Hi. My cape cod style house was built circa 1970. We have a crawl space that I'd like to finish as a play area for kids. I'm concerned, however, about air quality (e.g., asbestos, airborne fiberglass, etc). It appears to be fiberglass insulation - can I rule out asbestos? What's the best way to finish and seal the space? Right now there are bare joists on the floor with insulation in the spaces and nails sticking straight down through the roof into the ceiling. I was thinking of covering the floor joists with plywood base board, putting wallboard on the wall and canted ceiling, and then carpeting the floor. Any precautions I should observe? Any suggestions from folks who have done this already? Among other things, do I need to get my fiberglass insulation tested for asbestos? Thanks!
