I know I'm getting in a little late on this conversation, but I hope not too late. Have you guys who are planning to use ice dam underlayment products seen what a mess some of the poorer quality ice dam products make of a roof when everything goo's together? Has any one asked if these products might ooze adhesives or something? Don't most asphalt products tend to run and goo around when hot?? Not trying to dissuade any one on using these products, I just wanted to add a few thoughts of what to watch out for. The big thing I don;t like about them is the weight they add. Some of the bubble products are much lighter. Bubble packaging may not be such a good thing, it probably will deteriorate over time. Bubble insulation for under concrete floors where in floor tube heat is being installed might be a great solution too. just some thoughts, Armand ----- Original Message ----- From: "Frank Swygert" <farna@xxxxxxx> To: <amc-list@xxxxxxxxxxxx> Sent: Thursday, October 30, 2008 9:03 AM Subject: Re: [Amc-list] Sound mats and belts. > Go to the local building supply and look for an asphalt based self stick insulation mat. It's designed for sealing around doors and windows and comes in 6", 12", 16", and 24" widths. It's very similar to Dynamat but at a much lower cost. I don't think Lowe's or Home Depot has it, but a local building supply does. Can't recall the name of it, but a local rod shop has been using it for years. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
