Is this duct wrap asbestos


Hello

I had a hvac company out earlier to inspect the furnace etc and I asked about adding a dampener onto a duct line that runs to my sons room. It is cranking it out at 1600 CFM and I want to reduce it for the size of the room. When they went into the attic they said we can do it because that duct has an asbestos wrap on it.

I did some research and it looks like that this is a fiberglass wrap and not asbestos but I wanted to see what everyone else thinks.

Thanks

Not sure that anyone can answer that by visual inspection. A test maybe in order. Just dot make it airborne! For now.

I called another hvac company and sent a pic to them and they said it was fiberglass insulation BUT what is under it is the question. In short they said leave it alone until they come out for the dampener install and they will determine then.

Thanks

The question of whether product X contains asbestos or not has been discussed ad nauseum on this forum, do a search for dozens of threads on this topic. The short answer is that there is NO WAY to determine if product X contains asbestos without a laboratory test. Presumably your furnace contractor intends to send a sample to a lab, since there is no possible way they can make a field determination.

Agree with previous poster, there is no way to tell without testing.

You might get a fairly good idea if asbestos was used when the duct work was installed. i.e. do you know what year it was installed.

If in doubt don't mess with it. It only becomes dangerous if airbourne.

If you are worried, get a specialist asbestos removal company in.
