I bought a home with a crawl space, crawl space needs insulation but probably can’t get contractor in before winter.
I’ve ordered new carpet and have already removed the old stuff. would laying down reflective insulation (bubble sandwiched between foil type) help insulate the floor?
In this situation the reflective foil surface of the bubble wrap will do almost nothing. The “bubble” air spaces will insulate, but won’t they “pop” when you walk over them?
Putting down a good 5/8 inch pad under your carpet will help a lot, but certainly the best thing would be to get that crawl space insulated.
Good Luck!

insulating the crawl space would be a fairly easy DIY if there is enough room to crawl in there. start by putting down a layer of 6-10 mil plastic over the entire crawl space ground. forms a vapor barrier and also makes working cleaner then the dirt. it is best to use unfaced insulation batts that are the same thickness as the width of the joists. this will probably translate to R33 insulation batts. if using faced insulation, the faced side goes up against the floor. there should be enought grip between the joists and the insulation to hold the insulation in place during the installation. after the openings are filled, use twine or plastic furnace duct webbing fastened to the bottoms of the joists and spaced 18-24 inches apart to give permanent support to the insulation batts.
