Reminds me of that ductboard from the 70's. it was silver back, looked like aluminum fiol.
Those thicknesses are 7/8ths and 1 and 3/32nds.
Old board 1 inch and 1 1/2.
looks heavier as well.

If we cant have asbestos, then I want to see em outlaw firberglass also. At leaste wherever it is used in an "un-sealed" manner, such as in insulated metal ducts!
Airborn fiberglass is NOT a good idea.
That new duc board sounds like the best idea yet.
Fiberglass is fine for bathtubs, corvettes, hot tubs and a variety of other uses.
However ... pink panther batting in walls/ceilings ... no bueno! Fiberglass stapled to sheet metal has never been something I considered to be professional! Not even for a moment!
And the mere mental image of "wrapping sheetmetal ductwork with fiberglass in order to insulate it" ....... I think glay would work better.
Of course I would never advocate usig clay to insulate ductwork. But then ... I wouldnt do so either for fiberglass.
And if they do come out with a law to ban fiberglass insulation, I just pray they have the reason to NOT begin the abatement process like they did to asbestos.
I'll go visit the doctor and get my lungs xrayed for asbestos. I was around it a lot during my youth.
If my lungs are clear, then I think asbestos was a hoax.
It dont take a "market man" or a "rocket scientist" in order to realize there is just something very very wrong with using fiberglass as a building material when it goes airborn quicker than you can say "fos-gene"!

I will never like it. I know some of you guys love it. But I don't. I think it's awful. And as for plumbing, I think that plastic CPVC running in $500,000 homes for water is to the point of absurd, I can't get calm enough to even beg to ask why that got approved.
Jerry,
I want you to know I meant no disrespect when mentioning your name in my earlier post. I know you dig it. And that job in that picture tells me you have built your business the right way, with craftsmanship still counting for something. I applaud your efforts, and hug hug kiss kiss and all that.
But.
I always sort of knew you on here as a refrigeration man first before you went into hvac. And it shows, with that sternship you have about running soft copper. Now, my question is, if you refuse to use soft copper almost exclusively but at times you must, the same guy here, I am to understand he accepts Ductboard as not as a last resort but something to consider equal that of metal.
Crazy old man..

. And don't you forget it.Ductboard dose not deteriate until you get over 2500 ft per minute air velocity. We design our systems for 700 ft per minute.
Sheetmetal systems can leak up to 20% in a typical residential system. A ductboard system leaks 0% air.
Asbestos can not pass into your blood stream. Fiberglass can pass into your blood stream like dust and pollen. That's a good thing because you shi+ it out eventually. Asbestos just builds up in your lungs.
Ductboard does not support mold as readily as sheetmetal.
Many D's, NO, I would never get offended by anything said on here. This is all about an exchange of ideas. I just hate to see a young guy like you get a closed mind about something when you don't have all the facts.
Wait till you hear this all you plastic pipe haters. We are doing an old hospital, being converted into senior housing. Sprinkler lines run throughout. All in plastic. Massachusettes has approved a special plastic for residential sprinkler use. These apartments are considered residential. It is a special plastic and it is orange in color.

I've installed ductboard systems in basements and later that winter had the customer call. They wanted a few heat runs installed, they were afraid their water pipes were going to freeze. Thats tight. I feel the same way about ductboard as other products. Remain open minded and try it out.

I have seen that orange/red sprinkler pvc, first time about eight years ago. does not work in R/A plenum's.
I have seen plastic pipe off chiller water pumps, they had some type of rubber expansiom joints for vibration and stretching. still could not belive my eyes.
One time I knew this one company that went to a rubber and hose factory, they had 100 foot hoses made up for running under computer room floors.

ductboard is all they use in miami florida
and as long as i aint got to touch it, i like it
it makes for easy plenum hookups, it seals very well
uhh its quieter than metal
all you need is a duct knife a red and blue tool, tape, and your good to go
i seen fiberglass duct sytems that were 20 years old that still look brand new
ductboard is not as bad as yall make it out to be
everyone should experience rolling in some duckboard atleast once in their life
