Wheelhouse floor insulating

[Iceman1026]

I'm guessing spray foam would be the way to go but how would foamboard work has anybody tried it?

Used 1 1/2 pink foam with large plastic washers and the perfect length screws. So far has worked great. I do think my holes freeze closed more though with no heat getting below. They shrink quick on cold weekends....but it sure is nice having a warm, dry floor.

Depending on the size of the house, spray foam and board foam will be pretty similar in cost. Last I checked, 2" pink foam was ~$28/sheet. Add in a couple cans of spray foam, misc screws and washers, and a few tubes of PL 300, and you'd save maybe $50 on a smaller house, and $100 on a bigger house. With spray foam you can go over your frame, preventing rust, and eliminating any moisture issues with your plywood from below.

Any idea how much it helped insulate the floor I have an 8 x 16 ice castle I don't have problems with the holes freezing. It seems like it takes a while to heat up the floor with the furnace I was just wondering if insulating the floor would help heat up faster right now once the floor gets heated it stays nice and warm just wondering if I would save LP

Thanks

My last house had a pink foam in the floor(sandwiched between the plywood. Current house is spray foamed and I have to say is alot warmer. I can walk barefoot most of the time.

From my experience i think it helps. I have a 7 x 14 with the floor insulated and it warms up pretty quick. My last house didn't have it and i know what you mean it takes a while for the plywood to warm up to were it gets warm down by the floor.
