Shielding cotton NATURELL ARBOR FR™
Sustainable shielding fabric with certified flame retardancy
Innovative, sustainable shielding fabric against electromagnetic radiation (EMF) with certified flame retardancy in accordance with EU standard EN 13773 (fire protection class 5.3).
A home is more than just four walls – it is a place of peace, retreat, and security.
Swiss Shield® NATURELL ARBOR FR™ was developed precisely for this purpose: to provide noticeable protection for living spaces while maintaining a natural, light atmosphere.
The high-quality shielding fabric reduces Wi-Fi, mobile phone, and 5G radiation without weighing down or darkening the room. Its gentle transparency, pleasant textile feel, and certified class 5.3 fire protection give you peace of mind – day after day.
For everyone who wants to live consciously and combine safety, sustainability, and well-being.
Ecological high-tech fabric
The fabric is made from LENZING™ Lyocell FR™ fibers, which are sourced from certified, renewable wood. The environmentally friendly production process is carried out under strict ecological standards and supports a sustainable lifestyle. The fibers used retain their flame-retardant properties permanently, even when exposed to heat or chemical stress.
Unique worldwide fire protection in accordance with EU stand
NATURELL ARBOR FR™ is the world’s first shielding fabric to achieve fire protection class 5.3 in accordance with EU standard EN 13773. It therefore meets the highest requirements for fire and flame protection and is ideal for safety-related applications such as:
- Hospitals
- Nursing and retirement homes
- Public buildings
- Workwear and protective clothing
Despite the high safety standards, the fabric remains lightweight, semi-transparent, and decorative.
Effective protection against electromagnetic radiation (EMF)
Thanks to an innovative yarn structure made from Lenzing™ Lyocell FR™, combined with an ultra-fine, silver-plated copper thread (0.02 mm), the fabric offers excellent shielding performance against high-frequency radiation (e.g., Wi-Fi, Bluetooth, GSM). The surface is also non-conductive (PES-coated).
Versatile & durable
NATURELL ARBOR FR™ is ideal for:
- Curtains and drapes
- Room dividers and canopies
- Furniture and contract textiles
- Functional decoration in sensitive areas
Its high robustness ensures a long service life and reduces the need for replacement materials – a clear advantage for sustainable interior design concepts.
