Hi folks,
I'd like some input on the following:

I have to replace some floors & quite a bit of underbelly on my doublewide

Question: besides the 6 mil polyethylene that I am going to put on the ground, do I need a vaporbarrier under the floor (warm in winter)??

I was thinking of doing the following:

1)replacing the floors where needed
2) putting 1.5" Dow Tuff-R board up against the bottom of the floor in
between the joists where there are no water/drain lines
3) stapling Tyvek against the bottom of the joists & stapling 1/2" hardware cloth right underneath that as a rodent barrier

4) where there are waterlines, put fiberglass insulation (without vapor barrier) under the waterlines, then put Tyvek & hardware cloth under it

Does this make any sense? If not please steer me in the right direction. I just got Mark's book but I am confused on the vapor barrier issue (besides the 6 mil poly on the ground)

I would appreciate any help you can give me

Thanks,
Jan

Hi,

Welcome to the site.

I am going to move your thread to the Repair Forum where it will get more attention.

Thanks Yanita,

Hi & welcome. Traditionall the underbelly hangs UNDER the joists like a big blanket with the insulation above it. This is to allow to for the warm air to flow in cold weather. Depending on your location this may or may not apply to you. Greg
