5.10 Are there any alternatives for Dynamat? It's too expensive! [MM, PK]In this question, "Dynamat" refers to all commercial products that are marketed expressly for reducing ambient noise in the car. Dynamat, Stinger RoadKill, et al. all have similar pricing, so this question is intended to give non-standard options.
There is a material known as "Ice Guard," which is used by roofing contractors. It is similar to Dynamat, both in thickness and density. It is self-adhesive on one side, and seems to work very well. Unfortunately, it is sold only in large quantities (225 ft^2 rolls), and runs about $70 for this much. Perhaps a few people could get together for a roll, or it might be possible to get scraps from a roofing contractor.
MCM Electronics See section 5.2 What mail-order companies are out there? [JSC, JM, MM, IDB] (http://www.caraudioforum.com/vbb2/showthread.php?s=&threadid=97527), sells a product called "Sound Deadening Pads" (part #60-2010) which cost $0.90 for each 10" x 10" square.
CAF comment: Our tests have shown: when a small strip of Accumat across a span of metal is compared to the entire area of metal covered with "Ice Guard", the Accumat product does a better job. The ratio was about 1/6th the material needed to get better results .. remember this when comparing costs [Accumat is one of many good brands of "Sound Deadening" produts]
