Can you tell me what amount of vents should be in the skirting of a mobile home?
Yes, the area under a mobile home is considered as a crawlspace under a house, if it is not heated. That is a vent area of 1 square foot for every 538 square feet of floor area. Vents should be uniformly distributed on opposite sides of the mobile, and designed to prevent the entry of snow, rain and insects. You can purchase these crawlspace vents made out of colored plastic which will slide and close during the cold months.
