Empowering Green Buildings with Differentiated Competitiveness
Product Description
Modern architectural curtain walls and large glass surfaces serve as the "urban coat" of buildings, yet outdoor glare, high energy consumption, and privacy protection have long remained persistent challenges. Difei adopts exclusive EPC electrochromic core technology, perfectly encapsulating the dimming film within high-specification safety glass through a lamination process. When power is off, the polarized crystals scatter randomly to present a dark state; when powered on, they rapidly align neatly to restore a high-transparency state.
For architectural designers and developers, introducing the EPC intelligent dynamic dimming film not only allows them to stand out among homogenized projects with cutting-edge technological appeal, but also meets the rigorous standards of green buildings for low energy consumption and high comfort. For building operators, it effectively resolves rapid indoor heating and high air conditioning energy consumption caused by intense sunlight, providing a cool, energy-efficient, and private comfortable space for high-end office or residential occupants.

To more intuitively showcase the disruptive nature of this technology, we compare traditional ordinary architectural glass with architectural glass retrofitted with EPC intelligent dimming film:
Light and Visual Performance
Traditional Architectural Glass: Direct sunlight is glaring, ordinary glass cannot adjust flexibly to light, and strong glare affects indoor office or living experiences.
EPC Laminated Architectural Glass: Light and shadow can be controlled at will, soft and non-glaring under strong light, transparent and clear in dim areas, with effortless and flexible light adjustment.
Indoor Temperature Control and Energy Consumption
Traditional Architectural Glass: Direct solar radiation causes heat to accumulate heavily indoors, keeping summer air conditioning energy consumption persistently high.
EPC Laminated Architectural Glass: Features an ultra-low Solar Heat Gain Coefficient (SHGC 0.15~0.16) and exceptional thermal insulation performance, significantly reducing indoor air conditioning energy consumption while providing outstanding sun protection.
Privacy and Architectural Aesthetics
Traditional Architectural Glass: Interior spaces are completely exposed, lacking the high-end feel expected of business or private spaces.
EPC Laminated Architectural Glass: Combines ultimate privacy protection with a futuristic technological feel, blending seamlessly with high-end architectural curtain walls to showcase the extraordinary taste of modern architecture.
Diverse application scenarios
- High-End Commercial Office Buildings and Office Curtain Walls: Enhances the green energy efficiency rating and business prestige of the entire building, providing enterprises with an intelligent, comfortable, and energy-efficient working environment.
- Luxury Residences and High-End Villas: Meets the dual demands of modern residences for large-area lighting, safety protection, and absolute privacy.
- Star-Rated Hotel Lobbies and Commercial Skylights: Adapts to large-area, variable outdoor strong light environments, effectively blocking high heat and enhancing the overall comfort of visitors and guests.
- Urban Landmarks and High-End Public Buildings: Creates a fluid, modern exterior facade card that combines technological appeal with environmental performance, meeting the stringent demands of high-standard green buildings.
Convenient Delivery and Installation
Supports on-demand precision customization to perfectly match various architectural curtain walls and door/window designs, ensuring highly efficient product production and delivery. Difei empowers global partners to quickly achieve green iteration and quality upgrades for their architectural products.
