Product catalog summary

Introduction
Mermet specializes in high-performance sunscreen fabrics, focusing on creating comfortable environments by addressing human needs. Their products aim to filter sunlight, improve acoustics, reduce glare, and enhance privacy.

Product Features
The fabrics feature a double-sided pattern for optimal visual and thermal performance, available in three densities. They have a reflective white side for thermal comfort and a darker side for glare control, maintaining outward visibility.

Technical Specifications
Composed of 36% fiberglass and 64% PVC, the fabrics have a satin weave, available in widths of 250-320 cm and a roll length of 33 meters. They exhibit high color fastness and specific acoustic properties.

Mechanical Properties
The fabrics have high breaking strength and tear resistance, with low elongation at break, ensuring durability.

Fire Resistance
Compliant with fire safety standards like M1/B1, the fabrics are certified in Germany and classified as Class 1 in the EU, meeting standards in France and the US.

Processing and Maintenance
Fabrics can be cut and welded using various methods. Maintenance involves dust removal and cleaning with soapy water.

Thermal and Visual Properties
Tested according to EN 14501:2021 and ISO 52022-3:2017, the fabrics provide effective solar heat and light control.

Energy Transmittance and Visual Comfort
Energy transmittance (g-tot) is crucial for visual comfort, classified into five levels. ISO 52022-3:2017 determines total solar energy and light transmittance.

Emissivity
Low emissivity fabrics reduce energy consumption by trapping emitted energy, enhancing thermal comfort.

Acoustic Properties
Standards ISO 354:2003 and ISO 10534-2:2023 measure sound absorption coefficients, assessing material sound absorption potential.

Solar Properties
Key metrics include solar reflectance, transmittance, and absorptance, with a low solar factor indicating good thermal performance.

Thermal and Optical Indices
Defined by EN 14501:2021, these indices measure solar protection performance, assessing thermal and visual comfort.

Handling and Care Instructions
To prevent damage, roll panels on a tube during assembly, handle with clean hands or gloves, and store in stable conditions.

Warranty
Mermet offers a five-year warranty on most fabrics, valid under normal use and maintenance conditions.

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.

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...
