Contractors/Builders of the OB...got a question
Posted on 1/28/14 at 10:00 pm

My mom lives down south of Sulphur in a house with a crawlspace (really a Stand space after she raised it to be in accordance with flood regs). Even with her dripping water and the pipes insulated..they still froze up during this freeze and the last one. I was going to try to put a foam core sheathing or foam insulation board up under the floor joists to create the dead air insulation area between the joists in an effort to insulate her floor. My question is: Is this legal? Is this to code? Is there anything that prevents me from doing something like this? She lives WAY outside of Sulphur city limits.

Probably easier just to leave them running when it gets cold...

No code issues that I'm aware of. Once the house was raised, the local authority having jurisdiction approved the means and methods of the construction by issuing occupancy/ building final inspection. Unless there is a specific residential code that I'm unaware of, I don't see an issue.

If she is outside of Sulphur you would only have to deal with the parish. I'm not a contractor but if I'm thinking correctly of what you're wanting to do she would be okay. She must be out toward Choupique or Moss Lake and I wouldn't think you would have any installation issues in that neck of the woods.

We had the same problem at the camp, what we did was wrap the pipes under the camp with heater wire. Then plug in the thermostat and your done. When the weather get under 32deg it turn on and heats the pipe up.

Yeah, she's out by Moss Lake.
That wrap is interesting...
And the water WAS dripping. Still froze...can't let them go wide open!

Bingo...here's your answer. This is how we kept out pipes from freezing on our construction trailer on a project in central NY where the temps got below what we're having in LA right now all winter long.

ditto what BLM said, that's your answer.
however, one word of caution: if you do decide to insulate/close-in the floor joist, you may want to provide ventilation so as to prevent mold/mildew/rot.

I did a lot of work around barataria, la after a bunch of those houses were raised. Most of them had spray foam insulation blown after they were raised to insulate.

Talk with the spray foam insulation guys. We had problems at work with subfloors rotting out on about 15 of the 30 houses that were built in lake charles because the open cell spray foam allowed moisture in but could not escape fast enough. After learning our lesson we built 95 houses around new Orleans with closed cell foam and didn't have one problem.
Just make sure that whatever you do that it does not hold moisture.

I wonder how I do that....and keep cold air out of the same areas? Leave a small gap between the outside wall and beginning of foam board all the way around? Say 1/2"?
Good information regarding mold/mildew.

Thanks. Good to know. I am actually not considering spray foam at all..but I will investigate this further with the foam board application I'm considering.
There is a a foam sheathing used in housing applications for lateral support (rather than OSB) on sides of brick houses that contains moisture barriers...I'm gonna look into that stuff as well and see if that could be used.
Regardless...Looks like I'll go the easy route to begin with and use the heater tape to begin with and see if I could do something else for the flooring. It's not only the enclosing of the piping I want to do, but also see if I can reduce her electricity bills (without the risk of mold/mildew, of course).

Why not just use some fiberglass insulation? Just get some chicken wire, nail it to a floor joist, stuff the insulation in, nail the other side of the wire up. By adding 6", that will help save a lot of energy.

i'm not real up-to-date on applying closed cell/open cell foams yet so i'm no help there.
there does need to be some sort of air flow for mold/mildew prevention. this will lead to cold outside air moving thru but it isn't that much. most of our problems in La are heat related. trapped warm and moist air is what leads to problems. is the floor framing system treated lumber?
ps: i am a house builder so i'd like to keep up with what you do and see how it turns out.
