ic rated can remove paper or not

[mh183]

insulation installed in basement ceiling paper side down, can you install an ic rated can by just pushing it up in to the paper or must it be cut back 3". building inspectors do not allow the paper visible due to fir hazard i need a code article fire building or electric ..

 

[rcarroll]

I would not push the can up into the paper or insulation. Check the listing of the can & see if there is a clearance to combustibles. The IC can is rated for isulation contact.

The fire-resistance is maintained when the insulation's vapor-barrier paper is held against drywall. It's not really fire-resistant when away from such a surface, so I do agree with cutting the paper back.

i would but i need a code article the manufacture states ic contact although i think all paper all around is over doing it any code ibc nfpa or nec

 

[jumper]

The fixture says insulation contact or paper contact?

 

[mh183]

ic the paper is part of the insulation

Not all insulation has paper . Look at this fixture

the installation instructions show no paper or mentioned, I would say that only paperless or blown(loose) insulation is okay. Paper would violate manufactures instructions, 110.3(B)

And what about blown in insulation that is made of paper

i sent an email of to the co. a phone call to day gave a vague answer, just insulation is insulation i was hoping some one had an article from a fire code

They make insulation out of paper? I did not know that. I have only seen the white fiberglass stuff. I do know how that would come into play. Is the paper treated with a fire retardant?

Sorry, I do not know about fire codes very well, but paper on a light fixture just seems wrong.

treated

treated

It is fire retardent.

 

[drive1968]

Modern cellulose insulation is fire retardant. Even though it is made out of paper, it is not a fire hazard when used with IC rated cans. That may sound incorrect, but cellulose not only is treated with fire retardants, but it deprives any heat source of oxygen better than fiberglass. IC rated cans are rated for direct contact with insulation and cellulose is not excluded.

Owens Corning spec sheet for insulation batts states:

Insulation installed too close to light fixtures may affect the luminaire?s performance. Do not install insulation on top of or within 3" of recessed light fixtures unless the fixtures are approved for such use. This is a requirement of the National Electric Code.

This covered faced and unfaced insulation. Technically, if its IC rated it should be fine, but I would still trim away the paper a bit.

An answer in writing from a manufacturer would really be the cats meow in regards to getting a definitive answer.

I agree with Pierre.

Logically speaking:

Paper burns about 450F (232 C). Your conductors are most likely 90 C rated. If, the conductors are rated for 90 C (maybe MTW in the luminaries at 105 C)and the paper wont burn (support combustion that is) at DOUBLE that temperature, I am sure it will be fine.
