insulation material question

[poultrygeist]

Wow! Think of the chemicals that will eventually get to your eggs!I used fiberglass with heavy plastic vapor barrier. Then the cheapest paneling I could find covered that up!

I actually used both. I bought 4x8 sheets of 2 inch thick Dow sytrofoam for walls and 1inch thick for ceiling. I used a couple cans of the foam in some areas that were hard to cut board for and in some corners and to seal some cracks. The foam is a little messy. But does seal any gaps. I just had to go back next day with Stanley knife and trim any excess. THey actually make some now designed for window and door frames that does not expand as much.

Overall it could be a good product to seal things and for hard to reach areas.

I think that it would be great , we have the same thing insulating our house (professional spray foam, but the same thing as you can buy in the can at HD). This stuff is awesome, our house holds the heat in the winter, and if you cool it off at night in the summer it stays WAY cooler ! This would be great in a coop, but should be covered up, but I don't think that you have to worry about chemicals getting into your eggs !

One thing about GreatStuff is that it won't spread itself evenly into a space. Example, if you want to fill a hollow-core door, and put all the spray into the door through one hole, it will get REALLY thick at that area but other areas will be empty (uninsulated).

I love Greatstuff, it's perfect for filling all the gaps AFTER you put in your rigid foam insulation.

It DOES off-gas , meaning that it will exude a chemical like formaldehyde, long after the initial cure. I would not use it for my chickens unless it was totally enclosed from their sleeping area.

Thanks for all the advise. I would be using a layer of plywood on both sides. Does fiberglass come in a 1.5 inch thickness?
Since I am finally starting to acquire materials today, I will have to look at my options today. I'm trying to build this right the first time.

I have never heard of 1.5" fiberglass batts? I would just use the cheapest rigid insulation you can find, the spray foam only for gaps 3/4" or less.

Hey Scott, we live center state in Vt. We have a 6x8x6 coop. All I did was use outdoor calking on all my corner joints, and any other seam or crack I could see. Like it was said before, draft free and dry is all it takes. Chickens have been living in much worse places than ours for hundreds of years here in Vermont, with no real problem. Besides, Rutland is ALWAYS warmer by 10-20 degrees than central Vt. I would'nt worry a bit. Draft free, and dry.

Might be cheaper than cans if you decide to go that route

Hi Scott,

Here is how we used fibreglass, tuck tape and vapor barrier to insulate our coop. We had the most bitter winter in 22 years and the interior temp never got below -6C. There is also a link from this page to seasonal concerns, should you think it helpful!

I need to do something other than check out this webpage every two hours... I think I'm addicted.
Jafo, new to Rutland (VT for that fact), so I've yet to hear about the warmer here part. I wonder about West Rutland? We are in a different valley than Rutland. Since we are building from scratch, I want to build it "correctly". So not necessary but useful is my approach.
I wonder about taking a sheet of fiberglass and pulling it apart into two sheets, then spray foam around the corners. Since its a small coop/run I don't want to have 4 inch walls. Off to the hardware store for research.
Thanks again,
Scott
