Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the screening attentuation report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the ULTRA performance class, the focus is on MAXIMUM. Only highly developed shielding materials create our metrological requirements for the SFERICS® ultra classification. When every single dB counts!

Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the umbrella report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the PRO performance class, the focus is on HIGH. Purely highly developed shielding materials create our technical requirement for a SFERICS® pro classification. When above-average shielding is the goal!

Shielding Underlay Membrane SAFEBUILD® U230 for Outdoor and Indoor Use in Roofs, Facades, and Drywall. This underlay against electromagnetic smog (HF + LF) is among our highest shielding professional products. Shielding efficiency over 99,999999999% (111 dB). Width 90 cm. Effective against 5G!
The SAFEBUILD® U230 is a highly advanced underlay membrane specifically designed for maximum protection against electromagnetic fields. The shielding material consists of a four-layer membrane structure, including a micro-perforated aluminium foil. With 200.000 tiny holes per square meter, this shielding underlay membrane is highly breathable and highly permeable to water vapour while simultaneously providing an impressive shielding attenuation value of 111 dB. This unique micro-perforation was a key component in developing this innovative shielding technology and does not affect the shielding attenuation, meaning the electromagnetic shielding remains effective.
Unusually for this type of product, there is a deviation from the standard width of 150 cm. SAFEBUILD® U230 has a width of 90 cm, allowing the shielding underlay membrane to be used worldwide without high bulky item shipping costs. For the customer, this means faster and significantly cheaper transport.
In addition to the extraordinarily high shielding of RF high-frequency electromagnetic fields (HF), the underlay is also very suitable for shielding low-frequency electric alternating fields (LF) (grounding).
As SAFEBUILD® U230 is produced locally in our region, special productions with a width of 150 cm and jumbo rolls from 100 linear meters are available on request.
Application and Capabilities of SAFEBUILD® U230
EMF High Performance for Indoor and Outdoor Use
SAFEBUILD® U230 excels with its universal applicability for both outdoor and indoor use, including roofs, facades, and drywall.
Due to these versatile applications, the membrane optimises the windproofing of the construction and stops rain. The aluminium foil protects against the ingress of warm air in summer and cold air in winter.
Grounding of SAFEBUILD® U230
This product with an electrically conductive surface must be grounded by integrating it into the functional equipotential bonding (FEB). See the grounding product category for suitable components. For this product, the aluminium side must be grounded, i.e., our grounding tape GSX must be adhered to the silver side!
Technical Data for SAFEBUILD® U230 Underlay Membrane
Shielding Attenuation: 111 dB
Unless otherwise specified, the given dB values apply at 1 GHz. Measurements from 600 MHz to 40 GHz according to ASTM D4935-10 or IEEE Std 299-2006 standards.
Width: 90 cm | 150 cm available on request
Length: Sold by the meter / 50 m roll | 100 m roll available on request
Field Type: HF (High-frequency electromagnetic fields), LF (Low-frequency electric alternating fields)
Installation of Shielding Underlay SAFEBUILD® U230
The professional application of a
1) water vapor diffusible 2) waterproof 3) reflective membrane
for roofs, facades and drywall construction is sufficiently described in the literature and is well known to your craftsman, planner and architect. For the best shielding result, the membranes must always be applied overlapping, without a gap, and holes for fastening must be kept as small as possible.
To protect against corrosion, the aluminium side must always be laid towards the inside of the house and the brand imprint should be visible.
Declaration of performance according to EN 13859-1:2010; EN 13859-2:2010
This product has multiple variants. The options may be chosen on the product page
Order quantity, revocation of the order and small quantity surcharge
If the netting has been cut in pieces of 1.0 running meter as requested by the customer, it is not possible to cancel or revoke the order.For this reason, it is possible to request a free sample of the shielding underlay membrane. By ordering pre-finished products, waiving the statutory right to return goods is accepted.
Small quantity surcharges for small quantities up to 3 running meters have been removed for reasons of transparency and fairness. The individual linear meter therefore always has the same price or price advantage for larger quantities. To refinance expenses and packaging, we charge a flat rate of € 6,90 per cut.
Test Report & Expert Opinion on Shielding Attenuation up to 40 GHz
Many years ago, YSHIELD invested in its own professional EMC laboratory. Here, not only are test reports generated, but each batch is also tested daily. In addition, YSHIELD has all products reviewed by an independent, renowned expert. Double-checked for double security.
