How to attach insulation to forms

Hey every one, I'm getting ready to start laying down the foam insulation that will be under the slab for my hydroponic heat in my pole building. The question I have is, how to attach the foam to the outside edge form boards? The slab will be 6" thick and I'm using pressure tread boards between the posts. I'm using "Foamular 250" two inch, 8" high. That will make it two inchs below the slab bottom.

Loctite makes a construction adhesive which won't attack the foam. Its blue in color and I bought it at the Home D. But I forgot the specific product number for right now...

Hey everyone, I am creating a new thread in this forum. I am in the process of installing the "Foamular 250" two inch foam for my Hydronic heat in my pole building. My question is how or what is the best way to attach the foam to the sides? The edge forms are eight inch pressure treated boards, the slab will be six inches thick I will use eight inches of foam on the edges so it will be two inches below the flat.

See attached thumbnail below.. the foam on the side goes up to the slab surface. Attach the foam to the splash boards using nails or screws that have the large diameter plastic washers.

Don't ask.
I glued mine to concrete, it extends higher than the floor.
Sounds like yours will end up being held in place by the concrete. A little glue or a few nails should hold it long enough to pour.

Thanks lake, I thought about just letting the "horizontal" or slab side hold it up but thought it might make it tip out on the top? As for adhesives not shire about it bonding to the pressure treated wood.

I have followed your thread over the last couple of years, great job on your shop! I think you and I are cut from the same thread, "Detail oriented and Profectionists".this has been a great experience for me having never done any carpentry work before, how ever I have always been mechanically inclined I grew up on a farm and took engineering in college. So I have a tendency to over think things! Thanks again for the help! Hey by the way, what is the foot print of the base's on your Rotary lift? Oh I also love your 32' I'm looking for a 32' five window to do with a flathead, quick change, discs, and a 700R4.

Thanks leafless, any suggestions on adhesives? I have been thinking mechanical fasteners but haven't found anything that looks acceptable.

I'd tend to agree.

If it'll be held in place by the concrete, no reason to spend big money on "whatever" to hold it in place.

I'd rob the plastic caps off some plastic cap nails (for roofing) and stick them on some 3" drywall screws.

What I used was a construction adhesive specifically for foam insulation, it came in a tube that fit a standard caulking gun.
