what should i do ? and what do i need to use

sheathing and spray in foam.

What is it made of? Is the interior 2x4, solid plywood, fiberlgass?
I would say use the 4x8 sheets of foam insulation and liquid nails on pretty much any surface.

its made of wood 2x4 frameing

Foam sheeting at home depot will work. Just liquid nails it to the inside, or if you want to get fancy roll in some pink panther and sheet the inside with the mossy oak osb from lowes...

Save you coin and trouble. Seal around your windows and cracks with caulk or foam. I would invest in a good heater instead.

You could run into a major pain. The stuff starts coming off in all directions and the major problem I have is wasps getting between the insulation and the outside frame. And numerous other bugs. I agree with the heater--it works great.

well it sounds like i need to just seal everything up and buy me a heater

+1 on the heater. Seal all the seams with caulk. The less places you have that scorpians and other spiders can get into is a lot better than what little good insulation will do.

Don't need or want to seal it up super tight. Needs to breath a bit with a heater, and it'll still warm it up. Of course if you build like me there will be ample venting opportunities around doors/ windows/ etc... Some of those cheaper heaters have CO issues.

i am on the finishing touches on my blind. i thought about using the camo utility blanket from HF for the floor but i dont see why putting them on the walls would keep the draft out.

What kinda sealant are you guys using

Regulart outdoor caulking or a expanding foam, then trim foam down to look better.

Old bathroom heater work very well, regulator a must.

Once in my stand I can be basically naked and be comfortable.

For ten buck your stand should be seeled

I built my blinds 4-5 years ago. They are 5 X 5 ground blinds. I used two 4X4 as skids made a 2" angle iron frame and bolted painted 3/4" plywood as my floor. I used 2 X 2 framing and 3/4" & 1/2" Stryofoam insulation forming 1.25 which is the thickness if the 2x2. I also used indoor outdoor carpet on the floors walls and ceiling. It is Wraped in steel siding. It is heavy thus the skids, but it will last forever and no more painting.I have not had wasp in it yet but between the door and everything else it is very well sealed up.
My point is you can isulate but it will cost. Make sure if you make that decision that the blind is somthing that you intend on keeping for awhile and not to keep the cold out because you will still need a heated. I have for it is as much to your noise in as to keep the weather out.

HAHAHA! Nothing more comfortable than sitting butt naked in the deer stand!!!

+ 1 on the heater but i would caulk it up good cause then once you get if warm you can keep it warm for a little while with out the heater if you need to vent it just open the window a little bit. but on the one i'm getting ready to build i'm still gonna put carpet half way up the walls to muffle the sound of me accidently hittin the wall with my boot.

Spray foam - 1 can should work if gaps arent too big - $5
silicone caulk around windows/frames - inside and outside if you have exterior window frames - $3
Brown indoor/outdoor carpet (2) 6x8 - cut to fit between studs and staple onto walls - $30
I use carpet not really to insulate, but to reduce noise. This same carpet works well on the floor. It is all synthetic so won't rot.

Man all this talk about heaters in the 100 degree weather just has me sweating thinking about it! I wish my blind had an a/c for most of November.

Been there and done that. I walk into my stand about 2:00 in the afternoon. Somedays I am drenched by the time I get there. I simply strip down until all is good and the redress and the evening wears on.

seal it good, and get a heater

Get a Mr.Heater it is portable and works great!

yes they do! Have a couple - just need to remember to leave a couple of propane bottles in the blind.

Of course you could use the old timer way of heating

1. 1 lb coffe can
2. 1 roll of toilet paper placed inside of can
3. 1 16 oz bottle of isopropyl alcohol poured over the TP
4. Light and enjoy

It's amazing - the TP never burns - it is just the wick.
