" OK -- the warm zone has been completely installed in the entire area and all the red lines are. That tubing the pex which will circulate hot water and of course that will radiate into the room and that's -- we're gonna heat the space. The next step though involves putting down our hardwood hardwood floor and our homeowners have chosen bellawood white oak prefinished. Now this is up pretty traditional product this is a full three quarter inches thick by. Three and a quarter inches wide tongued and grooved white oak not a laminated or engineered product just the traditional. Old fashioned wood with new fashioned finish on it. Aluminum oxide finish which I think has a fifty year guarantee. The big concern anytime you've got. This kind of heating system. And a substrate. Rolled into one is that when you start applying your wooden floor with a power nailer. Sooner or later you might puncture one of these tubes and that indeed is -- possibility although we've got the fact that we're doing it perpendicular. To our advantage because we'll always see where we're nailing. But anyway let's talk with Tim who's already got his layout started over here. And up. What choices did you have to make here. The only thing you had to kind of worry about was cutting out for these hot and cold feeds right. Yeah pretty much as you notice the text comes down and the firs return actually runs below this course right here yeah we can see if we look closely right there. That we've got tubing and in this section it's running parallel to the back wall. So is that why you're keeping the first one away from the law. And wanted to split that line with the first one so as I face nailed my first course before I actually come into the Tom -- mine. Angled nailer I don't have to worry about penetrating that right yes that's a good precaution. But then again what we're putting all of this flooring underneath. An area that has nothing but cabinets right I mean just look at the plan over here the the back wall. As the refrigerator right here in this corner -- and it's all lower and upper cabinets kitchen sink in the middle so all of this flooring. Is actually going to be hidden under cabinets. Yes that's correct it's something which is kind of a waste. -- could be Illinois but what what you think of the square footage that you have we have to still apply a substrate down there equivalent to the flaw -- make -- three quarter inch plywood which is going to be pretty expensive exactly so by the time you sit there and calculate that area calculate the area for the refrigerator exactly. You also have the dishwasher that could be brought in and removed. So this is the other point that you were making was sometimes twenty years later ten feet fifteen years later people remodel. Remove the cabinets and it's nice to know of the finished floors to there you wouldn't be able to match this floor that he has -- Well maybe you can I don't know but anyway let's get started with a nail it. Do you start on that end. Yes I'm Marty set up there -- and you're shooting with. A power assisted nailer right that's correct how does that work. That this nailer right here. Has a built in groove on the bottom right here that allows this to sit inside above the -- up. So -- space that -- set that right at the exact spot we're gonna set and the fastener. Then of course the pneumatic. Is just a simple touch here and it shoots it yes it's a lot easier than the old fashioned ones where you really have to pound dog gone. All right let's watch as they go into place."

" Okay Jim what size fasteners are we use he's a two inch staples. OK there you. So it's basically a staple. Stay with his -- not coated with glue and -- galvanized them -- okay. Now one of the interesting things here though is that because it's an old house with a wooden. Substrate instead of plywood and we've got one layer of pile of wooden boards then we've just added. The substrate which has the radiant heat in it which is medium density fiberboard that's a wood product. And then we're pretty solid. Three quarter inches of oak on top of that so we really got to weave almost of natural wooden products and when things I really love about this approach to building. Is that it really is a green approach it's sustainable this is. OK the more we use -- that the more the growers plant really. So that the demand just makes for having more trees planted into the environment. The other thing that's neat about it is that if you did want change the finish at any point you -- sanded down stay in the dark and another another look to it. And the key thing though is that you really cutting down on allergens when you've got hardwood floors in your house's as opposed to other products. Including wall to wall where you're gonna have dust and mold and and you know different situations with. A nice hard finish like this. You've got a nice clean environment most of the time. But anyway after -- back than an --"
