I have a problem with my new shop I brought home today.

[wow]

Here is the problem. It's 24' long by 8' wide by 8' high. It's EXTREMELY well insulated:

The problem is that there are no windows, no door, and no space inside. Do you suppose that's an issue?

[wink]

Actually, this is the SECOND load of foam boards that are going on the ceiling in my shop. When it's done I'll have around R60 for my ceiling. Oughta make the heating bills a LOT less next winter...

Right now, though, it just looks like a great big stack of WORK!!!

Wow, that's a load of foam!

must be a very nice size workshop.

Hi, Was spray foam  ever considered? seals the gaps much better. Good luck with that.  [eek]

It's 1800 Square Feet / 167 Square Meters.

Yes, but to get the R-value I wanted was going to be like $16,000. I can do a lot of work and sealing for that kind of money!

An igloo?

What, you couldn't find any green foam?  Whatsamatter you?  Just think of the Festool Cooler you could have with that amount of foam...

Or use some sort of spray foam to fill the gaps between these panels?

Heh, I've been in that situation before.  It's kind of weird having a load that big but that light.  

Going to be in the situation again this summer, if we can ever come to an agreement on the property I'm trying to purchase.  

The bldg I want to become my shop is pretty large, about 8k sq ft, used to be a manufacturing facility filled with sewing machines.  Has a couple of Modines, but they never insulated most off the building, standard block walls for most of it.  Some small parts are insulated, but those were the offices.  It also happens to need some roof repair, probably served best by a full replacement.  Then there's the second building on the property, needs more work, would add about 6k sq ft to the roof total.  Probably rent that one out or just let it sit as storage.  Could likely use a new roof as well.

IF, and that's a big if, I get the property, I'm also going to be picking up a full spray proportioner system for doing foam and coatings.  My reasoning behind this is fairly simple, as part of the negotiations re the property I've had contractors in to give me quotes on what needs to be done to make it work for me, and the roofing and insulation guys were insane.  First off, the spray insulation guys in my area won't do roof coatings, and the guys that do spray on roofing won't do insulation, so if I want things done that way, I need to use two contractors.  Secondly(maybe should be first, $$$ is important, lol) is the cost.  For insulation and roofing the two buildings, the quotes tally up to nearly $60k.  I can buy the other things I need for installing sprayfoam for under $20k, and materials should cost me about $15k.  

Then of course, there's the fact that when we finally do get around to building our "cabin" on our camping land, I want to do a monolithic dome set into the hillside, and foam plays a big part of that structure.

Well, from experience with foam, it can be dyed.  Fairly easily, all you need is RIT clothing dye.  Same stuff we used in school to make tye-dye shirts, lol. 

Easiest method is to dip the foam sheets in the dye solution.  Last time I had to do this we made a 5x10' tray out of 2x4 and an old billboard tarp(coated PVC, I've seen roofing materials less durable than these billboards). 

If you need/want to do it to foam that's standing/installed, it's doable, just requires two people.  One to spray the dye solution on with a misting sprayer, one to follow with a rag mop and sop up what doesn't soak in.  Going to get better color and saturation dipping, but it can be a pain trying to deal with that many sheets o foam dying and drying.

Well, with the addition of the mezzanine I guess you could say it has an 'attic' lid?!

Wow, are those fire rated? If so I'd like the details on the product, I've got the opposite problem in a garage I want to keep cooler when it's 110 degrees in the summer. Also how do you attach it?

No EPS product is fire rated. In a habitable area you must cover it with something like sheetrock. In a detached shop like mine I can leave it exposed.

Ultimately I want to put a ceiling in there though...

Paul G, 

You can get spray foam that's fire rated, but I don't know of a manufacturer that sells it in premade sheets.

There's also a variety of coatings designed to bring the fire rating of spray foam up to Class 1 standards, for example, Certainteed has CertaCoat, a latex based intumescent designed for their CertaCoat sprayfoams.

Certacoat is a nice product. Expensive, but nice. But it's an Ignition Barrier, not a Fire Barrier.

I am unaware of any spray-on coating that would make EPS suitable for a habitable area - AFAIK you must use a product like 5/8" firecode sheetrock. (P.S. my daughter is a state fire marshall and I grilled her on this as well.)

If you know of something, please let me know 'cause I'd be interested big time!

Ask your daughter about fire rated sheetrock vs. fire rated plywood.  I used fire rated plywood in my shop and have been wondering about the difference.
