Shielding reinforcement fabric ARM40 | RF screening attenuation against electrosmog up to 23 dB | Under plaster and for laying. 100 cm width.

ARM40 is a shielding reinforcement fabric. The plaster base is a glass fibre fabric with interwoven stainless steel threads. With this shielding mesh, laid in the thermal insulation composite system, a basic shielding against RF of up to 23 dB is achieved. Electrically conductive surface for grounding LF. Width 100 cm.

ARM40 reinforcement fabric is a non-slip and dimensionally stable glass mesh fabric for large-area screening of high-frequency electromagnetic fields (HF) and low-frequency alternating electric fields (LF). We are replacing our previous shielding reinforcement fabric with this ARM40, as it is equivalent in terms of shielding effectiveness, but the price/performance ratio is much more attractive.

ARM40 can be used as a reinforcement fabric in the exterior area in the thermal insulation composite system (Therm/ispotherm ETIC systems) under plaster. It is also well suited for interior use under plaster. It is also suitable for loose laying in roof areas, under facades, under floor coverings, under wooden boarding in roof and wall areas, etc.

Processing of ARM40 shielding reinforcement fabric

The processing of the shielding mesh is identical with the application of conventional glass fibre fabric. Needs to be pressed non-porously and wrinkle-free into the freshly spread reinforcing mass, then levelled out.. The mesh needs to lie in the upper third of the reinforcing mass and be completely covered by it. The overlapping between the panels needs to be 10cm. The overlapping needs to be ensured at corners of a building, too. Building openings (windows, doors) require a diagonal reinforcement with fabric strips. Has the mesh been cut in (e.g. in the area of scaffolding anchors), an additional fabric strip needs to be placed above the cut. For grounding, the stainless steel perforated tape ELB must be screwed securely onto the underground across/with all panels.

Shielding and grounding of ARM40

• This product shields high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Expert reports ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006 (view screening attentuation report).
• This product with an electrically conductive surface shields low-frequency alternating electric fields (LF). For this purpose a grounding is necessary, i.e. an integration into the functional-equipotential bonding (FEB), please find suitable grounding accessories under “Grounding”.

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 fleece. 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.
