Fish House Options?

[mossyoak_87]

Building a 6.5 x 9 foot fish house on a budget, looking for some input on what I should use.

Exterior will be barn steel ran horizontally and on roof, framed with 2x2 treated lumber, and a 3/4 treated plywood on the floor. Tyvek and poly to help with wind and moisture. For heat I am going to use an older Pearson direct vent heater (anvil)to help reduce moisture and should heat the small house well.

Insulation: 1 1/2 inch "white" Polystyrene or 1 1/2 inch "pink" Ridged Foam???? Should I insulate floor or is it a waste of money???? If I do it I would simply glue and tack it to the bottom of the flooring.

Interior Paneling: 1/4 in Lauan plywood (will it warp?), 1/4 inch BC plywood, or 3/8 BC plywood????

Was also thinking about coating floor and bottom foot of wall with Herculiner, but don't know if it will hold up.... has anyone else tried this?

Definitely the better insulation is the way to go. You only buy it once, you pay for heat forever. Insulated floor is a big thing too. It will be warmer and will dry up after drilling holes in a few hours. Otherwise it can take days to dry up if not insulated. To insulate the floor I just put insulation on top of the 3/4 floor and then 1/2 plywood on top of that. Nice strong floor. Put lots of screw to hold top layer down. Don't draw them down too tight but snug. Carpet on top of that and you are good to go. I put another layer of 2 x 2's all the way around on top of the bottom wall plate to attach paneling and trim to before adding the insulation and 1/2" plywwod. I hope this makes sense. Luan plywood is good. Even paneling with a luan backing is ok too.

How thick of insulation do you use on the floor. I am planning on adding insulation to my floor and am trying to decide if I should use 1" or thicker.

Sounds like what a buddie are i are building except 12 foot with a v. We're planing on 1.5 or 2 inch pink for the floor. Good luck. I can't wait to get done and on the ice!

1" of the good stuff works great. I used the kind with foil on one side and vinyl on the other. Anything you use will make a big difference. I have even used the 3/8" fan fold insulation and it worked great too. Of course thicker is better.
