EVA Dimmable Glass: A Case Study of a Smart Partition Project in a Core Business District Commercial Complex
Project Background
Located in a prime commercial district, this project is a multi-functional commercial complex integrating offices, retail spaces, and restaurants. To enhance space utilization and create a high-end aesthetic, the developer required the office meeting rooms, exhibition halls, and retail shop partitions to possess three functions: privacy switching, light control, and security protection. Furthermore, the materials needed to be suitable for a high-temperature, high-humidity climate, while also adhering to strict cost controls. After multiple rounds of material selection and comparison, EVA laminated smart dimmable glass was ultimately chosen as the core partition material.
Material Selection: Why was EVA smart glass chosen?
The project team compared PVB smart glass and EVA smart glass, and the core reasons for ultimately choosing the latter are as follows:
1. Adaptability to high-temperature construction and operating environments.
The temperature at the project construction site often reaches above 35℃. The processing temperature of EVA film is only 115℃, far lower than the 135℃ required for PVB film, thus avoiding the failure of the PDLC liquid crystal dimming layer due to high-temperature processing. At the same time, EVA film has excellent resistance to heat and humidity, and is less prone to delamination and yellowing in high-humidity climates, ensuring long-term stability.
2. High cost-effectiveness to meet commercial project budgets.
Compared to PVB smart glass, EVA smart glass reduces costs by approximately 20%. In large-scale applications for the project, this significantly reduces material procurement costs, meeting the cost control requirements of the commercial complex.
3. Multifunctional features to meet project needs.
The selected EVA film has a 90% UV blocking rate, protecting office furniture and exhibition items from fading due to sun exposure; it also provides sound insulation, blocking noise from public areas of the shopping mall and enhancing the tranquility of office and meeting spaces; and in case of glass breakage, the fragments are firmly bonded by the EVA film, meeting the safety protection standards for commercial premises.
Project Implementation Highlights:
1. Customized Dimensions and Processing.
To meet the needs of curved partitions in conference rooms and extra-large display walls in exhibition halls, EVA dimmable glass supports large-size customization and hot bending processing up to 2m × 3.6m. This allows for seamless partitions without splicing, enhancing the overall aesthetics of the space.
2. Fast Construction and Installation.
EVA dimmable glass uses a dry lamination process, shortening the processing cycle by 30% compared to PVB dimmable glass. Combined with magnetic smart switches during on-site installation, construction efficiency is significantly improved, and the overall project duration is controlled within 15 days, perfectly meeting the schedule requirements before the opening of the complex.
3. Convenient Post-Project Maintenance.
After project completion, EVA dimmable glass only requires regular wiping and cleaning, without the need for special maintenance. For one piece of glass with minor scratches due to transportation, the contractor directly replaced the dimmable layer without replacing the entire glass panel, significantly reducing future maintenance costs.
Project Implementation Results:
1. Significantly improved spatial flexibility:
The meeting room partitions can be switched between "transparent" and "frosted" modes with a single click: the transparent state ensures ample natural light, while the frosted state creates a private environment for discussions; the exhibition hall partitions, when frosted, can be used as projection screens to display brand promotional videos, and when transparent, they showcase the exhibits inside, achieving "two uses for one wall."
2. Significant energy saving and environmental benefits:
The heat insulation performance of the EVA film reduces air conditioning energy consumption in the office area by approximately 15%, and the UV blocking function reduces exhibit maintenance costs, aligning with the green operation concept of the commercial complex.
3. Highly recognized by the market:
After the project was put into use, its intelligent and aesthetically pleasing spatial effects made it a benchmark case for intelligent partitions in commercial complexes in the core business district, attracting many companies to visit and learn from it.
Case Summary
This project, through the large-scale application of EVA dimmable glass, verified the material's suitability and superiority in high-temperature, high-humidity climates and large-scale commercial settings. Its cost-effectiveness and multi-functional features make it an ideal solution for smart partitions in commercial complexes and high-end office buildings, providing replicable practical experience for the market promotion of EVA dimmable glass.
