Dynamat installation

[Tom Welch]

Wildthing,
dynamat is not designed to block or absorb heat. It is for vibration damping. A thermal/acoustic foam will stop heat, several heat shield products advertise this capability but beware the marketing hype. To really block heat well, you will need something between the heat and you, dynamat wont do this very well or very long if the temps are high enough. 300 degrees or thereabout. Ceramic heat pads work the best but are expensive.
