Thanks for nothing. Why bother to flame? Would have been quicker to help.

Im working on prepping for my garage floor that is scheduled to be poured on Friday. I need to know: How do I insulate the sides of the building? Should the foam be level with the top of the skirt board? The guy doing my concrete said I should have the concrete right up against the skirt...

Are you talking about electric boilers or tankless electric hot water heaters? Also, what really is the difference?

Anybody else?

No rebar or mesh. Just using fibermesh concrete. That's exactly why I'm stapling it to the foam. the last thing I need is to cut every piece of tubing the the saw!! :beer:

What is the psi rating on the lowes blue stuff?? It's not on their site http://www.lowes.com/pd_304089-210-304089.0_4294858106__?productId=3122445&Ns=p_product_qty_sales_dollar|1&pl=1&currentURL=%3FNs%3Dp_product_qty_sales_dollar%7C1&facetInfo= EDIT: Nevermind, it's 25 psi...

Ok so I ordered my kit from blue ridge and got the stapler as well. My pad should only be 4-5" thick so they said it really wouldn't make a difference whether I pulled it up or stapled it to the floor. My questions are: 1- Has anyone on here who stapled the tubing to the foam had any...

I guess you guys are right that concrete really is almost worthless for restricting heat transfer. R=0.08 per inch of concrete from what I see. maybe I'll just be stapling my tubing to the foam and using fibermesh mud!!

What's the concensus on installing pex in a slab on grade for a pole barn? I think having the tubing in the center of the slab will obviously be better for heat transfer but by how much? I found a preview of a good book on this but the page I needed wasn't included. Is the ease of...

Did you staple your tubing to the foam or put it on top of the mesh and pull it up?

Very nice! Who came up with your tubing layout? Also, is it ok to just attach the tubing to the insulation like that? That really seems like the easiest way to go and then just use fibermesh concrete. Or did you lay the steel mesh on top of the tubing?

Blue ridge co looks like a good place to buy supplies. I like their kits and might go for the 1200 sq ft one since it comes with exactly what I need. Thanks! Is there anything special I need to do to protect the tubing when it comes out of the floor? Should I get the pieces from blue ridge...

That was an EXCELLENT price!! I'm just going to hang them low like some guys did on here. I'll look into seamless ones but I heard they are very thin and flimsy as well??!? :dunno:

Anyone?

Ok, so I'm finally getting ready to do my concrete!! It turns out that I have more room than I thought for insulation and concrete so I'm probably going to end up with about 4" of stone, 2" of insulation, and 4-5" of concrete. I'm going to use (4) 300ft loops of 1/2" PVC on 12" centers attached...

I need gutters for my metal pole building (30' X 40') and I'm wondering what the best route is. I priced everything in vinyl from the box stores and it came out to be about $4.28 lf with 3 X 4 downspouts!! That seems a little crazy to me. Also, I wonder about the quality. Would I get a...

So for the insulation under the slab, is there any benefit to putting the foil faced "Tuff-R" or "R-Max" underneath? That may be the way I should go since the R-value of that is higher per square inch than the regular XPS. 1-1/2" will give me about R-10 and the regular XPS needs 2" to get R-10.

So no one on here has done a radiant floor with 1" of insulation?

Well I dug down last night and found I have 4.5-5" of stone. What is the minimum amount of stone that would be ok? What's the purpose of the stone anyway ?

Oh, I guess I misunderstood what u meant by digging out. I'm not doing what u described. I guess I just don't want radiant heat that bad. I think I can work out a compromise somehow though. I'll have to dig down and see how many inches of stone I actually have. If I can't do radiant heat...
