Q
Can this be used to suppress the sound of a banging radiator for the home? We don't turn the radiator on but it bangs when the pipes warm up in the whole apartment radiator system. I want to wrap this material around the cold radiator for sound suppression but want to make sure it won't catch fire if the radiator accidentally comes on. Also, Is this material non toxic if we are breathing in the same room or if we are sitting or sleeping next to the radiator if it is covered in this material?

Greetings Caroline. thank you for your question. We would not be the best to answer this. We offer this for vehicles to reduce road noise, and as a liner in a floor or roof to reduce interior heat. Not sure if it will work for the application, you need it for, but you can call the manufacture at 513-860-5094, see what they might have to say about your application. It is rated for temperatures up to 350 degrees, and because it goes into a vehicle that is driven daily, I doubt it is toxic.

I see no reason why not, Darryl. The Dynamat Dynacore is designed for use in high heat environments but could also be used for a sonic upgrade to your speaker cabinets. It offers outstanding low-frequency absorption and is lightweight, flexible, and compressible, plus it is self-adhesive so it will stay where you put it!

Greetings James. Thanks for your question. What maybe be best, we dont know what would be best for sound deadening a JD Gator, but most anything is going to help. We sell a lot of different products from the Dynamat company. Depends what location you need the sound deadening.

Q
What is the NRC rating?

A
Dynamat does not list the NRC rating in the specifications for the DynaCore Thermo-Acoustic fiber in 1" thickness, Court. I reached out to Dynamat directly, and this is due to that specification being closely guarded by Dynamat. What they could divulge is that the DynaCore works extremely well to absorb sound in the desired install location!
