Ok here is the question.
Several years ago we had central air installed. We installed our own duct work. Fiber duct and all the metal boots were wrapped in foil backed insulation. we also used flexible duct to all the vents.
When the guys were installing the central air they told me the insulation on the boots was unecessary on the metal boots.
We have since added 2 wall stacks to the system these are metal so they fit in a 2x4 wall. I noticed before we closed up the wall the 2 metal ducts would get covered in condensation. I'm going to assume that when closed in the wall they will continue to condensate.
Correct me if I'm wrong or not but these wall stacks and boots need to be wrapped in insulation also correct?
If so does this insulation need to be the foil backed? or can it be the pink loose fill you can buy at lowes and home depot?
Also still more. Murphys laws says that we had to cut through a floor joist to get these 2 wall stacks up. we have sistered(sandwiched) both sides of this cut joist. there is very little room to get any insulation in these areas to cover the metal wall stack and metal boots. Would great stuff (you know that wonderful foam in the can that every home owner loves to spray everywhere) fit the ticket here? Seems like it should get everywhere needed to cover the metal boots and wall stacks.
Final question.. Can anything be done about condensation on metal vents?
