We are in the process of building a glass victorian conservatory on our home Here is a link to a similar product so you will have an idea of what I'm talking about

After pouring the foundation, the contractor set up the knee wall around the edge of the foundation and the plan was to have the mason brick the exterior of the kneewall within a matter of days. In the interim, the contractor installed floor joists on the concrete slab and placed fiberglass insulation between the joists and a subfloor on top of the joists. He then placed a sealent on the seams of the subfloor. Immediately after the mason was finished, the walls and the roof of the conservatory were to be erected and the unit was to be dry. Unfortunately, there were delays in getting the brick work done and in the interim, the Midwest was deluged for the past 5 weeks with rainstorms. The subfloor (and possibly the insulation beneath) have been exposed to constant heavy rains for the past several weeks. We are very concerned about damage to the sublfloor and possible mold growth on the subfloor and the insulation. The conctractor said he will rip up a part of the floor to see if it is wet below. He believes that even if the insulation is wet, it will eventually dry out(he says we'll see condensation on the glass as it dries). While they have not ruled out replacing all of the insulation and the subfloor, I believe that they will try to avoid doing so.

Are our concerns warranted? Assuming that the insulation was exposed to water, will it simply dry out without any concern for its usefulness, or mold growth or odor? Is the subfloor able to withstand all of this water without permanent damage? Would we be reasonable to simply insist that the subfloor and insulation be replaced, since it was supposed to be under roof in less than a week after it was laid out? Any advise would be appreciated.

Thanks!
