ULTIMA_ARBOR shielding fabric against RF electrosmog from radio waves (mobile phones, Wi-Fi, DECT, …) made from wood-based viscose (LENZING™ ECOVERO™). RF shielding up to 42 dB against electrosmog from radio waves. Shielding efficiency 99,99% – effective against 5G!
Even though this shielding fabric is directly comparable in measurement terms with our ULTIMA shielding fabric, it belongs to a completely new manufacturing technology. With ULTIMA_ARBOR, Swiss Shield® once again proves that they are true professionals in technical textiles. ULTIMA_ARBOR can be described as a technological step forward in the manufacture of shielding fabrics. The traditional raw materials of cotton or polyester were promptly replaced with viscose, more precisely with LENZING ECOVERO fibres, which have even been awarded the EU Ecolabel.
The viscose fibres themselves are made from the renewable raw material wood. The wood used comes from certified and controlled forestry. In this manufacturing process, emissions and water impact are around 50 percent lower than in the production of generic viscose (according to Lenzing, compared with generic viscose, Higg MSI). With this viscose fibre, the ULTIMA ARBOR shielding fabric relies on a wood-based rather than a purely synthetic raw material. Of course, high shielding against electromagnetic radiation from mobile phones, Wi-Fi, Bluetooth, etc. was not neglected in the process.
The visually appealing ULTIMA_ARBOR shielding fabric is excellently suited for curtains and room dividers. Due to the woven-in, radio wave-reflecting silver threads being insulated for protection, there is no oxidation with oxygen, and thus no discoloration of the ULTIMA_ARBOR shielding fabric over time. Therefore, the curtain or room divider made with ULTIMA_ARBOR remains unchanged in its attractive, natural ECRU-WHITE colour tone for years.
The ULTIMA_ARBOR™ shielding fabric is the luxury version of the NATURELL™ shielding fabric by Swiss-Shield®. This fabric is a semi-transparent viscose material designed to shield against high-frequency electromagnetic fields (HF) from transmission towers and private devices such as mobile phones, smartphones, Wi-Fi routers, mobile LTE internet, etc. However, it should be noted that this shielding fabric cannot be grounded. ULTIMA_ARBOR™ is electrically non-conductive, so its shielding capability is limited to the reflection of incoming radio waves.
ULTIMA_ARBOR™ shielding fabric is made from LENZING ECOVERO viscose fibres. This patented high-tech yarn is made of 82 % viscose, 17 % copper, 1 % silver, achieving high shielding attenuation values of up to 42 dB.
Applications and Capabilities of ULTIMA_ARBOR™
Ideally, due to its translucency, ULTIMA_ARBOR™ is perfect for curtains and room dividers.
The compelling properties of the ULTIMA_ARBOR shielding fabric include
- Fabric certified to OEKO-TEX® STANDARD 100 (ZH015 208475)
- High shielding attenuation for such a natural-looking fabric
- Excellent value for money
- Textile properties: Washable (dry-cleaning), sewable
- Quality rating: Very high
This product contains electrically conductive components inside, which, however, are not accessible and cannot be grounded. Therefore, individual areas do not shield against low-frequency electric alternating fields (NF). However, if this product is used to create a Faraday cage (complete shielding with six sides), no low-frequency electric alternating fields (NF) can be detected inside with a potential-free measurement.
ULTIMA_ARBOR™ Technical Specifications
- Shielding attenuation: 42 dB, double layer 54 dB
Unless otherwise specified, the dB values given apply at 1 GHz. Measurements from 600 MHz to 40 GHz according to ASTM D4935-10 or IEEE Std 299-2006 standards. - Width: 250 cm, +/- 2 cm
- Length: Sold by the metre
- Raw materials: 82 % viscose, 17 % copper, 1 % silver
- Grammage: 85 g/m²
- Dimensional stability: +/- 3 %
- Application: Curtain, Room Divider
- Type of Field: HF (High Frequency Electromagnetic Fields)
Please note: If low-frequency electric fields are also to be shielded, complementary measures with, for example, shielding paints or shielding wallpapers are necessary.
Care Instructions for ULTIMA_ARBOR™ Shielding Fabric
- DRY CLEAN ONLY
- Do NOT wash
- Do NOT iron
- Do NOT tumble dry
- Do NOT bleach
This shielding fabric ULTIMA_ARBOR CANNOT BE WASHED IN THE WASHING MACHINE because it is not equipped with slide resistance. However, dry cleaning is possible, even if, in our view, this does not suit the character of a wood-based fibre.
Order Cancellation | Request Free Test Sample
If the shielding material is customized and cut from the roll in increments of 1.0 running meters at the customer’s request, returns or cancellation of the order are not possible. Therefore, you have the option to request a free material sample – please request it BEFORE ORDERING custom-cut material!
All our shielding materials are highly advanced specialty products with outstanding performance. The resale of custom-cut shielding material of this performance class is either not possible or only possible with significant financial loss, and therefore legally falls under the exception to the right of withdrawal.
By ordering custom-cut running meters, your right of withdrawal expires; by placing the order, you accept our cancellation terms and waive your right to return.
