I have a radiator in my apartment bedroom that bangs and clanks continually. It remains hot all the time, as it has no on/off dial. I can't sleep with all that noise and heat, so I bought this welding blanket and wrapped it around the radiator. Works wonders! It completely muffles the sounds, and stops the heat from roasting me. This is probably against all known fire codes, but it sure works. I unwrap it occasionally and check to make sure there aren't any terrible burn marks. So far there haven't been any burn marks or even middling brown marks. If you try this, do be careful when unfolding the blanket as the fiberglass is messy stuff and will get on your carpet, clothes, skin, etc.
