Creating accurate insulating materials in Revit

- [Instructor] In this lesson, chapter 202 we're going to create an accurate insulating material. I've already created two different ones, but I'm going to go through the process of creating one, that's going to be the Celotex XR4000, and what we need to do first is click on the Manage tab, make sure we're on that, and then click on Materials. This is then going to load up the Material Browser and a couple of things we need to make sure that we've got is this thing selected as such. If it's looking like that, then we don't get this bottom panel, So we're going to make sure we can see the bottom panel, and then if we click on Insulation, we can see that we've got quite a few different types of insulation already loaded into Revit. They're not necessarily in the project, these are the project materials, these are the ones that we have access to in a database. So if you come down to these two in particular, the Rigid Insulation and the Rock Wool, I've created the Celotex XR4000, which is a Rigid Installation, and I've also created the rock floor which is a minerable based one, but if we click on this and see what Revit gives us, and we're concentrating really on the Thermal properties, now, the Thermal Conductivity is quite far out on this one. Celotex claim that their thermal conductivity, the K value or the Lambda value for their product is 0.022, so that's much better than this one. The Density is 33 kilograms per meter cubed, so we can adjust that as well. As far as the Rock Wool goes, they've got 0.034, and the Rock Wool data sheet gives it 0.038. Okay, so it's slightly poorer performing than the one given in Revit. The other thing I'm concerned about is the density of it, I'm pretty sure it's not going to be 200 kilograms per meter cubed, more likely to be something like 60, 50, 60 kilograms per meter cubed, so we can make an adjustment on that as well. Now, the process for creating a new or duplicating a new material. If we click on this and send it into the project, it might already be there, but we'll click on this arrow, this sends it into the project. It's already there, so we get this Duplicate Appearance Name thing, so we'll just replace it, and this is our Rigid Insulation. So it's exactly the same properties as we had previously, but now these things are editable, they're not editable down here, and I'm going to right-click on this and duplicate it. So I'm going to call this Celotex XR4000. So there you go, Celotex XR4000, and then we can start working through some of these properties. So I'm clicking on Identity first, that's fine, rigid insulation board, that's okay. The Graphics, it's got kind of a light color, it's not a gray, so we can click on that and just move this up, make it sort of a lighter gray. This is red, green, and blue all set at 230, something like that, it's not essential that it's the same value, but it's a much lighter than the gray. The Appearance, we're using a Flat/Matte Spray, it's a wool paint color, It really, again, doesn't matter for the purposes of this because it's highly unlikely we're ever going to see it exposed in a render. The Physical properties however, this is where we need to consider making some changes. The Mechanical, that's where the density comes in, and I know that this is 33. So what we're going to do, we can see here this hand has got a number one next to it, and it's set there as Polystyrene. This is the asset, and we don't want to use this asset, we don't want to update it either because it's going to update the polystyrene asset for the other material. So what we need to do is click on this thing here, this duplicates the asset, and then we get zero there, and then we can just change this to Celotex XR4000, and I'll just make a copy of that, so Control + C and then description, it's not an expanded polystyrene foam, it's a PIR, so that's polyisocyanurate, and we can probably leave, I'll change EPS to PIR, and then foam structural Plastic, that'll do. And then the source, we can change that to Celotex. And Source URL, if you wanted to, you could put that in there, we can forget all this stuff, and the density is going to be 33 kilograms per meter cubed, so that's all good. So then we can go to Thermal, and again, the thermal properties are shared with the other one, the rigid insulation, so again, we need to duplicate that asset, and this time just paste in the Celotex XR4000, and again, we can call that PIR, and again, it's not a bead board, it's a foam. Closed cell thermal solid, that'll do. Plastic, Source, Autodesk, we'll call that Celotex again, and then we can come down and change these values here. So thermal conductivity is 0.022 and we've got the density of 33. Okay, so that's all set, now I'm going to click Apply and that should then give us our Celotex XR 4000, and it's exactly the same process for the rock floor, but what I have done is created these two for us anyway. So if we come down to the libraries and click on Open Existing Library, and then browse to the CH02Floor Design folder, and it's this one here, the Insulation Materials.adsklib. Once you select that, click Open, and that's then going to give us these two. So all you need to do is send this one into the project as well, and you have two new insulating materials for your floor. And that's the process. The main thing to consider is this thing here, the sharing hand, if it has a number against it, then it is shared with another material, and so if you update it in this, it's going to update it in that, and always make sure that you click on this thing which duplicates the asset. So now you can say OK and now we're ready for the next lesson which is to actually build the floor that we want.
