In unpredictable weather, how can buildings "breathe" freely while effectively resisting wind and rain? The answer lies in a silent "breathing guardian" standing outside the walls—rainproof louvers.With scientific structural design and rigorous craftsmanship standards, NCC’s rainproof louvers create a barrier that allows buildings to "breathe" freely without fear of wind and rain. They have become a smart choice for industrial plants, commercial spaces, and public buildings.

PART.01 Choosing a Smart Barrier: Scenarios and Parameters Are Indispensable

01 Aesthetic Requirements

Aesthetically, based on the building facade design and functional requirements, one can choose between the minimalist design of single-row blades or the enhanced protection of double-row blades. Additionally, the orientation of the blades—whether horizontally arranged (transverse) or vertically arranged (longitudinal)—should align with the overall architectural style.

02 Performance Requirements

In terms of performance, the focus lies on two core indicators: ventilation rate and rainproof grade.The ventilation rate is related to the efficiency of air exchange, while the rainproof grade directly reflects the ability to block rain under different wind speeds—both are key to ensuring a dry and clean indoor environment.Only through scientific selection can it become the "customized armor" best suited to the project.

PART.02 Breaking Four Elite Models Explained: There’s Always One for You

NCC’s rainproof louver product line currently includes four models: FYL100, FYL125, FYL140, and FYL155. Each model boasts unique features to adapt to different application scenarios.

01 FYL100 & FYL155 (Single-row Blade Configuration)

Both models feature transversely arranged blades, with louver depths of 100mm and 155mm respectively. Boasting airflow coefficients of 0.390 and 0.395, and a Class 2 airflow rating, they offer high ventilation efficiency and reliable performance—making them a trustworthy choice for numerous general applications.

02 FYL125 & FYL140 (Double-row Blade Configuration)

These two models provide flexible options for both transverse and longitudinal blade arrangements. They achieve Grade A rainproof performance under various wind speeds, delivering enhanced protection while maintaining excellent ventilation. They are ideal for scenarios requiring high-level rain resistance.

PART.03 The Cornerstone of Trusted Quality: Authoritative Certifications and Craftsmanship Excellence

Quality stems from adherence to standards and pursuit of innovation. NCC has obtained certifications from internationally renowned authoritative associations such as AMCA (U.S.) and BSRIA (U.K.). Its series of functional building louvers have undergone rigorous testing in professional laboratories. Whether it comes to noise reduction, rainproofing, or sandproofing, NCC has established a mature and self-contained solution system, with performance meeting high international standards.

Currently, NCC is continuously engaging in R&D efforts, committed to developing more models to meet the personalized and cutting-edge needs of different customers.

PART.04 Guarding Buildings with Craftsmanship, Defining Ventilation with Technology

NCC’s rainproof louvers, with their rigorous craftsmanship, verifiable performance, and globally recognized certification system, have redefined the reliability of building ventilation. Whether combating strong winds and heavy rains or optimizing energy consumption, they remain silent guardians of architectural spaces.

Choosing NCC is not just choosing a product, but embracing a commitment to quality. We welcome you to explore more possibilities in building ventilation together!
