Installing insulation in basement ceiling
 

I know this question has probably been asked 1000 times but for some reason I can't find the answer...

I am putting insulation in my joists in the basement ceiling (primarily just for sound dampening). All the lighting that I bought is rated for insulation contact so I am not worried about that. What about the heating ducts? Can I put insulation in contact with those? Any other factors that I should be aware of before I start installing this?

Thanks

The heat ducts pose no problems. Are you using faced or un faced?

It is faced on one side, with some sort of clear layer on the other just to hold it together (for easily handling the package says).

I was going to lay the paper side down, but in the joists with the ductwork should I put it face up so the paper isn't in contact with the ducts?
