Conclusion
Mermet's fabrics offer optimal comfort and functionality, emphasizing durability, ease of maintenance, and compliance with international standards.

Solar Absorptance and Solar Factor
Low solar absorptance indicates minimal absorption. A solar factor (gtot) below 0.15 indicates good thermal performance.

Thermal and Optical Indices
EN 14501:2021 evaluates solar shading performance. ISO 52022-3:2017 provides methods for determining solar and optical data.

Emissivity
Low emissivity fabrics reduce inward radiation, aiding in energy conservation for heating and cooling.

Acoustic Properties
ISO 354:2003 and ISO 10534-2:2023 measure sound absorption, providing insights into material's sound absorption potential.

Handling and Care Instructions
Roll panels on a tube during assembly to prevent marks. Handle white acrylic-coated fabrics on clean surfaces and wear gloves for metallised fabrics. A five-year warranty covers most fabrics under normal conditions.

Storage Conditions
Store in original packaging, horizontally, in stable temperature and humidity. Avoid high temperatures (>45°C) to prevent color fading. Do not stack or lift rolls by ends.

THERMAL FACTORS ÍNDICES TÉRMICOS BASIC PRINCIPLES PRINCIPIOS BÁSICOS Solar radiation is always partially transmitted through, absorbed or reflected by the fabric. The sum of all 3 equals 100. Ts + Rs + As = 100 % of solar energy. Toda radiación solar es en parte transmitida a través del tejido, absorbida o reflejada por el tejido. La suma de las 3 es igual a 100. Ts + Rs + As = 100 % de la energía solar. Thermal and optical values, as defined in the European standard EN 14501:2021 (Blinds and Shutters, Thermal and Visual Comfort, Performance Characteristics and Classification), are used to measure...

ADVICE AND CARE INSTRUCTIONS HANDLING RECOMMENDATIONS To facilitate the handling of large widths of fabric and to avoid marks on the fabric, Mermet recommends that the panel(s) be rolled on a tube at each stage of the assembly process. Para facilitar la manipulación de tejidos de gran anchura, así como para evitar marcas, Mermet recomienda enrollar los paneles en un tubo en cada etapa de la confección. En el caso de los tejidos con un revestimiento acrílico blanco en el envés, se recomienda manipularlos en una superficie de trabajo limpia, sin polvo y seca. For fabrics with a white acrylic coating...
