Insulating Your Unconditioned Crawlspace
In a vented or unconditioned crawlspace (not heated or cooled by a furnace or air conditioner) only the floor is insulated. In this short video, we’ll show you just how easy it is to insulate your crawlspace yourself, to protect your home against costly energy loss.
Common Belief: Attic ventilation is not needed when a proper vapor retarder is used on the attic floor.*
Truth: Even with a good vapor retarder, proper ventilation is essential to prevent damaging condensation. Eave vent openings at the roof overhang combined with a ridge vent, roof vent, or gable vents, are effective ways to create a positive movement of air in and out of the attic.
*Note: Check your local building codes on ventilation and moisture control requirements in your area.
