A friend of mine used full sheets of Dynamat in his car. Why do you only use squares and rectangles?
A. First of all, the Dynamic Control’s family of products is excellent and that is why we use them as the first stage of our two-step AcoustiSHIELD process. Dynamat’s primary function is to stop large expansive body panels from “ringing” as a result of vibration. We don’t use full sheets of Dynamat because we have found that covering approximately 25% of a panel (the “flat spots between the structural ridges and seams that vibrate) does the same job as covering the entire panel. Full coverage with Dynamat is one of those cases where more is not better – it is only more expensive to the consumer and adds weight to the vehicle. Dynamat by itself, has little or no insulation value and that is why we couple it with Quality Heat Shield which has a laboratory rated thermal value of R-18.3 – the equivalent of six inches of fiberglass house insulation. When we combine Dynamat with Quality Heat Shield we enhance the dampening effect of Dynamat by trapping the remaining sound waves within the he
