Spray foam (floor) questions??

3 posts in this topic

I am building an 8*16 house with a V front. The trailer is made out of 2*4 tubing on the perimeter with 2*2 for cross braces.

Can I get away with 5/8 sheathing for the floor? Braces are roughly every two ft.

How thick should I have them put the foam on?

Do I have to cover the foam once it is sprayed or will it be fine being exposed to road salt, etc??

If I have to cover it what should I use??

And would you suggest putting the holes in before or after the foam? (i was thinking after and cutting them out with a sawsall).

I never insulated my floor, my thought is, cold air sinks and hot air rises. When you insulate you are not keeping the cold out as much as keeping the heat in. Would it Help? probably some. Worth the extra work and cost? Not to me.

will ice stick to spray foam? If yes cover it so the foam doesn't stick to the ice and frozen snow-slush on the lake.

What ever you do make sure it's closed cell foam and not open cell, covered or not.
