In this way, should you insulate rim joists?The time-honored practice of insulating rim joists with fiberglass batts is no longer recommended. Because fiberglass batts are air permeable, they do nothing to prevent warm, humid interior air from contacting the rim joists. During the winter, when the rim joists are cold, condensation can cause mold and then rot.Beside above, what type of insulation do you use for floor joists? Foam, not fiberglass, is the right choice The best insulation material for crawl spaces is rigid foam insulation board. Instead of installing the foam insulation between floor joists in the crawl space, the foam board is installed against the crawl space foundation walls. Also question is, are rim joists load bearing? The main job of a rim joist, also called a band joist, is to provide lateral support for the joists, to prevent the joists from leaning under the weight of the load-bearing walls resting on them. The rim joist also covers the ends of the joists to cap off the joist cavities, the open spaces between the joists.How do you put a Vapour barrier in a rim joist?Vapour barrier up to under side of floor joists and tuck tape it or caulk it. Above that put in between the floor joists 1 inch thick pieces of rigid foam board bought in sheets 4x8x1inch and spray foam around them when you get them in place because they won’t fit perfect.
