Broken reference links

Hi all I've become a bit stuck with research, as many of the older links in the reference section appear to be broken. I was particularly interested to read about / compare different wall configurations to maximise my design materials. There was a document link that states - "This document shows isolation performance of dozens of different wall assemblies". If anyone has a copy of this PDF, I'd be very grateful for a copy Cheers

Thanks for the heads-up. When I get some time I'll take a look at that page and see if I can update the links, or delete them if they are totally dead. I'm not sure if this is the specific document that was originally referenced there, but it's about the best one I know of on the subject of walls: http://archive.nrc-cnrc.gc.ca/obj/irc/d ... /ir761.pdf - Stuart -
