consumers' current demand for high-quality homes, becoming an important direction for factories to explore the high-end market.
For consumers, choosing doors and windows should not only consider the initial budget but also focus on long-term living experience and usage costs. As an enterprise specializing in high-end manufacturing, Lingyin Group Door & Window Factory has transformed the performance parameters of 120-series casement windows into practical products through sophisticated R&D and strict quality control, providing an ideal choice for consumers pursuing quiet, energy-saving, and safe home life. In the future, with the upgrading of building energy efficiency standards in various regions and the improvement of consumers' quality awareness, casement windows above the 120-series are expected to gradually replace the 110-series to become the market mainstream. Meanwhile, door and window factories will continue to make efforts in optimizing the 120-series processes and reducing production costs, promoting the high-quality development of the entire door and window industry.
