Product catalog summary

Introduction
Mermet, founded in 1951, specializes in sunscreen fabrics that enhance comfort and functionality in various spaces. Their products are designed to filter sunlight, improve acoustics, reduce glare, and enhance privacy, focusing on user needs.

Product Features
The Pentagrama fabric line offers a balance of transparency and light control with an elegant stripy pattern, suitable for classic rooms. It is available in light colors to maintain comfortable temperatures and drapes smoothly on roller blinds.

Technical Specifications
The fabric consists of 24% polyester and 76% PVC, with a width of 300 cm and a roll length of 30 lm. It has a surface mass of 388 g/m² and a thickness of 0.61 mm, featuring high breaking and tear strength in both warp and weft directions.

Fire and Safety Standards
The fabric complies with fire safety standards such as Class 1 EN 13773 in the EU and FR NFPA 701 in the US.

Processing and Maintenance
Recommended cutting methods include cold knife and ultrasonic. Welding can be performed thermally or with high frequency. Cleaning involves dust removal and washing with soapy water.

Thermal and Visual Properties
The fabric's solar and light control properties are tested according to EN 14501:2021 and ISO 52022-3:2017 standards, offering good thermal performance with low solar factor values for effective energy management.

Acoustic Properties
Sound absorption is measured according to ISO 354:2003 and ISO 10534-2:2023, indicating potential for acoustic improvement.

Handling and Care Instructions
To prevent damage, large fabric widths should be rolled on a tube during assembly. Fabrics with a white acrylic coating should be handled on clean surfaces, and cotton gloves are recommended for metallised fabrics.

Warranty
Mermet offers a five-year warranty on most solar shading fabrics, valid under normal use and maintenance conditions as specified in their technical documentation.

Handling Recommendations
To facilitate handling and avoid marks, roll panels on a tube during production. Handle fabrics with a white acrylic coating on a clean, dust-free surface. Use gloves for metallic coatings to avoid fingerprints.

Storage Conditions
Store fabrics in original packaging, using individual cardboard tubes. Rolls should be stored horizontally in stable temperature and humidity conditions. Avoid high temperatures to prevent color fading. Use transportation aids and avoid lifting rolls by the ends.

Maintenance Guidelines
Handle fabrics with care using clean, dry hands, and gloves are recommended. Avoid vigorous scrubbing, solvents, or abrasive substances. Raise blinds when cleaning windows to prevent chemical exposure.
