For professionals specifying solar control solutions, precise and comparable data is fundamental. This article serves as a consolidated technical dossier for the LEAPKA L1-500 series, detailing the unified engineering and diverse aesthetic expressions within this 5% openness fabric family. Understanding these specifications is the first step in selecting the optimal Sunscreen fabrics for any architectural shading project.

Series Identity & Product Line-Up

The L1-500 series is defined by its 5% openness factor, a specification engineered for environments requiring a balanced compromise between view-through clarity and effective solar management. The series comprises the following color variants, all sharing identical core performance attributes:

Monochromatic Portfolio: L1-501 (White), L1-505 (Light Grey), L1-506 (Dark Grey), L1-509 (Black). These provide solid, consistent backdrops for minimalist or bold design statements.

Tonal & Warm Variants: L1-502 (White/Beige), L1-507 (Black/Brown). These options introduce organic warmth and subtle visual texture.

Contrast & Graphic Designs: L1-503 (White/Grey), L1-508 (Black/Grey), L1-512 (Black/White). Designed for visual impact, these fabrics add a dynamic, architectural layer to interior spaces.

Specialty Colorway: L1-510 (White/Blue). A specific accent color for thematic or brand-aligned projects.

Unified Core Technical Specifications

Regardless of color selection, every fabric in the L1-500 series adheres to the following manufacturing standards:

Parameter Specification Implication for Performance & Application

Composition 30% Polyester Yarn / 70% PVC Coating The polyester provides tensile strength and stability; the PVC coating ensures durability, UV resistance, colorfastness, and easy cleaning.

Weight 420 g/m² (±5%) Optimized for smooth operation in roller systems, providing enough substance for wind resistance without overburdening mechanisms.

Thickness 0.60 mm (±5%) Contributes to a neat, compact roll in cassettes and consistent handling during fabrication.

Openness Factor 5% (±0.5%) The defining characteristic. Effectively diffuses sunlight to eliminate glare while preserving outward visibility and allowing soft natural light penetration.

Standard Widths 200cm (78"), 250cm (98"), 300cm (118") Caters to a vast majority of global window and glazing system standards.

Roll Length 35 meters Standard industry length for efficient logistics and project planning.

Weave & Yarn Plain Weave, 46 x 44 count, 0.32mm yarn Creates a fine, uniform surface that ensures consistent optical performance and a premium aesthetic.

Performance & Compliance Summary

The series is designed for long-term reliability. Key performance benchmarks include:

Solar Protection: Significantly reduces solar heat gain and blocks over 90% of harmful UV radiation, protecting interiors and occupants.

Fire Safety: Meets international Class B fire rating standards (e.g., EN 13501-1), making it suitable for most commercial and residential applications.

Durability: The PVC coating provides excellent resistance to moisture, mildew, and environmental pollutants, ensuring longevity with minimal maintenance.

This consistent technical foundation across all colors makes the L1-500 series a dependable and versatile category of Roller blinds Fabrics, allowing designers to prioritize aesthetic selection without compromising on known performance outcomes.
