Acoustic certificates for flame retardant fabrics

Decorative textiles for hotels, offices, residences and homes.

At Aznar Textil, we continue to weave solutions. We have developed smart fabrics with acoustic properties that combine safety, comfort and design for your contract and residential projects. Our decorative acoustic fabrics reduce noise and reverberation, improving acoustic comfort, rest and health for people in indoor spaces.
They have been certified by the Textile Technology Institute in accordance with the UNE-EN ISO 354:2004 standard, which guarantees rigorous measurement of sound absorption in a reverberation chamber. In addition, they have been tested under international reference standards:

• DB-HR. Basic Document. Protection against noise (αmean).
• UNE-EN ISO 11654:1998. Acoustic absorbers for use in buildings (αw).
• ASTM C423-09a. Standard test method for sound absorption (NRC, SAA).
A single textile solution that dresses up the space and improves its acoustics in hotels, offices, residences, social and health centres, homes and, in general, for contract and public spaces where the following is sought:

• Less reverberation
• More comfort
• Without sacrificing either the design or the drape of the fabric
The Acoustic range is available in multiple textile solutions: certified flame retardants, dimouts, blackouts and decorative curtains.
It allows you to create consistent projects throughout the space: same aesthetics, different features (darkness, thermal insulation and now also certified sound absorption).
