Wheeler, what kind of insulation do you use ? I personally wouldnt use the plastic because that will cause moisture problems. You might want to use 2inch foam and foam spray instead . The foam works as a thermo barrier, think of it as a to-go coffee cup. You put ice cold water in it, it doesnt sweat. Same thing with boilin hot water, cold on the outside nice and warm on the inside, and no moisture build up. The high dollar would be spent in using foam, probably 20+ bucks per sheet, but money well spent. Hope it helps you out..

If you are useing a vented heate I wouldnt worrie to much about the condensation. On the other hand if you are running a ventless I would highly recomend a good vapor barrier.

I don't think you need a vapor barrier. The vapor will come from your breath on the inside and from your heater if it is not vented. If anything you want the vapor to be able to escape. I have a vented heater in a king crow and I do get a little condensation on the walls particularly by the corners. It usually stays at about 50-60% RH inside but with the walls being a little cooler than the rest of the inside it condensates some on the walls.

If you put in a vapor barrier, make sure that you have a good source of fresh air. Two people in a house with a heater running will burn up the oxygen very quickly.

A vapor barrier is probably a waste of money cause you really aren't going to be using it enough for that to be an issue. More likely than not you're going to have too much moisture inside from ice melting, people, heater or other propane stuff etc.

venting your roof will help, just like on your house... has any one noticed any big neggatives on doing this to a shack that gets heavy use in extremes?

Remember, you do need fresh air. You could be building your own coffin.

This is the biggest point. Make sure you have vents if you are going to do it. But as others have said, I don't see a real value in it.

if you spray foam or use styrofoam you probably wont need a vapor barrier. those types of insulation will keep the drafts out. but as others have said, VENTILATION!

I agree totally, I have had several fish houses over the years and moisture is always a problem. If anything do what ever it takes to get rid of the excess moistue.

      We just returned this afternoon from 6 days on Vermilion. We arrived Saturday and enjoyed 3 fantastic days of walleye fishing. My cousin, our friend Greg, and myself fished several of our spring spots and found fish on all of them. Water temperatures were pretty much 65-67 degrees everywhere we fished. The wind was variable and made boat control a challenge at times. Bait was not an issue and we had success on crawlers(Tim), leeches(Greg), and minnows(me). If I had to pick one of those as catching the most fish, it would be crawlers. Our best day totalled 48 walleyes, 4 smallmouth, and 2 big JUMBOS. We ended up with over a hundred walleyes, 12 jumbos 11"-13", and 10 smallmouth to 18". Our biggest walleye was 24.5" and the balance went from 13"-22". There are lots of 14"-16" walleyes this year which are perfect eaters. The mayfly hatch was in full bloom in some areas but we found very few mayflies in the water column over rock reefs. We caught our fish in depths ranging from 10' to 32'. I didn't fish in any area where I could see mayflies top to bottom in the water column. Slow trolling in the .3mph to .6mph worked and we caught nothing using slip bobbers. Terminal tackle was a 3'-4' 10# flurocarbon leader, 2 lime colored beads, and a plain #6 Gamakatsu walleye hook . Snags are always an issue when fishing in and around the rocks and when the fish are biting they are acceptable. NOW, for the bad news.......Tuesday was a day I won't soon forget. The area suffered devastating torrential rainfall. Lightning was non-stop for several hours and when things settled down, flood damage was everywhere. We checked our rain guage on the side of the cabin and we got 7 3/4 " in a little over 4 hours! Breezy Point road washed out, Mud Creek road washed out as did several others in the area. Cooke business area was completely covered with flood water. I would consider it a disaster area and should be declared as such. We couldn't find a dock anywhere that wasn't covered with water. People were stranded behind flood covered and washed out roads. Dock decking, limbs and such were floating everywhere in the big water. My group sends our prayers to the people of that beautiful country that lost their businesses, homes, and suffered damage to their lake properties. The people of that north country are resilient and we have confidence that they will recover. We stayed our final 3 days but didn't fish at all Tuesday. Our last 2 days showed the effects of the storm. Water temps dropped to 64 degrees and our premo fishing became 10 walleye days. We did manage to catch a dozen really nice jumbos. We plan on returning in September and we pray the area will have returned to normal by then. I haven't figured out how to transfer photos from my phone to my computer yet so no pictures at this time. Good Fishing and God be with you. MarkB

      Word is that the river has peaked and therefore the town can start the process of recovering sooner.
    • smurfy
      Heard that too. Also heard 38 was closed for a but north of rapids due to flooding.    I know the water really came up when I was up last week compared to when I was there in April. 
    • Kettle
      Someone said 4 inches in the past week, more expected this weekend. A few roads, including county roads that are asphalt ended up with sink holes. Lakes are the highest I've ever seen in the 30+ years coming to the area and now living here. Several people lost trees Tues night
    • smurfy
      Dang Kettle  that bites. Great to hear fishing was good though.   How much rain you get up that way?
    • Dash 1
      50 in 6 hours is great. Boat issues really put a damper on a great day though. Hope you get it fixed quickly.
