The L1-500 Series stands as a pivotal offering within LEAPKA’s comprehensive portfolio of solar control textiles, engineered specifically for applications where a 5% openness factor delivers the optimal balance of glare reduction, outward visibility, and solar heat management. This collection of Sunscreen fabrics is defined by a consistent architectural-grade specification, providing a versatile foundation across a deliberately curated spectrum of colors to meet diverse aesthetic and functional project requirements.

Series Composition & Product Array

The series is architected around a core technical platform, expressed through multiple colorways:

Neutral Foundations: L1-501 White (pure white), L1-505 Light Grey, L1-506 Dark Grey, and L1-509 Black provide solid, monochromatic options for modern design statements.

Warm & Subtle Blends: L1-502 White/Beige and L1-507 Black/Brown introduce warmth and sophisticated tonal variation.

Contemporary Contrasts: L1-503 White/Grey, L1-508 Black/Grey, and L1-512 Black/White offer dynamic two-tone visual textures.

Cool & Vibrant Accents: L1-510 White/Blue delivers a distinctive color highlight for specialized interior schemes.

Fundamental Material & Structural Engineering

Every variant in the L1-500 series is constructed to identical, precise standards:

Core Composite: A 30% high-tenacity polyester / 70% PVC coating matrix. This proven formulation ensures long-term dimensional stability, tear resistance, and protection against environmental degradation, forming the backbone of a durable Roller blinds Fabrics solution.

Areal Density: 420 g/m² (± 5%). This weight specification is calibrated to provide sufficient substance for smooth, stable operation in roller systems while remaining compatible with a wide range of standard and motorized mechanisms.

Standard Formats: Fabricated in production widths of 200 cm (78”), 250 cm (98”), and 300 cm (118”), supplied on 35-meter rolls to accommodate projects of varying scale efficiently.

Optical & Functional Performance Metrics

The series’ defining characteristic is its calibrated 5% openness, which governs its performance profile:

Openness Factor: 5% (± 0.5%). This precise specification is the result of intentional engineering. It effectively scatters and filters intense direct sunlight, significantly reducing screen glare and visual discomfort, while maintaining a clear connection to the exterior environment and permitting the diffusion of soft, natural light.

Weave Architecture: A 46 x 44 thread count, achieved with 0.32mm diameter yarns, creates the fine, uniform plain weave. This tight construction is responsible for the fabric’s consistent appearance, hand-feel, and its ability to reliably maintain the target openness percentage across its entire surface.

Profile: A thickness of 0.60 mm (± 5%) contributes to a clean, compact roll in cassette housings and consistent handling during fabrication.

Quality Assurance & Compliance

Manufactured under controlled conditions, the L1-500 series adheres to international standards relevant to architectural interiors, including fire safety (Class B rating) and colorfastness, ensuring its suitability for commercial and residential specifications as a reliable category of Sunscreen fabrics.
