About Us

A Leading Brand In High-End Narrow-Frame Window And Door, Pioneering Innovation To Shape The Future

SLEEK follows the architectural design philosophy of "LESS IS MORE" proposed by the modernist architectural master, Ludwig Mies van der Rohe. "Less is more" is not merely a trend, but rather a core concept. SLEEK advocates simplicity; we employ technological methods to streamline doors and windows, refining each design element into a more concise and pure expression.

Why Choose Ultra-Slim?

Ultra-slim windows and doors have surged in popularity, merging cutting-edge design with unmatched functionality. Here’s why discerning clients and architects are making them a centerpiece of contemporary projects

Uncompromised Natural Light & Panoramic Views

· Breathtaking Visual Freedom: Ultra-thin frames maximize glass surface area, dissolving the boundary between indoors and outdoors. The result? Sunlit interiors and unobstructed vistas, whether in a mountain retreat or a high-rise apartment.

Architectural Sophistication

· Design Versatility: Ultra-thin profiles complement modern, industrial, or avant-garde aesthetics, elevating a building's exterior from ordinary to iconic.

Energy Efficiency, Discreetly Engineered

· Climate Control Mastery: Advanced thermal breaks and triple-pane glazing lock in warmth during winter and deflect summer heat, slashing energy costs by up to 30%.

Seamless Indoor-Outdoor Living

· Fluid Space Transformation: Ultra-slim sliding or folding doors erase thresholds, merging living rooms with gardens, patios, or balconies—perfect for entertaining or serene relaxation.
