Re: Re: Radon Barrier & Insulation
THat aeroboard has a conductivity of .037. Its not great and you would need quite a but of it to comply with the regs. Compliance with the regs isn’t based on a material basis. Its the thickness that is more important. Any material can comply with the regs. If enough of it is used. The note at the bottom of the should be ignored, it is out of date.
If you want to use this you will need about 100mm or more in the cavity, as well as the 40mm cavity. This will increase size of rising walls. Its not really worth it. Get some better quaility stuff.
The regs and TGDs are available from http://www.environ.ie. Full and up to date sets in free pdf.
