The non-expanding version is available as the "blue" can of "Great<br>Stuff" (at Home Depot in the USA).<br><br>Alternatively, use different forms of insulation, such as glass-fiber<br>insulation with polyurethane foam only in spots.<br><br>Note that if you use the expanding version alone, you will do best to<br>determine how much you need to fill the space, then only use that<br>much. This stuff exerts considerable pressure as it expands. If it<br>were my task, I'd get a disposable 1-l bottle, add the foaming liquid<br>to some specific weight, let it expand, then determine the final<br>volume by difference divided by the weight of liquid used. After<br>that, it's comparatively easy. But be aware that the hardening foam<br>will not distribute itself like a liquid, so it may be necessary to<br>add it in stages anyway.<br><br>On Thu, May 31, 2012 at 11:00 AM, Frantisek Apfelbeck<br><<a ymailto="mailto:algoldor@yahoo.com"
