Metal Stud Framing Course By The Col.

#82

(M) If you haven't already seen the comprehensive documentation by Colonelcorn76 (Jim Hatch) on Yahoo, for building your gable house, this is a MUST VIEW! This is useful whether you build from scratch or want to enclose a pre-cast Forno-Bravo oven.

(M) I am just starting to use metal studs for framing my igloo and feel far more secure having this guidance available. If you only glance at the photographs you can't help but be impressed by the expertise, detailing, close photography and helpful text at:

Marcel,

I ain't Jim, but I have framed my oven (minus the roof) and can see things more clearly than before as a result. I'll give you my best shot.

A piece of metal track or stud cut to link the two rafters together. I believe these are called purlins normally.

I am laying my roof out differently and I am using collar ties to give more support.

I don't see that in this pic.. but maybe I need to look more closely. Those holes are not intended for attaching, but for running electric, etc.. I screwed everything together metal to metal, using a lot more track than Jim did.

Do I cut the holes for 2 weathertight boxes before attaching the cement board? ___

You always cut holes in the wallboard before attaching if you have the choice. It's just easier. The stability of attaching walls comes in really handy when your working on the roof.

We started with the desire for a 30 degree roof slope and eyeballed it until we liked it. Then I freehanded with a marker and holding the metal framing up.

6- #13 of 36: "RafterRidgeDetail" You seem to have spaced two (2) rafters extra closely together here. Is that necessary? ___

It's clearly (to me because I'm dealing with it) for supporting the chimney flue. This is very similar to what I'm doing.

Originally Posted by Marcel

7- #14 of 36: "RafterBracing" I can see the top flue brace but I can't visualize the "Lower one extends to far rafter which overhangs slab beyond walls". Any suggestions? ___

?

They are sold in 3x5 and 4.8 sheets. I bought the 3x5 purely because it MUCH easier to handle them. Ideally you want as few seams as possible, so you go for the layout that will give you the fewest seams to finish.

Depends on what you put on the rafter tail. I want to go out about 12 inches, but I know I need to be careful lest the weight of the durock (if that's what I use) bends the framing.

? The fascia board looks to me like track, which is what I intend on using. Track has 'tabs'. I may attack some thin wood for the texture.

Looks like wood or fake wood to me. Personal choice.

Pretty sure he mentioned this before (as a yes).

Yes.

14- #24 of 36: "WatertightNail". Is this truly a "nail"? ___ How did you drive it without bending the sheet metal studs? ___

I would prefer to use a screw type that I found for metal framing, but a nail can puncture these quite easily.

Originally Posted by Marcel

15- #25 of 36: "OnduraVentstrip". Is this necessary since no one will live in this structure? ___ I would like to consider alternate roofing material such as "ChemShake", or "CalShake". Would that be a mistake? ____

Keep critters out is my motto. You don't want birds nesting in there or squirrels burying their nuts in your perlite! Venting IS important however, because good venting will extend the life of your roofing materials.

I think you could use any roofing material you wanted. We're considering a metal roofing material that we might put on our house in a few years.

?

They would simply puncture the studs. I agree with you though.. I would tend to want to use screws.

Sure looks like it to me.

Strategically placed purlins to support the chimney.

(M) Thanks, Tarik, for your input.

(M) I probably did not describe the band around the clay liner very well. In the photo, it does not appear to be attached to anything. What I was trying to describe looks nothing like sheet metal but more like a 1/4" copper tube.

(M) Tarik, I'm exploring using (if I can locate it here) siding made from a Durock-Wonderboard- Hardibacker type material which would emulate wood but which is made of cementitious material reinforced with some kind of fiber. I think it may even be available in color. It is fireproof and water resistant. If I can get it I think I'll coat the Hearth stand in colored stucco but use these cement "ship-lap" to emulate wood. What do you, or anyone else think about that? ___

(M) Here is a single image of the copper leaf of which I spoke in a "private" sending to you:



(M) Note the 1/4" copper tubing which is a kind of faux vine tendril.

Ciao,

Marcel

Marcel - I would avoid using durock or wonderboard as it tends to crumble very easy after it is cut. It works well for tile because the thin set fills the voids. I think you would be safer using the hardibacker product. Along these lines, and I know this has come up before, but what is the problem with using standard wood products? After the dome is completely insulated the temperture must be safe enough to frame and side with wood. Or am I missing something.

(M) I am also leaning in this direction. They make siding in various configurations as well as the panel products.

(M) I don't think you're missing anything. I prefer to stick with masonry partly because I don't have any easy way to secure a treated wood mudsill to my Hearth Stand, but also because I think that masonry will be more resistant to the elements.

Ciao,

Marcel

i used durarock (1/2" x 3' x 5') pieces for my enclosure, and it wasn't all that crumbly. just like sheetrock, trying to land screws from two adjoining panels into the same stud results in some potentially crumbly edges, but i just sistered in extra studs where neccesary.

i thought about wood siding on top of the durarock to match the structure behind it, but think i will stick with masonry as well.

(M) You can have your pizza and eat it, too. I'm considering the use of masonry planks. Check out "HardiPlank"at

yes, but the point to me would be to have the total asthetic of masonry. if i want it to look like wood, i'll use wood. it's a good idea though, if you just want the look of wood but don't want to have to put it over cementboard.

(M) Paul, I would not want to argue aesthetics and can really appreciate your respect for the "real" stuff, be it wood, or masonry.

(M) As an aside, having nothing to do with aesthetics, it occured to me that horizontally placed siding v/s vertical (e.g. board and battens) has four advantages: horizontal obviates the need for sharing studs; it should be inherently stronger as it provides the horizontal bracing that board and battens miss; and so it can be applied (at least on our ovens) without a sheathing underlayment. Finally, horizontal placement pretty much avoids seams.

Ciao,

Marcel
