Andre has managed to track down some of the most useful reference documents from the Canadian National Research Council, about isolation walls, floors and ceilings, so I'm posting them here.

It used to be easy to find these on the NRC website, but a few years ago they "improved" their website, and actually made it almost impossible to find them. Basically, you have to know exactly what the document is called and where they hid it on their website, in order to download it. Fortunately, Andre has copies of the best ones, so here they are (Thanks Andre!):


IR-586 : "Sound Transmission Loss Measurements Through 190 mm and 140 mm blocks with Added Drywall and Through Cavity Block Walls"

IR-761 : "Gypsum Board Walls: Transmission Loss Data"

Thanks for these, the Canadian NRC pages are sorely missed. Unfortunately the gypsum wall link is an rar where the others are PDF's. I can download the PDF's but the rar seems to ask for some sort of a player (like my VLC that it recognises but can't display it).

Any ideas?

Yes, you can use a free program called WinRar to extract those files.

I just added a couple of new ones that Andre sent me from his impressive library...
