Product Description
The Difei EPC Intelligent Dynamic Switchable Film (Self-Adhesive Version) adopts exclusive EPC electrochromic core technology and can be directly applied to existing glass surfaces. The product regulates crystal arrangement states through electronic control: it appears in a dark state for shading and privacy when powered off, and quickly returns to high transparency when powered on. Perfectly replacing traditional curtains, the product maintains a clean architectural appearance while balancing large-area natural lighting, privacy protection, and heat insulation with energy saving, effectively solving the pain points of excessive summer heat and winter cold in large-format glass spaces. To meet the refined light control needs of different spaces, the product is divided into two core models: Low-Transmission and High-Transmission. The Low-Transmission model (visible light transmittance 0.3% to 12%) is specially designed for bedroom floor-to-ceiling windows, private meeting rooms, and west-facing areas with strong sunlight, effectively blocking harsh light and visual interference. Meanwhile, the High-Transmission model (visible light transmittance 0.7% to 35%) is better suited for large flat-roof living rooms, sunrooms, and open office partitions, achieving flexible dimming within a compliant and safe field of view while maximizing natural lighting and transparency.

Process Description
To address common construction pain points in architectural projects such as ultra-wide floor-to-ceiling windows, large-span skylights, or large-scale office partitions (where a single glass width exceeds 1.5 meters), Difei provides professional seam-matching process product support. Through scientific seam arrangement, it perfectly breaks through size limitations, ensuring system functional stability while strongly guaranteeing the smooth delivery of major commercial and high-end residential projects.
Diverse application scenarios
High-end residential and home spaces: high-rise flat-roof floor-to-ceiling windows, villas and townhouses, standalone sunrooms, and glass roof surfaces. Commercial offices and public buildings: office building business partitions, conference room glass walls, and retrofitting projects for existing architectural doors and windows (eliminating the high costs and schedule impacts of large-scale glass replacement).
Convenient Delivery and Installation
Supports precise on-demand customization. Upon arrival, the product can be quickly applied with lightweight and high-efficiency installation, meeting the high-standard delivery requirements of contractors and commercial property owners.
