Cover material for ceiling insulation
I'm looking for a lightweight cover material for ceiling insulation
between joists. In detail: Imagine having a basement. The ceiling of the basement is the floor joists of the ground floor; there is fiberglas insulation stuffed between the joists. I'm beginning to finish the basement. In the long run, the ceiling should be finished, for example with drywall, or with a suspended ceiling. In the short run (for a few years), I want a temporary cover, which prevents the fiberglas dust from coming down all the time, makes the ceiling look brighter and neater, and allows me to hide unsightly electrical and plumbing lines. I know that such stuff exists: Go to a big-box store (Costco, Home Depot ...), and look up at the ceiling. You typically see a white or off-white cover, which looks like a fabric or Tyvek, stretched from beam to beam (typically large glu-lams), with insulation attached underneath the roof. The requirements on such a material include: (1) It must be easy to install, so rolls of material that can be stapled to joists are idea. (2) It doesn't have to be a vapor barrier, but it should be quite tight (a mesh wouldn't do). (3) It must be reasonably fire retardant (for that reason, styrofoam sheet insulation is out, as it is so flammable that it has to be protected by drywall. (4) It should be white or light-colored on at least one side. (5) It doesn't have to insulate, but a little bit of R-value wouldn't hurt. (6) It should not be too expensive, way below $1 per square foot (a tenth of that would be better). (7) I don't need huge quantites, as I'm not building another Costco, only about 1300 square feet. So far, I have not really found anything like this. The big-box stores (Home Depot, Lowe's ...) don't have anything like this. Neither does a well-stocked lumber yard. The closest thing I've found on the web is reflective insulation, typically with bubble or polystyrene insulation, about 1/4" thick. It usually comes only in silver on both sides. The only place where I have found reflective insulation that is white on one side is at TekSupply, but they don't carry that material in fire retardant. Any idea? -- The address in the header is invalid for obvious reasons. Please reconstruct the address from the information below (look for _).

It comes in large rolls (8 feet) available at any building supply store. You can staple it with the lettering side up so that you get a white ceiling. Typar (similar to Tyvek) would work but it is grey colored. If you can't find that, you can try Remay, which is a lightweight spun polyester that is used to cover crops and gardens to protect from insects. It is all white, no lettering and available from farm supply shops. Garden shops usually have it, but it is more expensive and usually narrower widths (3 feet). -al sung Rapid Realm Technology, Inc.
