Bamboo Flooring Over Subfloor with Closed-Cell Foam Insulation

I am going to nail down bamboo flooring in a winterized camp built on piers with no skirting - an open crawl space if you will. The floor has been insulated from below with closed cell spray foam insulation.

The directions for installing the flooring recommends using felt paper under the bamboo. Since the foam insulation is a vapor barrier, this would sandwich the subfloor between two vapor barriers, which seems like a pretty bad idea. Is there some other material I should use under the flooring or just lay it right over the subfloor?

Thanks.

Putting the bamboo or any other hardwood in a non climatized structure may not be a good idea. As far as trapping moisture, where would it come from? It is sealed from the bottom and the top via your vapor barrier(s). I would have less worries for the subflooring than I would for the hardwood flooring itself. I am assuming it will go through heat/cold extremes.

The camp is extremely well insulated (in a few years it will become our year-round home) and will be kept at a minimum of about 50 degrees even when we aren't there in the winter months. The moisture will come from the migration of warm air to cold.

Spray foam insulation does not require a vapor barrier, so I don't think you're going to have an issue there

Wood expands and contracts with humidity and temperature changes and I infer bamboo would do the same, so I agree with Chandler the temperature changes this would be subject to could be problematic
