I currently have blown in fiberglass insulation in my attic with no vapor barrier. I want to add some more insulation but I been getting some mixed answers. Here are my questions. (house is 17 and I live outside of philadelphia pa)

(1) Should I add a vapor barrier. I don't see any moisture problems in my attic and the house is 17 years old. My soffits are all vented properly.
(2) If yes (add vapor barrier) should I use plastic sheeting or just use the faced insulation. I know that I have to put the vapor barrier under the blown in insulation. The extra work doesn't bother me. My concern is that the plastic sheeting in not going to be the best solution because I got to work around all of the wires and pipes that already exist in the attic. So it won't be continous.

(3) Does anyone have experience with radiant barrier chips? I have been told just to add them instead of the insulation.

Any comments would be great.

Thanks

Ok. You have blown in fiberglass insulation in your attic.

You want to add insulation.

No problem so far.

The question relates to a 'vapor barrier'.

The ANSWER is: you DO NOT need to add any type of 'vapor barrier' in the attic whn adding insulation. Period.

Why?

Because 'vapor barriers' come in all shapes ans sizes.

PAINT is a 'vapor barrier'.
DRYWALL is a 'vapor barrier'.

The POINT is, you do NOT need to do anything other than to lay unfaced fiberglass batts OR spray in more loose fill fiberglass to increase the insulation in your attic.

If you want to know all the scientific and technical reasons WHY, just ask....

I'm kind fo curious about the extra info!

I'm in the process of doing the same thing (add insulation to my attic).

my house is much older (85 yrs)
there's partial blown in and even some batt insulation between the joists. seems like old stuff. .yellow with a black paper on one side and brown paper on the other.. on top of that there;s loose fill. i'm just gonna make sure all the gaps are filled with loose fill and the I was gonna put a blanket of batt insulationon top of the floor. (the attic floor is partly covered)

I was a little worried about the vapor barrier part..but most everyone I talk to say it's not that big a deal (for the attic)

so..lead me to all this extra info

thanks
