Re: GSBN:Warning Signs was:Re: [Strawbale] 5 perms / no ventilation; and top-of-wall (Mark Piepkorn)

Hi there,

as far as I know Adam in Paris is evaluating to offer an early warning
system to be build in during the constructions. He thingks of producing sets
of chips which last about 7 years, enough to get over eventual children
sickness. If there is interest this might initiate an intersting venue.

His address under CC.

Best wishes, Martin Oehlmann
