" George sailors here -- this and we're gonna get started talking about insulating techniques what best products to to use that thought. George Eminem and I'm an interrupt you here if -- man ask you to take off some -- your protective garb so we can see you. And okay. There is. But it is a good idea when you're putting in any kind of insulation to wear a particle mask gloves long sleeve shirts I happen and I protection is there are. Though part handsome men see we've had a hidden in there god. Now what we're doing here is we want to get an idea of what the best approach is to insulating this particular type of a building except a break. Urban building with you know up an old roof. Situation like this and if you are putting in what looks like pretty traditional pink fiberglass right."

" Well yes I am -- like this is our specially made insulation it's an. Com and it's still three and a half inches thick well I just exact I was only. 113 and a half inches or thirteen and the difference being that we put more fiberglass in the because the insulation is using trapped there right insulation value -- The smaller the cell of trapped air and more uniform and more efficient it is normally. That -- fifteen and three his engine uses a high density product. And it's maximum. Thermal performance you can see by squeezing it it's a very dense bat. Now it is this used more in commercial applications than in residential regular residential construction. Yet typically. What you're doing is you're trying to optimize the thermal value of the wall protecting this particular case. Because we're dealing with -- nobility and we have metal studding metal conducts temperature right and therefore some. Temperature is going to transmit through the metal stud."

" What you want to make sure is that you're facing the insulation is tight against the interior finish yes and you do you you don't want to compress the material. That is correct let's watch as you fit this one and is here you've gotta do the same thing. To it fitted up against that edge of the metal stud you've also got to cut around. A box right now what I would do. It is I would provide a guideline for where my cuts should day."

" And then using it using a straight edge. Notching out. -- your electrical boxes. I'm going to split is that."

" Our -- gets some of it behind the box. Exactly some of it behind the armored cable -- any wires or plumbing in there you want to split the bat so it goes on both sides that's a good tip. They're in there then. What I'll do is. Open it up on the ends up along the edge. So that it fits in the back lip of the metal studs my next question is just that the metal studs. Metal conducts the cold. And when you add up all the surface. Involved in a whole big wall like this. There's a lot of un insulated. Space even though you've gone to all this trouble -- How do you loved how do you address that issue. One of the things that we're doing Bob when this particular job because of the metal are framing is were going with a high density. Extruded polystyrene. Sheathing board. And this carries an. That's what we're installing a what the obvious what the fund does is it provides a thermal break. For the metal stud. Which increases the effectiveness. Of the insulation. In there. So this could just be tacked on to the studs and a couple of places until just don't wallboard comes up just thought lord that was really right -- fit with the with the metal stud here what you have it is. You can screw the metal the drywall directly through the phone right into the metal stud. And that gives you that extra thermal protection what's the status of I mean fiberglass and prize dairy products like this terms about -- these products here. And think products I had the green guard certification -- and so therefore are are not just wanted to let Bob all chemicals that might provide a hazard. Within the indoor air environment good I've been tested as low emission. Products -- now what are we doing in the roof situation and she got one bat up there is that. I twelve inch bat yep that's -- a twelve inch 38 typically in his ceiling we did go with a low density bat and anytime you are insulating you want the insulation to touch the interior finish okay okay. In the walls as well as the ceiling that if you don't want cold air to go between the insulation and the interior finish that would then short circuit the effectiveness of the insulation. "

" Great -- and one last question -- know we've got concerns especially in tight apartment situations about. Sound attenuated and OK what do we do if you want to try to insulate say the bathroom cavity so that the noises of the plumbing are not heard in the bedrooms or in the living space what's the best product to use."

" Well 88 the fiberglass bat. Absorb Sam. Any -- sound is vibration when the sound gets into that fiberglass it's converted from sound energy to heat energy and it absorbs it. So if you insulate interior partition walls can reduce levels in the wings with in the house."
