Halogen Dome light - heat insulation material 'crumbled'

We just bought a house that has a bunch of Halogen dome ceiling fixtures. We've been pulling them apart to clean them and notice that on several of them the circular silver insulation material is old, dry, and cracked - some even no longer holding to the upper base of the light. These are 150w halogens on dimmers fo the most part. The 1 side is silver, the other side is like a think layer of insulation batting.

Is this dried out insulation material dangerous or a fire hazard? Is it replaceable and if so, where do we find this material? We've seen some insulation stuff at ACE hardware that is 'silver' on both sides but not sure whether there is any batting inside it.

thanks in advance

In another case I would tell you to not be concerned, but with halogen lamps I can't. I am surprised halogen lamps are still available. They are dangerous as they get extremely hot. That is why the insulation ring behind the fixture is deteriorated. Remove a lamp and see what the maximum lamp can be! The maximum wattage is listed inside the fixture. 150 seems high even for a regular incandescent lamp. I think you have the wrong size lamps.

You should either replace the halogens with the correct wattage or go to a safer lamp.
