| Damping
chart: |
Standard-conformant tests according to MIL-STD-285
approve the extreme screening performance of Aaronia
X-Dream®: The damping performance for pulsed
high-frequency radiation in the frequency range between 1
and 2GHz, for instance caused by cell towers, is up to
100dB (99,999.999.99%). Compared to the also shown
screening fleeces from other manufacturers, Aaronia
X-Dream® offers a one hundred times (or more) better
screening efficiency in the tested frequency range.
Furthermore, allowing grounding, it is equally efficient
against static and low-frequency electric fields such as
caused by almost any cables running through homes, various
home appliances, high-voltage lines, etc.
Even in the extremely high GHz-range at far more than
20GHz!, Aaronia X-Dream® still offers an extremely
good screening efficiency of approx. 70dB.

The various screening systems available on
the market today differ widely in both affordability and
protection efficiency. They are often far too difficult to
handle, particularly for the novice, but also for
professional users. Apart from this, they are mostly far too
expensive. Also, customers currently mostly need TWO seperate
screenings simultaneously, as most screenings against RF
offer hardly any protection against LF fields, and
vice-versa.
With their EMC high-tech fleece Aaronia X-Dream®,
Aaronia probably offers the world's most efficient screening
performance of over 110dB, unique in this price category and
with these material characteristics. Still, Aaronia
X-Dream® is easy to handle even for the novice. Aaronia
X-Dream® screening fleece offers simultaneous protection
against high-frequency (RF) AND low-frequency (LF) E-field
radiation. The secret behind this extremely good efficiency
is a patented tissue based on a compound of copper and
polyester. Aaronia X-Dream® is easy to handle and to
install. It can be folded without taking damage, is sturdy,
frost proof, rot proof, breathable and can even be installed
in concrete. As such, it is also applicable for outdoor use
and can thus save a lot of cost.
Aaronia X-Dream® can be used both for screening electric
fields from local LF radiation sources like cables or
distribution boxes, as well as for screening rooms or entire
houses or other buildings against RF radiation. Installation
is performed by laying the fleece in adjacent lanes which
need to overlap approx. 15cm for guaranteeing a closed
surface. It is noteworthy that it is NOT necessary to ground
Aaronia X-Dream® for RF screening! Still, we generally
recommend grounding using our grounding package, as this will
also add protection against low-frequency electric fields
from high-voltage lines, power cables etc.

| Screening
a room: |
 |
To protect a room (such as a bedroom) against high
frequency radiation, the entire room needs to be
covered with Aaronia X-Dream® completely. On the other
hand, if shielding against low-frequency electric fields
(such as the electrical distribution box or in-wall cables)
is desired, only a small area around the radiation source
needs to be covered. Attention: For achieving low frequency
shielding, the fleece must be grounded! For this, we strongly
recommend our Aaronia grounding package. For floors, the
fleece can be installed invisibly under the carpet, or, in a
new building, in the floor pavement. When attaching to walls,
the fleece can be attached like usual wallpapers using a
special glue. If walls are made from plasterboard, wood or
similar, the fleece can simply be "stapled" to the wall.
Though, the easiest alternative is the self-adhesive "PLUS"
version of Aaronia X-Dream®. The surface needs to be
dust-free, free of grease and dry. Attachment to ceilings can
be performed similarly. Doors and their frames should be
covered entirely and completely with the fleece, preferably
using the self-adhesive Aaronia X-Dream PLUS®, yielding
to an almost perfect connectivity between the door's fleece
and the fleece used in the rest of the room. For window use,
we recommend Aaronia-Shield® which allows elegant
installation as an invisible "fly screen". After
installation, the EMC fleece can also be painted and covered
with wallpaper or plaster. It even offers an attractive
surface with the original copper appearance. Our installation
manual makes it easy even for the novice to construct a
screened room without hassle.

| Shielding
a house or a building: |
 |
Houses and other buildings should be protected with
Aaronia X-Dream indoors.
This is achieved by glueing or "stapling" the EMC fleece to
the walls.
In roofs, the fleece should be installed directly beneith the
vapor barrier.
In floors, the fleece can even be installed in the floor
pavement.
Always note that for professional RF screening, a
hermetically sealed enclosure, a so-called Faraday cage, must
be built. Be careful to always leave a bit of overlap when
attaching the fleece to walls, floors and ceilings to be able
to later connect the lanes without gaps! Windows need to be
screened as well. For this, we recommend our
highly-transparent shielding fabric
Aaronia-Shield®. |

Notice:
when using the dB unit, an increase of 10dB is equivalent to
a 10fold increase in strength. For example, 100dB is 10 times
as strong as 90dB, or 100 times as strong as 80dB, etc.
