Hello,

How common is silver foil backed plaster board? Almost every
wall and ceiling of my house seems to use it and it generally
causes havoc with any of the wireless systems that are all
over the house. WLAN (especially 802.11a/b, g seems better),
DECT phones and now the Central Heating.

We recently had our central heating system modernised and as
part of doing so we have the house zoned with Siemens RDJ10RF
wireless thermostatic controllers for each zone. They are
proving to be unreliable. Speaking to Siemens they seem to
imply that foil backed plaster board was unheard of, and that
I cant expect their system to work in such a house.

But then again kingspan insulation etc is also foil backed and
I guess that is increasingly common?

Regards Fergus.
