SuperIsol Installation for 42" Pompeii

Re: SuperIsol Installation for 42" Pompeii

Just don't lean in too close to the mist...or turn the pump volume down just a bit to avoid the mist (thats what I did). I can't stand wearing a mask in FL heat and humidity.

The mask sounds like a great idea for that product - in regard to noise, I've been to a few too many Black Sabbath concerts for that to be an issue.

So far, I've been cutting my pavers and island brick without a mask - after my shower, my nose is clean, so that's probably a good indicator that the wet saw is working (I hope).

I concur with David - it's nasty stuff. I had only straight cuts, so noise wasn't a problem - a fine toothed hand saw went through it easily. For a circle, a jigsaw with a fine blade would probably be the way to go, or a fine keyhole saw. This stuff is brittle, and it chips and dents easily, especially at the start and end of cuts!

wear a dust mask. Silicosis is no joke. Those insulation blocks throw up a lot of dust.

AND hearing protection.

I'll probably trim the SuperIsol as you suggest, but leave 1 or 2 cm extra sticking out from under the dome.

Just a safety reminder, whenever you are cutting anything except a 2-by-4, wear a dust mask. Silicosis is no joke. Those insulation blocks throw up a lot of dust.

I stuccoed the igloo before I put in the granite counter top. This left me with a rough, exposed, and unsightly edge around the dome. I could not get the granite slab tight to the igloo.

My list of tips continues to grow! That's a good one. Thank you for the heads up!

<snip> I do indeed plan an igloo style with stucco. I'll probably trim the SuperIsol as you suggest, but leave 1 or 2 cm extra sticking out from under the dome. I'm thinking that this might prevent any heat from sneaking out into the hearth concrete. Probably overkill (can't have too much insulation!). <snip>

When looking back, when I built my Casa110 I did a few things out of order.

I, too, used SuperIsol board as my insulation layer under the floor. I left the board the same size as the base structure - just as if I had poured a vermulite/cement layer. I then insulated my igloo with two layers of Insulfrax blanket.

Where I went astray was in the next step. I stuccoed the igloo before I put in the granite counter top. This left me with a rough, exposed, and unsightly edge around the dome. I could not get the granite slab tight to the igloo.

This was cured by adding another layer of Insulfrax [unnecessary but, I had the extra material] and then another complete three-coat stucco layer.

Re: SuperIsol Installation for 42&quot; Pompeii

I concur about the saw. I bought one last summer and it's great. I was a bit unsure at first because it's made in China but haven't had any trouble with it. The stand is pretty cool but I saved the money and bought a couple of ready-made plastic saw-horses and used some left over 3'4" plywood for a table. Good luck with your project.

Ken - this is pretty good saw for the price. I advise purchasing the extended warranty. They have an in house replacement for 2 years and I recall it only cost me $36.00. I fried the start capacitor on mine a couple of months ago. They were out of stock so I fixed it for less than $6.00 and it's still running strong.

Les & RT: Thanks for the super lead and advice on the saw. HarborFreight has a store here in Louisville. That'll be my research field trip for tomorrow if I don't get caught up at work.

Re: SuperIsol Installation for 42&quot; Pompeii

Had I elected to stick with a 'feature' dome like many others on this Forum, I would have cut the sheets around the perimeter of the dome. So in the second photo above, you wouldn't see any insulation, but it would have extended under the dome brick course.

Paul,

Thanks for the clarification. I do indeed plan an igloo style with stucco. I'll probably trim the SuperIsol as you suggest, but leave 1 or 2 cm extra sticking out from under the dome.

Ken,

I've just read ihughes' recent post on the possibility of insulation sheets getting wet, and I should have mentioned that I am planning to enclose my dome with red brick cladding on all four sides and a corrugated iron roof. So I'll end up with insulation blanket over the dome and loose-fill vermiculite between the dome and walls (and on top of the un-trimmed Cal Sil sheets).

Had I elected to stick with a 'feature' dome like many others on this Forum, I would have cut the sheets around the perimeter of the dome. So in the second photo above, you wouldn't see any insulation, but it would have extended under the dome brick course.

I think with a good render coat(s) of stucco over the dome, the likelihood of water absorption into the Cal Sil sheets would be minimal, if not zero. There's been plenty of posts recently on the 'waterproofness' of stucco coats, so I'll leave you to track them down, should you be going this way.

Cheers, Paul.

Re: SuperIsol Installation for 42&quot; Pompeii

Ken, thats the one. You may want to double check the price.......this saw always seems to be on sale at $199. I purchased mine from an actual HF store location which had "extended" the previous month's sale prices. It was listed online at $219 or $229, but the store was selling it at the "sale" price of $199

Re: SuperIsol Installation for 42&quot; Pompeii

Many of us non professional masons have opted for the Harbor Freight 10" wet saw for $199. Surprisingly, I have only heard of good experiences with this inexpensive saw...

Is this the saw you are referring to?:
Harbor Freight Tools - Quality Tools at the Lowest Prices

I'm definitely going to purchase as I'm not organized enough to knock out all the cutting in one day.

Thanks!!

Re: SuperIsol Installation for 42&quot; Pompeii

Rental is a good option for the saw, if you are well planned and can get all of you cuts done in a day or two. Many of us non professional masons have opted for the Harbor Freight 10" wet saw for $199. Surprisingly, I have only heard of good experiences with this inexpensive saw.......mine include. Bought their $30 blade with the saw...cut as well on the last brick as it did the first.
Probably not suited for daily heavy use.....but for a pompeii oven build, is plenty of saw
