Insulate Walls or Floors?
I live in an elevated rancher built in 1978. I just removed carpeting
and linoleum from my breakfast room, kitchen, dining room, and living room, all of which are open to each other. I had 3/4" red oak planking installed over the existing plywood subfloor. Winter season has come, and it has been unseasonalbly cold, and I really notice it in the rooms mentioned above. I don't know if it's because the wood transfers hot/cold more than what was on the floors, or because of the really cold weather. I'm in the S.F. Bay area, where winters are normally mild (40 - 50), and my furnace usually heats the house fine, but now it takes an hour or so to heat the house (20 year old gas heater, forced air, below in the garage). When I wake in the morning, the house is 56 - 60, and overnight temps were mid-30's to low 40's. I'm considering insulating the crawlspace under the house, under the new wood flooring. I have good access to all areas under the new wood flooring, and to all exterior walls. I can walk under the entire area. The floor joists are 2 x 10 (1 3/4 x 9), and the wall studs are 2 x 4 (1 3/4 x 3 1/2). I've been reading a lot about insulating crawlspaces, and some say just need to insulate between all the joists, and others say best to insultate just betwee the studs. Of course, doing just the studs would be much easier, since it's doesn't have to be 'hung', and less expensive, since the insulation wouldn't have to be as thick. Any suggestions? |

YOu did not mention the insulation over head. If it is less than about 8 to 10 inches, start there. Then to the walls and last the floors.. Do be sure that the vents under the house are closed so the air does not just flow under it. |

So much so that you have to clear it away to find the ceiling joists. I've closed up all the vents already. |

Not sure how large the joists are, but you need around 8 to 10 inches, more if in a cold area of the country. It is recommended from one to two feet in the attic of cold weather areas. |

Vents are to move air to control moisture in dirt crawlspaces. The moisture comes from the ground. You shouldn't have any moisture issues. |

Do be sure that the vents under the house are closed so the air does not just flow under it. What if you don't have vents under the house, just a concrete slab? Vents are to move air to control moisture in dirt crawlspaces. The moisture comes from the ground. You shouldn't have any moisture issues. I don't because the slab is insulated from the ground by a plastic sheet. That doesn't stop the cold though, and that is why I think concrete should be made with insulating properties. |

Yes, the exterior of all living space is insulated. I'm talking about exterior walls of the crawlspace. It is defined as a crawlspace, but it's really tall.

Are there any water pipes in the crawl space ? If t'were me I'd insulate the walls with batts between studs then add a 1" layer of foam on top of that . I'd also lay down some poly sheet on the ground to help with moisture control . They make automatic crawl space vents that open when it gets hot , you might want to put some in while you're down there . -- Snag |

The right hand walls are the taller ones. Based on what you wrote above, my vote would be to insulate the unfinished "crawlspace" walls first -- basically to help keep the "cold" from getting into the crawlspace from the outside. (I know, technically it is to keep the heat in the crawlspace from getting to the outside through the now-uninsulated crawlspace walls -- since heat energy flows from the warm side to the cold side, not cold flowing to the warm side). After that, if you decide to insulate the crawlspace ceiling, you could do that too. But, I would do the walls first. |

Usually putting insulation between the joists in a crawlspace is trivial compared to getting insulation into wall cavities. No insulation in those exterior walls already? Be clear about what you're trying to accomplish. You made no mention of heating cost. If your problem is that the floor is too cold and/or you'd like reduced heating cost, insulate under it. If you plan to inhabit the space, put something over it to contain the insulation dust. Look up the historical dewpoint. You wanna make sure that you don't condense moisture on the underside of the floor in summer. Vapor barrier may be required. Now, you've just made the crawlspace colder. If there's anything in there that's sensitive to cold, like plumbing, you may need to address that with insulation or pipe tape or ???? Insulating the walls will help. I've lost track of the crawlspace floor, but you also may need insulation and vapor barrier there too. Depends on the ground temperature. I'm in Oregon. If I close the air vents, the temperature under my house is 55F or thereabouts year round. My attic and crawlspace were insulated at the same time, so I don't have any individual measurements of the effect on heating costs. When I changed from carpet to fake wood floors, they felt colder, but I'm not sure it made any actual difference in the heat lost/gained. I fixed that problem with area rugs everywhere. |

You want to insulate both walls and floor. I'd use foam board with adhesive to hold it on the floor above. |

I lived in a place one time which had a cement floor in the bedroom. (No kidding, hold my beer, woman.) One night as I was laying on the bed, watching TV, noticed my one foot was less cold than the other. Some investigation finds two layers of carpet under one foot, one lay under other foot. I moved the carpet scrap to be under both feet, and that was much more comfortable. Since that time, I've moved. However, I've made sure to always have a carpet sample next to the bed where my feet land. Some carpet stores sell samples of old design carpet. Those can make great foot pads. -- .. Christopher A.
