Here are a few tips for installing subfloor insulation in crawl spaces and sealing your attic access:

  • Sealair leaksin the crawl space’s ceiling (the subfloor). Leaks are often found around drains, pipes, ductwork plenum’s and wiring. Anyplace the ceiling is penetrated is spot for a possible leak.
  • Be sure to seal and insulate any accessibleductworkin the crawl space.
  • If everything is dry, close the crawl space vents. Vents can suck heat and moisture into crawl spaces, which can cause problems.
  • Make sure and insulate around the edges of the attic access (use a thin weather guard strip or gasket)
  • Insulate the attic cover. Glue some insulation to the top of the cover to help heat from penetrating through the cover.
