Door and window solutions

1. Industry overview

Doors and windows are the key components of the building envelope, which bear multiple functions such as thermal insulation, sound insulation and noise reduction, air tightness and water tightness, safety protection, and aesthetic decoration.With the advancement of the “dual-carbon” strategy, the rise of passive buildings, and the improvement of consumer requirements for living quality, the door and window industry is fully upgrading from traditional functional products to high-performance, systematic, intelligent, and customized.

According to data from the China Building Metal Structure Association, the market size of system doors and windows will exceed 120 billion yuan in 2024, with a compound annual growth rate of 15%, of which the penetration rate of energy-saving doors and windows will increase to more than 40%.In the future, system doors and windows with constant temperature, mute, safety, and intelligent control capabilities will become the mainstream.

2. Matching of core application scenarios and pain points

3. Key technologies and system solutions

1. Seamless welding technology: solve the problem of traditional splicing gaps

Technical principle: High-precision laser welding equipment is used to fan and melt the aluminum profile frame into one to achieve seamless connection at the physical level.
Core advantage：

Leap in sealing: the air tightness reaches the national standard level 1, the water tightness exceeds level 3, and the sound insulation is increased to more than 40dB.
Enhanced durability: stress concentration is eliminated and the life span is extended to more than 20 years.
Improved aesthetics: the surface is smooth without stitching marks, and it is suitable for minimalist style.
Representative company: Scott (Shandong) Aluminum Industry, with 200+ patents, automatic control of the whole industry chain.

2. Multi-climate hardware system: adapted to China's complex climate environment

HOPO ”Multi-climate door and window hardware system" solution：

Inland in the north: wind and sandproof, high air tightness, cold and brittle resistance, multi-lock point design.
Northern coast: typhoon resistance, high water tightness, corrosion resistance, differentiated surface treatment.
Inland south: super-sealed, moisture-proof and mildew-proof, with multiple locking points and a close fit.
Southern coast: wind pressure resistance, salt spray resistance, high load-bearing, mobile fan extrusion locking.

3. Constant temperature energy-saving technology: to achieve warm winter and cool summer

Fulinmen Family “Global Thermostatic Doors and Windows”：

The nano-thermal insulation coating selectively reflects infrared rays and is light-transmitting and heat-permeable.
Broken bridge structure + multi-cavity design, the K value of the heat transfer coefficient is as low as 1.8W/(㎡·K).
The indoor and outdoor temperature difference is 8℃, and the annual energy saving is more than 20%.

4. Safe delivery system: guarantee the whole process from product to installation

Yidun doors and windows “17 standard installation processes”：

The whole process of measurement → design → production → transportation → installation → acceptance is standardized.
“2H quick replacement of new windows" service, the removal of old windows and the installation of new windows are integrated.
The Digital Intelligence 4.0 factory ensures product consistency.

Fourth, the development trend of the industry

1. Systematization and integration

Doors and windows are no longer just “hole seals”, but a building system that integrates structure, sealing, thermal insulation, sound insulation, shading, ventilation, and intelligent control.
Promote the integrated design of ”doors and windows + curtain wall + shading" to improve the overall performance.

2. Intelligent upgrade

Intelligent sensing system: light sensing automatically adjusts the light transmittance of the glass (electrochromic technology).
Remote control: Control ventilation, shading, and security functions through the APP.
Health monitoring: integrated air quality sensor, linkage fresh air system.

3. Green, low-carbon and circular development

Energy-saving orientation: promote passive doors and windows to help buildings “near-zero energy consumption”.
Environmentally friendly materials：

Using recycled aluminum, the energy consumption is only 5% of that of primary aluminum.
Low-temperature curing spraying technology reduces VOCs emissions by 70%.
Closed-loop recycling: establish a recycling system for old doors and windows, and the aluminum recycling rate exceeds 95%.

4. Customization and aesthetic integration

Whole house customization: the doors and windows are unified with the interior style to achieve "unbounded design".
Artistic expression: incorporate artistic elements such as carving, color, and texture to become architectural works of art.
Minimalist trend: narrow frame, large field of view, hidden hardware, to meet the modern aesthetic.

5. Standardization and service upgrade

Promote the implementation of the "System Door and Window Installation and Delivery Standards" and standardize industry services.
Provide ”design-production-installation-maintenance" full life cycle services.
Extended warranty period: the warranty for fluorocarbon coating is 10 years, and the warranty for structure is 20 years.

V. Conclusions and recommendations

conclusion

Doors and windows have evolved from “functional components” to “the core carrier of living quality”.In the future, systematization, intelligence, greening, and customization will become the four main themes of the industry.Choosing doors and windows is essentially choosing a way of life-constant temperature, silent, safe, beautiful and sustainable.
