Home insulation question...

[rabbidrabbit]

OK,

still working on a room remodel plan and I have a question regarding insulating a trussed ceiling.  The trusses are 2x4 16" on center.  What I was planning to do was toss up some r-30 bats but I'm wondering if aluminum barriers are what they claim to be.  Are these worth tossing up?  Here is a ebay link to one dealer..

This stuff worth the time/money?

You sure you want a vapor barrier in the ceiling?  I thought that stuff was for floors and basements, but I'm not an expert.

My attic had about 2 ft of blown insulation piled up and although it was a tad untidy, it worked well enough and due to immediate placement of poison after the build, it didn't even get rat infested.

They talk about putting it in the ceiling..   I'm wondering if this stuff is all that its cracked up to be or just hype...
