I apologize if this is too off topic, but does anyone have any experience / opinions on that foil covered bubble wrap insulation?

    What I do not like...

    The ratting changes as to the top side and bottom. I guess it's better than nothing, but I personally don't use it. We always insulate inside the duct. Where it is super tight and hard to get to,.like I said you have to do something to insulate. In that respect, I think it's on a Par level.

    how can it be ..

    How can it be a good " duct wrap " ?


    This is duct wrap...it's what all engineering data is based on ( ACCA and all other load calc software and manuals )...including residential.

    This bubble wrap is like an " excuse " , or an " alibi " ( for the guys I see carrying it out of the supply house )...and is probrobly doing more harm than good. With no " R " value to speak of ( and the vapor barrier is legit ) ...the duct is now sweating in an enclosure ( thinking mold that looks like cottage cheese , and eggs burried in the ground for 100 years ).

    My sheet metal installs will continue to be " itchy " ....and I would install fiberglass " ductboard " ( which will never happen ) over wrapping metal with this crap. - frreekk

    Had a customer

    HAD is the operative word here. I was working with a customer doing a slab on grade radiant job who insisted that Double Bubble was superior to 1 1/2" foam board under the pour. He wouldn't budge so we parted ways. Last winter I was called there to "adjust the boiler" (his words) because of excessive fuel use. This was the middle of February and there was no snow for three to four feet around the building. Nuff said?

    Kinda' like the R-70 paint thing that was floating around for a while.

    "thinking mold that looks like cottage cheese , and eggs buried in the ground for 100 years "

    I'm not a mold specialist, but I do know that mold needs water and food, like wood or paper products(sheet rock has a paper layer). So I don't think there would be a layer of mold. I do think that the duct work could rote out though.

    I'd rather install mini-splits instead of ducts anyway.

  • You Guys,,,,,,,,,,,,,,,

    are all talking about ductwork! What about under slab radiant?
  • S. Ebels

    LOL, I hear ya! I too argued with a guy who tried to tell me it`s R11, I walked away! They all seem to get told it`s "equivalent", ya know?

    Those small 50 cfm half -baths and bed rooms that need 100 cfm get awkward on the mini-split deal however. No substitute for a nice central system.

    And now that I think about it , sweat would occur on the exterior of the vapor barrier as well...no mold specialist by any means...but what a pointless product.-mike

    Edit..air leakage in slip and drive joints could provide other components needed for mold I guess...under that nice vapor barrier with no insulating properties...yum , tastes just like chicken

  • Total junk, waste of money, don't use it. That's a period right there ;)
