" Now we're using traditional sheet metal ductwork right that's correct -- figured out I mean. Pieces are lying all over the place here well basically first we put the air handler in the attic right and then we just measure. The distance is between will come down here transfer those measurements of the duct work cut out holes. And put everything together so this resolved -- in place it's not off of blueprints and plans that's correct OK and you your basic raw material is the five foot length of abducting right that's correct does that snap together. It comes in secrets can't speak cramp from the factory pipe woodlands. And as you see Mike doing right now just snaps together. OK and that's been secured with sheet metal screws so basically the sections get put together with sheet metal screws. And then do you have to add. This will take you don't have to but we do that because he gives him much tighter -- So it really an a class job would be screwed together like that and then taped right then what's happening at this end over here. Well this -- here we need. He wanted to join this pipe together and we have to -- this and make some sense smaller -- allowed Brentwood that. But you're reducing the size of the that's correct as we go further down the line. It's that there's that duct work that gets you -- as the trunk gets longer the diameter gets through it is that's and then this at present has to be capped off right right. Might be coach -- off with half the -- So that the end cap will fit. And so the crimping is done by hand. Anytime you have two similar grandmothers. Coming together right he had decrepit. Or reduce it. And then what did now only a couple more screws there. Now at some point you have to have lines that come off this right yes that's how do you connect them. We first have to cut after again we go back to our measurements and we have the Qaeda around hall. And then this -- Jerry's doing an -- do it in the field win win this one more to cut. Now I noticed most of the duct is insulated that's correct and how does that get done. Well we use this stuff insulation. With. It's called vinyl wrap its inch and a half insulation would. With. So it's firing last incident right Annie gets stapled onto the duck right through this product can. So you folded under and pick up. Two edges. These. Folded under. And pick up the edges. And then we cut the insulation out of the hole and what is the piece that -- put in there this is starting -- and -- because it starts a second line going that's correct the flexible lines are gonna attached to that yet. And what's this about this is a volume damper that you can regulate the precise amount -- that -- Vent gets from the attic that's where you balance -- that's correct thanks Peter thanks Peter."
