Project: Penthouse apartment in a new building,
4th floor
|
Measure: Shielding with Cuprotect® and
other components incl. shielding concept / remeasurement
|
|
|
Flux density before:
|
2,122 µW/m²
|
Flux density after, dormitory:
|
2 µW/m²
|
Flux density after, living room:
|
1 µW/m²
(+/-3dB tolerance)
|
This shielding measure was realised on the
basis of a shielding concept prepared by „EMV vor Ort“ who
also accompanied the project. The concept combines a variety
of shielding components:
-
Massive brick (T9, 99,7% shielding effectivity, i.e. 25
dB, but only in the frequency range of UMTS: 2.11 to 2.17
GHz;
no shielding within the range of GSM 900: 925 to 960 MHz)
-
Cuprotect® in wall and roof areas; roller shutter
housings
-
Ziegelmeier RF-windows
-
Screed shielding with a metallic screed grille against
DECT and WLAN radiation originating from the neighbour
apartments below
Measuring results after completed shielding:
The essential shielding element in the frequency range
below approx. 1,400 MHz is Cuprotect®, whereas at higher frequencies
the shielding success results from the combination of Cuprotect® and
the T9 bricks. GSM 1800 (1,805 to 1,880 MHz) immissions into
the apartment lie below detection limit.
The remeasurement with spectrum analyser and corresponding
antenna did not reveal any building-biological conspicuousness. The effectually obtained shielding reached 27 dB and more.

Project : Family H., Hüttenberg, Germany
|
Measure: Total shielding with Cuprotect® incl.
individual shielding concept
|
|
|
Flux density GSM + UMTS before:
|
1,308 µW/m²
|
Flux density GSM + UMTS after:
|
0.2 µW/m²
|
This shielding measure was realised on the
basis of a shielding concept with different shielding components.
Prior to shielding and after completion RF-measurements were
taken. |

Project: Family N., Lerchenfeldstr. 16, Freising,
Oberbayern, Germany
|
Measure: Shielding with Cuprotect®Spezial
incl. individual shielding concept
|
|
|
Flux density before:
|
GSM 1800: 1,777 µW/m² |
GSM 900 152 µW/m²
|
Airport radar: 7,877 µW/m²
|
Flux density after:
|
GSM 1800: 1.1 µW/m² |
GSM 900: 0.02 µW/m²
|

Prior to shielding works a professional measurement (survey)
shall be carried out and a shielding concept shall be drawn
up.
A remeasurement at the shielded building shows the success
of the completed shielding measure. The certificate "Das
elektrosmogfreie Haus" (e-smog-free house) can be
awarded if all prerequisites are met.
